Fauna of Gor
Land Animals

(here you will find creatures that live all or most of the time on the lands of Gor)

Anteater
more then 6 different varieties are found on Gor

More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor page 312

Great Spined Anteater We sat about the small fire, some half pasang inland from the river, in the rain forest.
A great spined anteater, more than twenty feet in length, shuffled about the edges of the camp. We saw its long, thin tongue dart in and out of its mouth. The blond haired barbarian crept closer to me.
"It is harmless," I said, "unless you cross its path or disturb it"
 It lived on the white ants, or termites, of the vicinity, breaking apart their high, towering nests of toughened clay, some of them thirty-five feet in height, with its mighty claws, then darting its four-foot-long tongue, coated with adhesive saliva, among the nest's startled occupants, drawing thousands in a matter of moments into its narrow, tubelike mouth.
Explorers of Gor  page 293

Armored Gatch In the lower branches of the ground zone may be found, also, small animals, such as tarsiers, nocturnal jit monkeys, black squirrels, four-toed leaf urts, jungle varts and the prowling solitary giani, tiny, cat-sized panthers, not dangerous to man. On the floor itself are also found several varieties of animal life, in particular marsupials, such as the armored gatch, and rodents, such as slee and ground urts. Several varieties of tarsk, large and small, also inhabit this zone. More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor Pages 311-312

Bosk
a very large, long horned animal similar to the Urth cow. The meat may be roasted or broiled, dried, stewed or served in various other ways. The skin of the animal is tanned and utilized in many fashions.

Though similar in build to the Yak of earth the Bosk bears the heavier form of the buffalo of earth and like him, provides, food, leather and many of the needs of the people of Gor. The meat may be roasted or broiled, dried, stewed or served in a myriad of ways.
Nomads of Gor. p 4

"The bosk, without which the Wagon Peoples could not live, is an ox like creature.  It is a huge,
shambling animal, with a thick, humped neck and long, shaggy hair. Not only does the flesh of the
bosk and the milk of its cows furnish the Wagon Peoples with food and drink, but its hides cover
the domelike wagons in which they dwell; its tanned and sewn skin cover their bodies"
Nomads of Gor, pages 4-5

Frevet
small mammalian creature, similar to a weasel or ferret in shape, which eats insects. Commonly kept inside a domicile to keep bugs under control. Friendly and curious animals.
Mercenaries of Gor, page 276

Giani
a large mammal of solitary habits which inhabits the rain forests inland of Schendi

In the lower branches of the ground zone may be found, also, small animals, such as tarsiers, nocturnal jit monkeys, black squirrels, four-toed leaf urts, jungle varts and the prowling solitary giani, tiny, cat-sized panthers, not dangerous to man. On the floor itself are also found several varieties of animal life, in particular marsupials, such as the armored gatch, and rodents, such as slee and ground urts. Several varieties of tarsk, large and small, also inhabit this zone. More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor Pages 311-312

Hurt
a domesticated marsupial raised on large fenced ranches in several of Gor's northern cities.  It is a two legged animal and has wool which is sheared four times a year by slaves.  It is herded by domesticated sleen.

"wool from the bounding Hurt"
Tribesmen of Gor, page 37

"Two peasants walked by, in their rough tunics, knee-length, of the white wool of the Hurt."
Tribesmen of Gor, page 47

"I wore a white robe, woven of the wool of the Hurt, imported from distant Ar,..."
Hunters of Gor, page 7

"Her hair was blond and straight, tied behind her with a ribbon of blue wool, from the
bounding Hurt, dyed in the blood of the Vosk sorp."
Marauders of Gor, pages 1-2

Kaiila

"The mount of the Wagon Peoples, unknown in the northern hemispheres of Gor, is the terrifying but
beautiful kaiila. It is a silken, carnivorous, lofty creature, graceful, long-necked, smooth gaited. It is
viviparous and undoubtedly mammalian, though there is no suckling of the young...The kaiila is extremely agile...normally stands about twenty to twenty-two hands at the shoulder, can cover as much as six hundred pasangs in a single day's riding. The head of the kaiila bears two large eyes, one on each side, but these eyes are triply lidded probably an adaptation to the environment which occasionally is wracked by severe storms of wind and dust; the adaptation, actually a transparent third lid, permits the animal to move as it wishes under conditions that force other prairie animals to back into the wind, or like the sleen, to burrow into the ground."
Nomads of Gor, pages 13-14

"The kaiila of these men were as tawny as the brown grass of the prairie, save for that of the man who
faced me, whose mount was a silken, sable black."
Nomads of Gor, page 14

"My mount, a lofty black kaiila, silken and swift, shifted nervously beneath me."
Blood Brothers of Gor, page 7

"I then saw the kaiila pass. It was lofty, stately, fanged and silken. I had heard of such beasts, but this was the first time I had seen. It was yellow, with flowing hair. Its rider was mounted in a high, purple saddle, with knives in the saddle sheaths."
Fighting Slave of Gor, page 178

kaiila, desert (same quote for southern kaiila)
also known as sand kaiila, this omnivorous animal is related to the southern kaiila and similar in most aspects barring pelt color and rearing of young; pelt color is tawny or black and young are suckled for a length of time.  The men of the Tahari Desert use this mount. The sand kaiila, or desert kaiila, is a kaiila, and handles similarly, but it is not identically the same animal which in indigenous, domestic and wild in the middle latitudes of Gor's southern hemisphere; that animal, used as a mount by the Wagon Peoples, is not found in the northern hemisphere of Gor; there is obviously a phylogenetic affinity between the two varieties, or species; I conjecture, though I do not know, that the sand kaiila is a desert-adapted mutation of the sub-equatorial stock; both animals are lofty, proud, silken creatures, long-necked and smooth-gaited; both are triply lidded, the third lid being a transparent membrane, if great utility in the blasts of the dry storms of the southern plains or the Tahari; both creatures are comparable in size, ranging from some twenty to twenty-two hands at the shoulder; both are swift; both have incredible stamina; under ideal conditions both can range six hundred passangs in a day; in the dune country, of course, in the heavy, sliding sands, a march of fifty passangs is considered good; both, too, I might mention, are high-strung, vicious-tempered animals; in pelt the southern kaiila ranges from a rich gold to black; the sand kaiila, on the other hand, are almost all tawny, thought I have seen black sand kaiila; difference, some of them striking and important, however, exist between the animals; most notably, perhaps, the sand kaiila suckles its young; the southern kaiila viviparous, but the young, within hours after birth, hunt by instinct; the mother delivers the young in the vicinity of game; whereas there is game in the Tahari, birds, small mammals, and occasional sand sleen, and some species of tabuk, it is rare; the suckling of the young in the sand kaiila is a valuable trait in the survival of the animal; kaiila milk, which is used, like verr milk, by the peoples of the Tahari, is reddish and has a strong, salty taste; it contains much ferrous sulfate; a similar difference between the two animals, or two sorts of kaiila, is that the sand kaiila is omnivorous, whereas the southern kaiila is strictly carnivorous, both have storage tissues, if necessary, both can go several days without water; the southern kaiila also, however, has a storage stomach, and can go several days without meat; the sand kaiila, unfortunately, must feed more frequently, some of the pack animals is a caravan are used in carrying fodder; whatever is needed, and is not available enroute, must be carried; sometimes, with a mounted herdsman, caravan kaiila are released to hunt tabuk; a more trivial difference between the sand kaiila and the southern kaiila is that the paws of the sand kaiila are much broader, the digits even webbed with leathery fibers, and heavily padded, than those in its southern counterpart.
Tribesmen of Gor Page 70-71

kaiila, southern (same quote above for sand kaiila applies here also)
 large (20-22 hands) carnivorous mammal with long neck and  silky fur; its eyes have 3 lids; is viviparous has incredible stamina (capable of covering 600 in a day) and can be domesticated for riding in spite of its vicious temper.  It has a rich gold to black.  The kaiila is a mammal, but there is no suckling of the  young, who begin hunt within hours of birth. These are the mounts of the Wagon Peoples.

The mount of the Wagon Peoples, unknown in the northern hemisphere of Gor, is the terrifying but beautiful kaiila.  It is a silken, carnivorous, lofty creature, graceful, long-necked, smooth-gaited.  It is viviparous and undoubtedly mammalian, though there is no suckling of the young.  The young are born vicious and by instinct, as soon as they can struggle to their feet, they hunt.  It is an instinct of the mother, sensing the birth, to deliver the young in the vicinity of game.  I supposed, with the domesticated kaiila, a bound verr or a prisoner might be cast to the newborn animal.  The kaiila, once it eats its fill, does not touch food for several days.
The kaiila is extremely agile, and can easily outmaneuver the slower, more ponderous high tharlarion.  It requires less food, of course, then the tarn.  A kaiila, which normally stands about twenty to twenty-two hands at the shoulder, can cover as much as six hundred passangs in a single day's riding.
The head of the kaiila bears two large eyes, one on each side, but these eyes are triply lidded, probably an adaptation to the environment which occasionally is wracked by sever storms of wind and dust; the adaptation, actually a transparent third lid, permits the animal to move as it wishes under conditions that force other prairie animals to back into the wind or, like the sleen, to burrow into the ground.  The kaiila is most dangerous under such conditions, and, as if it knew this, often uses such times for its hunt.
Nomads of Gor Page 13-14

Kailiauk
gigantic, dangerous beast that stands 20-25 hands at the shoulder and weighing as much as 4,000 lbs, they migrate across the Barrens in massive herds, hunted by Red Savages and those who trade in their hides.  They have a trident horn. Kailiauk are four-legged, wide-headed, lumbering, stocky ruminants. Their herds are usually found in the savannahs and plains north and south of the rain forests, but some herds frequent the forests as well. These animals are short-trunked and tawny. they commonly have brown and reddish bars on  the haunches. The males, tridentlike, have three horns. These horns bristle from their foreheads. The males are usually about ten hands at the shoulders and the females about eight hands. The males average about four hundred to five hundred Gorean stone in weight, some sixteen hundred to two thousand pounds, and the females average about three to four hundred Gorean stone in weight, some twelve hundred to sixteen hundred pounds
Explorers of Gor page 93

"I looked beyond Hci to the beasts, some two to three pasangs away. The kailiauk is a large, lumbering,
shaggy, trident-horned ruminant. It has four stomachs and an eight valved heart. It is dangerous,
gregarious, small eyed and short tempered. Adult males can stand as high as twenty or twenty five hands at the shoulder and weigh as much as four thousand pounds."
Blood Brothers of Gor, page 10

"Even past me thundered  a lumbering herd of startled, short-trunked kailiauk, a stocky, awkward
ruminant of the plains, tawny, wild, heavy, their haunches marked in red and brown bars, their wide heads bristling with a trident of horns; they had not stood and formed their circle, shes and young within the circle of tridents..."
Nomads of Gor, page 2

"The kailiauk in question, incidently, is the kailiauk of the Barrens. It is a gigantic, dangerous beast, often standing from twenty to twenty five hands at the shoulder and weighing as much as four thousand pounds. it is almost never hunted on foot except in deep snow, in which it is almost helpless. From kaiila back, riding beside the stampeded animal, however, the skilled hunter can kill one with a single arrow. He rides close to the animal, not a yard from its side, just outside the hooking range of the trident, to supplement the striking power of his small bow. At this range the arrow can sink in to the feathers. Ideally it strikes into the intestinal cavity behind the last rib, producing large scale internal hemorrhaging, or closely behind the left shoulder blade, thence piercing the eight valved heart."
Savages of Gor, page 40

"To the oases, caravans bring various goods, for example, rep-cloth, embroidered cloths, silks, rugs, silver, gold, jewelries, mirrors, kailiauk tusks..."
Tribesmen of Gor, page 37

Larl

As the tarn wheeled upward, I heard the wild, uncanny hunting cry of the larl, piercing the dusk from somewhere in the peaks below. Even the tarn seemed to shiver in its flight. The hunting cry was answered from elsewhere in the peaks and then again from a farther distance. When the larl hunts  alone, it hunts silently, never uttering a sound until the sudden roar that momentarily precedes its charge, the roar calculated to terrify the quarry into fatal instant immobility. But tonight a pride of larls was hunting, and the cries of the three beasts were driving cries, herding the prey, usually several  animals, towards the region of silence, herding them in the direction from which no cries, the direction  in which the remainder of the pride waited.
I caught sight of one of the larls, padding softly along, its body almost white in the moonlight. It paused, lifted it wide, fierce head, some two or three feet in diameter, and uttered the hunting scream once more. Momentarily it was answered, once from about two pasangs to the west and once from about the same distance to the south-west. It appeared ready to resume its pace when suddenly it stopped, its head absolutely motionless, its sharp, pointed ears tense and lifted. I thought perhaps he had heard the tarn, but he seemed to show no awareness of us.
The tail of the animal began to lash angrily. It crouched, holding its long terrible body close to the  ground, it then began to move forward, its hind quarters almost touching the ground, Its ears were  lying back, flat against the sides of its wide head, as it moved, for all its speed, it placed each paw  carefully on the ground, first the toes and then the ball of the foot, as silently as the wind might bend  grass, in a motion that was as beautiful as it was terrifying.
Tarnsman of Gor, Page 149

"I once asked a Gorean hunter whom I met in Ar why the larl was hunted at all. I have never forgotten his reply. 'Because it is beautiful,' he said, 'and dangerous, and because we are Goreans.' "
Priest-Kings of Gor, page 20

larl, black
predominately nocturnal larl which is sable coated and maned both male and female. "The larl is a predator, clawed and fanged, quite large, often standing seven feet at the shoulder. I think it would be fair to say that it is substantially feline; at any rate its grace and sinuous power remind me of the smaller but similarly jungle cats of my old world....The larl's head is broad, sometimes more than two feet across, and shaped roughly like a triangle, giving its skull something of the cast of a viper's save that of course it is furred and the pupils of the eyes like the cat's...the pelt of the larl is normally a tawney red or sable black. The black larl, which is predominately nocturnal, is maned, both male and female. The red larl, which hunts whenever hungry, regardless of the hour, and is the more common variety, posesses no mane."
Priest-Kings of Gor, page 18 larl, jungle On the jungle floor, as well, are found jungle larls and jungle panthers, of diverse kinds, and many smaller catlike predators. These, on the whole however, avoid men. They are less dangerous in the rain forest, generally,  than in the northern latitudes. I do not know why this should be the case.   Perhaps it is because in the rain forest food is usually plentiful for them, and, thus, there is little temptation for them to transgress the boundaries of their customary prey categories. They will, however, upon occasion, particularly  if provoked or challenged, attack with dispatch. Conspicuously absent in  the rain forests of the ua were sleen.
Explorers of Gor  page 311-312 larl, mountain It is said that only the heart of the mountain larl brings more luck than that of the vicious and cunning sleen."
Outlaw of Gor  Page 37 larl, red
predominately day hunting larl which is tawny-red coated and has no mane in either male or female. "The larl is a predator, clawed and fanged, quite large, often standing seven feet at the shoulder. I think it would be fair to say that it is substantially feline; at any rate its grace and sinuous power remind me of the smaller but similarly jungle cats of my old world....The larl's head is broad, sometimes more than two feet across, and shaped roughly like a triangle, giving its skull something of the cast of a viper's save that of course it is furred and the pupils of the eyes like the cat's...the pelt of the larl is normally a tawney red or sable black. The black larl, which is predominately nocturnal, is maned, both male and female. The red larl, which hunts whenever hungry, regardless of the hour, and is the more common variety, posesses no mane."
Priest-Kings of Gor, page 18 larl, white
seen in icy mountains of the Sardar they are the largest of the big cats standing 8 feet; upper canines extending below their jaws very similar to saber-toothed tiger; long tails are tufted at the ends. There was a sudden startled rattle of chains and I saw two huge, white larls frozen in the momentary paralysis of registering my presence, and then with but an instant's fleeting passage both beasts turned upon me and hurled themselves enraged to the lengths of their chains.
Priest-Kings of Gor, page 18

They were gigantic beasts, superb specimens, perhaps eight feet at the shoulder. Their upper canine fangs, daggers mounted in their jaws, must have been at least a foot in length and extended well below their jaws in the manner of ancient saber-toothed tigers.  The four nostril slits of each animal were flared and their great chests lifted and feel with the intensity of their excitement.  Their tails, long and tufted at the end, lashed back and forth
Priest-Kings of Gor, page 18

larl, scarlet I turned to see a stout man-at-arms step to the dais, carrying in his arms, folded in the furs of the scarlet larl, a girl.
Nomads of Gor Page 44

Lart, snow
A mammalian animal with four legs, that is about 10" high, and weighs between 8-12 lbs. It hunts in the sun. The food in the second stomach can be held almost indefinitely. It is filled in the fall and must last the lart through the  winter night, which lasts months. It eats bird's legs and preys on the leem The hunter pulled a pelt from the bundle of furs he carried.  It was snowy white, and thick, the winter fur of a two-stomached snow lart.  It almost seemed to glisten.  The slaver's man appreciated its value.  Such a pelt could sell in Ar for half a silver tarsk.  He took the pelt and examined it.  The snow lart hunts in the sun.  The food in the second stomach can be held almost indefinitely.  It is filled in the fall and last the lart thought the winter night, which lasts months, the number of months depending on the latitude of his individual territory.  It is not a large animal.  It is about ten inches high and weighs between eight and twelve pounds.  It is mammalian, and has four legs.  It eats bird's eggs and preys on the leem, a small arctic rodent, some five to ten ounces in weight, which hibernates during the winter.
Beasts of Gor Page 74

Leem
a small arctic rodent, some five to ten ounces in weight, which hibernates in the winter. Its furs are sold by the Red Hunters

It eats bird's eggs and preys on the leem, a small arctic rodent, some five to ten ounces in weight, which hibernates during the winter.
Beasts of Gor Page 74

The hunter drew forth from the bundle of furs two tiny pelts of the leem.  These were brown, the summer coats of the animals.
Beasts of Gor Page 74-75

Long Tailed Porcupine

In the second level, that of the canopies, is found an incredible variety of birds, warblers, finches, mindars, the crested lit and the common lit, the fruit tindel, the yellow gim, tanagers, some varieties of parrot, and many more. Here, too, may be found snakes and monkeys, gliding urts, leaf urts, squirrels, climbing, long tailed porcupines, lizards, sloths, and the usual varieties of insects, ants, centipedes, scorpions, beetles and flies, and so on.
Explorers of Gor  page 311-312 Monkey

monkey, guernon
found in the jungle along the Ua river; recognized by their chattering sound. Trees surrounded us. Overhead bright jungle birds flew. We could hear the chattering of guernon monkeys about.
Explorers of Gor Page 307

In the lower portion of the canopies, too can be found heavier birds, such as the ivory billed woodpecker and the umbrella bird. Guernon monkeys, too, usually inhabit this level. In the ground zone, and on the ground itself, are certain birds, some flighted, like the hook-billed gort, which preys largely on rodents, such as ground urts, and insectivorous whistling finch, and some unflighted, like the grub borer and lang gim.
Explorers of Gor Pages 311-312

monkey, noctural jit
a simian mammal which inhabits the rain forests inland of Schendi

In the lower branches of the ground zone may be found, also, small animals, such as tarsiers, nocturnal jit monkeys, black squirrels, four-toed leaf urts, jungle varts and the prowling solitary giani, tiny, cat-sized panthers, not dangerous to man. On the floor itself are also found several varieties of animal life, in particular marsupials, such as the armored gatch, and rodents, such as slee and ground urts. Several varieties of tarsk, large and small, also inhabit this zone. More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor  page 311-312

Panthers

panther, jungle
Less dangerous to man than the northern variety inhabitant of the rain forest. On the jungle floor, as well, are found jungle larls and jungle panthers, of diverse kinds, and many smaller catlike predators. These, on the whole however, avoid men. They are less dangerous in the rain forest, generally,  than in the northern latitudes. I do not know why this should be the case.   Perhaps it is because in the rain forest food is usually plentiful for them, and, thus, there is little temptation for them to transgress the boundaries of their customary prey categories. They will, however, upon occasion, particularly  if provoked or challenged, attack with dispatch. Conspicuously absent in  the rain forests of the ua were sleen.
Explorers of Gor  page 311-312

panthers, yellow

Bila Hurmua, indeed, had been an extremely large man, and long armed. He had sat upon a royal stool, of black, lacquered wood, mounted on the  crossed, tied, horns of kailiauk. His arms and legs had been bare, and they had glistened from oil. He had worn armlets and bracelets, and anklets, of gold. He had worn at his loins the pelts of the yellow panther. He wore, too, the teeth of his beast as a necklace.
Explorers of Gor  page 93

Qualae
Small three toed mammals, usually dun colored and having a stiff brushy mane of black hair. As the tarn passed, it scattered into a scampering flock of tiny creatures, probably the small,
three-toed mammals called qualae, dun-coloured and with a stiff brushy mane of black hair.
Tarnsman of Gor. Page 142

and these are often used for hunting light game, such as the brush-maned, three-toed Qualae
Raiders of Gor, page 4

Slee
a rodent which inhabits the ground zone of  the rainforests inland of Schendi.

On the floor itself are also found several varieties of animal life, in particular marsupials, such as the armored gatch, and rodents, such as slee and ground urts. Several varieties of tarsk, large and small, also inhabit this zone. More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor Pages 311-312 Sleen
The deadly hunting dog of Gor, sorta like a cross between a weasel and a Komodo dragon furred, with fangs and doubled rowed sharp teeth. 6 legged and tenacious they can track a trail days or weeks old as if it were fresh, rending and killing the object of the hunt. Sleen are pack animals and cared for only by their  Masters so that they are not befriended by the slave who may try to escape. Then I saw it, on its six short legs, undulate across the road, like a furred lizard, its pointed, whiskered snout swaying from side to side testing the wind.........It was indeed a young sleen, not more than eight feet long, and it lacked the patience of an older animal. Its attack, if it should detect my presence, would be noisy, a whistling rush, a clumsy  squealing charge. It glided away into the darkness, perhaps not fully convinced that it was not alone, a young animal ready to neglect and overlook those slight traces that can spell the difference between  death and survival in Gor’s brutal and predatory world.
Outlaw of Gor, Pages 34 - 35

 I had hardly moved another step when in a flash of lightning, I saw the sleen, this time a fully grown animal, some nineteen or twenty feet long, charging toward me, swiftly, noiselessly, its ears straight against its pointed head, its fur slick with rain, its fangs bared. Its wide nocturnal eyes bright with the lust of the kill. With an eagerness and a lust that matched that of the beast itself, I rushed forward in the darkness and when I judged its leap I lunged forward with the broad-headed spear of Gor, my arm felt wet  and trapped, and was raked with fangs and I was spun as the animal squealed with rage and pain and  rolled on the road. I withdrew my arm from the weak, aimlessly snapping jaws.
A shudder involuntarily shook me, though I do not know if it was due to the cold and the rain at the sight of the long, furred lizard like body that lay at my feet.
Outlaw of Gor, Pages 36-37

"The sleen is Gor's most perfect hunter."
Hunters of Gor, page 156

sleen, forest (black or brown)
It is long, up to 20 feet, sinuous, black or brown in color. It resembles a lizard, except it is furred and mammalian.  In its attack frenzy it is one of the most dangerous animals on Gor. "There are many varieties of sleen, and most varieties can be, to one extent or another,
domesticated. The two most common sorts of trained sleen are the smaller, tawny prairie
sleen, and the large, brown or black forest sleen, sometimes attaining a length of twenty
feet. In the north, I am told the snow sleen has been domesticated. The sleen is a dangerous
and fairly common animal on Gor, which has adapted itself to a variety of environments. There is even an aquatic variety, called the sea sleen, which is one of the swiftest and most dreaded beasts in the sea."
Slave Girl of Gor, page 185

"Sleen are used for a multitude of purposes on Gor, but most commonly they are used for
herding, tracking, guarding and patrolling. The verr and the bosk are the most common
animals herded; tabuk and slave girls are the most common animals tracked; the uses to
which the sleen is put to guarding and  patrolling are innumerable; it is used to secure
borders, to prowl walls and protect camps; it may run loose in the streets after curfews...."
Slave Girl of Gor, page 186

sleen, gray
said to be Gor's finest tracker, this six legged sleen is a furred mammal with silver gray fur.  It has an agile, sinuous body, thick as a drum and is 14-15 feet long.  The gray sleen has a  broad triangular head and a huge jaw with two rows of fangs and a dark tongue.  It's widely set eyes have slit-like pupils.  As is true for all sleens, it has six legs.  This breed is relentless and tenacious.  It can follow a scent that is weeks old for a thousand pasangs. "Keep your legs apart," he said. "It is a gray sleen, I raised from a whelp. Ah, greetings, Borko! How are you, old fellow!"
I would have screamed and reared up, but I was thrust back, helpless, half strangled, scarcely able to utter a sound, to the step.  So our masters can control us by our collars.  To my terror, then, pushing over my body, to thrust its great jaws and head, so large, I could scarcely have put my arms about them, into the hands and arms of my master, was an incredible beast.  It had an extremely agile, active, sinuous body, as thick as a drum, and perhaps fourteen or fifteen feet long.  It might have weighed a thousand pounds.  Its broad head was triangular, almost viperlike, but it was furred.  The thing was mammal, or mammalian.  Its eyes now had pupil like slits, like those of a cat in sunlight.  So quickly then might its adaptive mechanisms have functioned.  About its muzzle were gray hairs, grayer then the silvered gray of its fur.  It had six legs.
Dancer of Gor Pages 160 sleen, hunting
the hunting sleen is a hunter of men and slaves.  It is 20 feet in length and weighs eleven hundred pounds. This domesticated forest sleen is double-fanged and six-footed.  It's tail tends to switch back and forth, getting rigid, as it hunts, it's ears flatten against it's head just prior to it's final 'charge' attack on it's prey. The animal was some twenty feet in length, some eleven hundred pounds in weight, a forest sleen, domesticated.  It was double fanged and six-legged.  It crouched down and inched forward.  Its belly fur must have touched the tiles.  It wore a leather sleen collar but there was no leash on the leash loop.
I had thought it was trained to hunt tabuk with arches but it clearly was not tabuk it hunted now.
I knew the look of a hunting sleen, It was a hunter of men.
It swiftly inched forward, then stopped.
When in the afternoon, I had seen it in its cage, with its trainer, Bertram of Lydius, it had not reacted to me, other then as to the other observers.  It had not then, I knew, been put on my scent.
It crept forward.
I did not think it had been loose from its cage long, for it would take such a beast, a sleen, Gor's finest tracker, only moments to make its way silently through the halls to this chamber.
The beast did not take its eyes from me.
I saw its four hind legs begin to gather under it.
Its breathing was becoming more rapid.  That I didn't move puzzled it.
It then inched forward another foot.  It was now with critical attacking distance.
I did nothing to excite it.
It lashed its tail back and forth.  Had it been longer on my scent I think I might have had less time for its hunting frenzy would have been more upon it, a function in part of the secretions of certain glands.
Very slowly, almost imperceptibly, I reached toward the couch and seized one of the great furs in my right hand.
The beast watched me closely.  For the first time it snarled, menacingly.
Then the tail stopped lashing, and became almost rigid.  Then the ears lay back against its head.
It charged scratching and scrambling, slipping suddenly, on the tiles.  The girl screamed.  The cast fur, capelike, shielding me, enveloped the leaping animal.  I leaped to the couch and rolled over it, and bounded to my feet.  I heard the beast snarling and squealing, casting aside the fur with an angry shaking of its body and head.  Then it stood, enraged, the fur torn beneath its paws, snarling and hissing.
Beasts of Gor  Pages 12-13

"Borko," he said, "is a seasoned hunting sleen.  Even to strangers he would bring a hundred times what you would bring in the market."
Dancer of Gor Pages 161

"The sleen," he said, "and especially the gray sleen, is Gor's finest tracker.  Its relentless, tenacious tracker.  It can follow a scent that is weeks old, for a thousand passangs."
Dancer of Gor Pages 161

sleen, prairie (tawny)
the prairie sleen is tawny in color, and are smaller than the forest sleen, but quite as unpredictable and vicious. Domesticated prairie sleen are used for hunting and nocturnal herd sleen are used as shepherds and sentinels. They are released from their cages responding only to the voice of their master.

"There are many varieties of sleen, and most varieties can be, to one extent or another,
domesticated. The two most common sorts of trained sleen are the smaller, tawny prairie
sleen, and the large, brown or black forest sleen, sometimes attaining a length of twenty
feet. In the north, I am told the snow sleen has been domesticated. The sleen is a dangerous
and fairly common animal on Gor, which has adapted itself to a variety of environments. There is even an aquatic variety, called the sea sleen, which is one of the swiftest and most dreaded beasts in the sea."
Slave Girl of Gor, page 185

"I saw a pair of prairie sleen, smaller than the forest sleen but quite as unpredictable and
vicious, each about seven feet in length, furred, six-legged mammalian, moving in their
undulating gait, with their viper's heads moving from side to side continually testing the winds"
Nomads of Gor, page 2

sleen, sand the southern kaiila viviparous, but the young, within hours after birth, hunt by instinct; the mother delivers the young in the vicinity of game; whereas there is game in the Tahari, birds, small mammals, and occasional sand sleen, and some species of tabuk, it is rare;

Sloth In the second level, that of the canopies, is found an incredible variety of birds, warblers, finches, mindars, the crested lit and the common lit, the fruit tindel, the yellow gim, tanagers, some varieties of parrot, and many more. Here, too, may be found snakes and monkeys, gliding urts, leaf urts, squirrels, climbing, long tailed porcupines, lizards, sloths, and the usual varieties of insects, ants, centipedes, scorpions, beetles and flies, and so on.

Tabuk (also called Golden Gorean Antelope... see below)
a kind of antelope, being yellow in color and having a single horn. They have a sweet tasting meat.

More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor page 312

Gripped in the talons of the tarn was the dead body of an antelope, one of the one-horned, yellow
antelopes called tabuks that frequent the bright Ka-la-na thickets of Gor.
Tarnsman of Gor. Pg 146

golden gorean antelope In the very low case, on the floor of which apparently grew real grass, I saw a pair of shaggy, long-horned bosk grazing, and in the same case but in a different corner was a small head, no more than five adult animals, a proud male and four does, of tabuk, the single-horned, golden Gorean antelope. When one of the does moved I saw that moving beside her with dainty steps were two young tabuk, the first I had ever seen, for the young of tabuk seldom venture far from the shaded, leafy bowers of their birth in the tangled Ka-la-na thickets of Gor. Their single horns were little more than velvety stubs on their foreheads and I saw that their hide, unlike that of the adults, was a mottled yellow and brown. When one of the attendant Muls happened to pass near the case the two little tabuk instantly froze, becoming almost invisible, and the mother, her bright golden pelt gleaming, began to prance away from them, wile the angry male lowered his head against the Mul and trotted in a threatening manner to the plastic barrier.
Priest-Kings of Gor Page 191 tabuk, northern "They were northern tabuk, massive, tawny and swift; many of them ten hands at the shoulder, a quite different animal from the small, yellow-pelted antelope-like quadruped of the south. On the other hand, they too were distinguished by the single horn of the tabuk.  On these animals, however, that object, in swirling ivory, was often, at its base, some two and one half inches in diameter, and better than a yard in length. A charging tabuk, because of the swiftness of its reflexes, is quite a dangerous animal."
Beasts of Gor, page 152

The red hunters lived as nomads, dependent on the migrations of various types of animals, in particular the northern tabuk and four varieties of sea sleen.  Their fishing and hunting were seasonal, and depended on the animals.  Sometimes they managed to secure the northern shark, sometimes even the toothed Hunjer whale or the less common Karl whale, which was a four-flucked, baleen whale.
Beasts of Gor Page 36

Tarsiers In the lower branches of the ground zone may be found, also, small animals, such as tarsiers, nocturnal jit monkeys, black squirrels, four-toed leaf urts, jungle varts and the prowling solitary giani, tiny, cat-sized panthers, not dangerous to man. On the floor itself are also found several varieties of animal life, in particular marsupials, such as the armored gatch, and rodents, such as sleens and ground urts. Several varieties of tarsk, large and small, also inhabit this zone. More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor  page 311-312

Tarsk
animal akin to the Urth pig, having a bristly mane which runs down its spine to the base of the tail

"if I were lucky, a slice of roast tarsk, the formidable six tusked wild boar of Gor’s temperate
forests."
Assassin of Gor, page 87

"I thought of the yellow Gorean bread, baked in the shape of round, flat loaves, fresh and hot; my mouth watered for a tabuk steak or, perhaps, if I were lucky, a slice of roast tarsk, the formidable six-tusked wild boar of Gor's temperate forests."
Outlaw of Gor, page 76

"Watch out!" I said.
The tarsk, a small one, no more than forty pounds, tusked, snorting, bits of leaf scattering behind it, charged. It swerved, slashing with its curved tusks, and I only managed to turn it aside with the point of the raider's spear I carried, one of four such weapons we had had since our brief skirmish with raiders, that in which we had obtained our canoe, that which had occurred in the marsh east of Ushindi. It had twisted back on me with incredible swiftness. The blond-haired barbarian screamed.  I thrust at it again. Again it spun and charged. Again I thrust it back. there was blood on the blade of the spear and the animal's coat was glistening with it. Such animals are best  hunted from the back of kaiila with lances, in the open.  They are cunning, persistent and swift. The giant tarsk, which can stand ten hands at the shoulder, is even hunted
with lances from tarnback.

Tharlarion

"Look!" said Ayari, pointing off to the left. There we saw a tharlarion, sunning itself on a bar. As we neared it, it slipped into the water and swam away.
Explorers of Gor...page 282

tharlarion, broad
Sluggish tharlarion used as draft animals, herbivorous " The high tharlarions, unlike their draft brethren, the slow-moving, four-footed broad tharlarions, were carnivorous."
Tarnsman of Gor, page 125

"Behind them, stretching into the distance, came a long line of broad tharlarions, or the four-footed draft monsters of Gor. These beasts, yoked in braces, were drawing mighty wagons, filled with merchandise protected under the lashings of its red rain-canvas."
Tarnsman of Gor, page 118

tharlarion, high
Agile tharlarion used as a mount for riding, like T. rex, they have very short, almost useless, forelegs The ringing of the tharlarion’s shod claws on the road grew louder.
In a minute the rider appeared in view - a fine bearded warrior with a golden helmeet and a tharlarion lance. He drew the riding lizard to a halt a few paces from me. He rode the species of tharlarion called high tharlarion, which ran on its two back feet in bounding strides. Its cavernous mouth was lined with long, gleaming teeth. Its two small ridiculously disproportionate forelegs dangled absurdly in front of its body.
Tarnsman of Gor Page 115

"When the high tharlarion moves slowly, its stride is best described as a proud, stalking movement, each great clawed foot striking the earth with a measured rhythm. When urged to speed, however, the high tharlarion bounds, in great leaping movements that carry it twenty paces at a time."
Tarnsman of Gor, page 125

tharlarion, hunting

"It was a small, hunting Tharlarion, controlled by bit and bridle. The large upright Tharlarion, or war Tharlarion, are guided by voice commends and the blows of spears. The man put the knife in his teeth and, fiercely, smote the Tharlarion. It grunted and, splashing, fled from the water, running in its birdlike gait across
the fields."
Beasts of Gor Page 125 tharlarion, land
land dwelling tharlarion used for towing.  The land tharlarion can swim, though not as efficiently as the river tharlarion. Those approaching were drawn by land tharlarion, plodding on log roads along the edges of the river.  The land tharlarion can swim a barge across the river, but he is not as efficient as the vast river tharlarion.
Captive of Gor Page 81 tharlarion, racing
these high tharlarions are bred and registered for racing.  Unlike the animals used as cavalry, these are chosen from 'medium class' tharlarion, being smaller and lighter.  Famous bloodlines include Venetzia, Toraii, and Thalonian.
Book 25: Magicians of Gor, page 290

tharlarion, war (or upright)

"It was a small, hunting Tharlarion, controlled by bit and bridle. The large upright Tharlarion, or war Tharlarion, are guided by voice commends and the blows of spears. The man put the knife in his teeth and, fiercely, smote the Tharlarion. It grunted and, splashing, fled from the water, running in its birdlike gait across
the fields."
Beasts of Gor Page 125

Urt
Sorta like a  reptilian rat, the size of a terrier, has three rows of teeth, two tusks, and two horns "The urt is a loathsome, horned Gorean rodent; some are quite large, the size of wolves or ponies, but
most are very small, tiny enough to be held in the palm of one hand."
Nomads of Gor, page 125

urt, brush I saw a tiny brush urt scurry past.
Hunters of Gor, page 106 urt, canal
rapid moving water mammal living along canals; particularly found in Port Kar. "I heard one of the giant canal urts twist in the water somewhere beneath me."
Raiders of Gor, page 119 urts, forest
nocturnal animal living in the forests, hunted by the hook-billed night crying fleer. "Over her shoulders she had two small, furred animals, hideous forest urts, about the size of cats, and in her left hand she carried four small, green-and-yellow-plumaged birds."
Captive of Gor, page 237

"Their catch, returned to the Tesephone, in a cage, covered with canvas, carried on the back of Thurnus, had been six, rather large forest urts, about the size of tiny dogs."
Hunters of Gor, page 38

urt, giant
fat, sleek, and white, it has 3 rows of needle-like white teeth and 4 horns. I smelled the wet fur of the animal, a rodent of some kind, the smells of its den, the soiled straw. For some time the animal, moving backwards, its prey seized in its jaw, scrambled through the tunnel. It dragged me in a series of quick, vicious jerks through the tunnel, scraping me on its stone walls, lacerating me, ripping my tunic. It was a giant urt, fat, sleek and white; it bared it three rows of needle like white teeth at me and squealed in anger; two horns, tusks like flat crescents curved from its jaw; another two horns, similar to the first, modifications of the bony tissue forming the upper ridge of the eye socket, protruded over those gleaming eyes that seemed to feast themselves upon me, as it waiting the permission of the keeper to hurl itself on its feeding trough. Its fat body trembled with anticipation. The whip cracked again, and another command was uttered, and the animal; its long hairless tail lashing in frustration, slunk into another tunnel.

A small tree-dwelling rodent which inhabits the rainforests inland of Schendi In the second level, that of the canopies, is found an incredible variety of birds, warblers, finches, mindars, the crested lit and the common lit, the fruit tindel, the yellow gim, tanagers, some varieties of parrot, and many more. Here, too, may be found snakes and monkeys, gliding urts, leaf urts, squirrels, climbing, long tailed porcupines, lizards, sloths, and the usual varieties of insects, ants, centipedes, scorpions, beetles and flies, and so on.

a small animal which inhabits the floor of the rainforests inland of Schendi. In the lower portion of the canopies, too can be found heavier birds, such as the ivory billed woodpecker and the umbrella bird. Guernon monkeys, too, usually inhabit this level. In the ground zone, and on the ground itself, are certain birds, some flighted, like the hook-billed gort, which preys largely on rodents, such as ground urts, and insectivorous whistling finch, and some unflighted, like the grub borer and lang gim.

urt, tree
a small tree-climbing rodent found in the rainforests inland of Schendi In the level of the emergents there live primarily birds, in particular parrots, long-billed fleers, and needle-tailed lits. Monkeys and tree urts, and snakes and insects, however, can also be found in this highest level
Explorers of Gor  page 311-312

Verr
a mountain goat indigenous to the Voltai Mountains, wild, agile, ill tempered, with long hair and spiraling horns, source of a form of wool, it milk is potable, as well as being used for cheese "In the cafes I had feasted well. I had had verr meat, cut in chunks and threaded on a metal rod, with slices of peppers and larma, and roasted; vulo stew with raisins, nuts, onions and honey; a kort with melted cheese and nutmeg; hot Bazi tea, sugared and later, Turian wine."
Tribesmen page 37

"...perhaps after the agile and bellicose Gorean mountain goat, the long haired, spiral horned verr..."
Tarnsman of Gor, page 147

"The verr was a mountain goat indigenous to the Voltai. It was a wild, agile, ill tempered beast,
long-haired and spiral-horned. Among the Voltai crags it would be worth one's life to come within twenty yards of one."
Priest-Kings of Gor, page 63

"I passed fields that were burning, and burning huts of peasants, the smoking shells of Sa-Tarna granaries, the shattered, slatted coops for vulos, the broken walls of keeps for the small, long-haired domestic verr, less belligerent and sizable than the wild verr of the Voltai ranges."
Nomads of Gor, page 10

"Kaiila and verr are found at the oases, but not in great numbers. The herds of these animals are found in the desert. They are kept by nomads, who move them from one area of verr grass to another, or from one water hole to another..."
Tribesmen of Gor, page 37

"Behind them came another of their caste, leading two milk verr which he had purchased."

Zeder
a small, sleen like, carnivorous mammal which inhabits the rainforests inland of Schendi, esp. along the Ua River, grows to c. 2' and weighs 8-10 lbs; is diurnal, can swim very well, & builds a stick and mud nest in the branches of a tree, where it spends  the night

there is, however, a sleenlike animal, though much smaller, about two feet in length and some eight to ten pounds, in weight, the zeder, which frequents the Ua and her tributaries. It knifes through the water by day and, at night, returns to its nest, built from sticks and mud in the branches of a tree overlooking the water
