"Do not so violate the privacy of a girls dream!" she begged.
"You have no privacy," I said. "You belong to me."
"Am I not to be permitted the least vestige of my pride?" she asked.
"No," I told her.
"I shall now perform for my master," she said.
"Do so," I said, "and precisely, in each and every detail, as in your dream."
Yes, my master," she said. she looked at me. "Remember," she said, "that I was forced to do this, that I not be hurled to the waiting jaws of crocodiles, beasts much like river tharlarion. That I not suffer so horrible a fate I knew that I must please him well, and as the slave which I had
now been proven to be."

Eel

"Clitus, too, had brought two bottles of Ka-la-na wine, a string of eels, cheese of the Verr and a sack of red olives from the groves of Tyros."
Raiders of Gor, page 114

"I was only dimly conscious of the wetness of my back.  Then something wet and heavy,
slithering; leapt upward out of the water, and splashed back.  My leg felt stinging.  It had not
been able to fasten its jaws on me.  I looked downward.  Two more heads, tapering, menacing, solid, were emerged from the water, looking up at me.  Then, streaking from under the water, suddenly breaking its surface, another body, some four feet in length, about eight or ten pounds in weight, leapt upward.  I knew that the fastening of those jaws, in a fair bite, could gouge ounces of flesh from a man's body."
Rogue of Gor, page 130

     Many estates, particularly country estates, have pools in which fish are kept. Some of these pools contain voracious eels, of various sorts, river eels, black eels, the spotted eels, and such, which are Gorean delicacies. Needless to say a bound slave, cast into such a pool, will be eaten alive.

bint (march eel) Kisu dropped it back in the water.  "I do not want my blood pinched from it, released in the water," he said. Ayari nodded, shuddering. Such blood might attract the bint, a fanged, carnivorous march eel, or the predatory larger and familiar salt-water grunt of Thassa.

eel, dock
A black freshwater fish, 4' long & weighing 8-10 lbs., carnivorous, they inhabit the shallow waters around the dock and wharves of river ports " When he stood in about a foot of water, among the pilings, near the next wharf, he struck down madly at his legs with his left hand, striking two dock eels from his calf."
Rogue of Gor, page 154

"The dock eels, black, about four feet long, are tenacious creatures.  They had not relinquished their hold on the flesh in their jaws when they had been forcibly struck away from the leg, back into the water."

Golden Hith
a rare Gorean python, so large, it would be difficult for a man to encircle it's body with his arms. Along  the river, of course, many other species of birds may be found, such as  jungle gants, tufted fishers and ring-necked and yellow-legged waders. Also  in the ground zone are varieties of snake, such as the ost and hith, and numerous species of insects. The rock spider has been mentioned, and termites also. Termites, incidentally, are extremely important to the ecology of the forest. In their feeding they break down and destroy the branches and trunks of fallen trees. The termite  dust,  thereafter, by the action of bacteria, is reduced to humus, and the humus to nitrogen and mineral materials.
Explorers of Gor  page 311

"In another case, somnolent and swollen, I saw a rare golden hith, a Gorean python whose
body, even when unfed, it would be difficult for a full-grown man to encircle with his arms."
Priest Kings of Gor, page 191

Lizard

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.

lizard, water there was a stirring in the water, and I realized the small water lizards of the swamp forest were engaged in their grisly work.
Tarnsman of Gor  Page 84

Idly, with repulsion, I watched the body of the tharlarion in the swamp. As the water lizard had fed, the carcass, lightened, had shifted, rolling in the water. Now, in a matter of minutes, the skeleton was visible, picked clean, the bones gleaming except where the small lizards skittered about on them, seeking a last particle of flesh.
Tarnsman of Gor  Page 85

Mamba
(also see river tharlarion) Large, predatory river tharlarion which inhabits the rivers of the rain forests  inland of Schendi; they have long, log like bodies, with short, powerful legs & a long snout & tail; similar to Earth crocodiles The word "Mamba" in most of the river dialects does not refer to a venomous reptile as might be expected, given it's meaning in english, but, interestingly, is applied rather generally to most types of predatory river tharlarion.  The Mamba people were, so to speak, the Tharlarion people.  The Mamba people ate human flesh.  So, too, does the tharlarion.  It is thus, doubtless, that the people obtained their name.

Ost
Brilliantly colored orange snake of about a foot in length, its venom causes extremely painful death within seconds; the ost of the rain forests inland of Schendi are red with black stripes

ost, banded "The banded ost is a variety of ost, a small, customarily brilliantly orange Gorean reptile. The banded ost is yellowish orange and is marked with black rings.
Assassin of Gor, page 335 ost, ushindi His body was twisted horribly, and contorted. The flesh had turned a blackish orange and, in places, had broken open, the skin peeling back like burned paper. A knife, fallen, lay near him in the pit. About his body, small, nervous, sinuous, crawled tiny snakes, osts. Each of these, startlingly, had tied to it a thin string. there were eight such diminutive reptiles. The strings, fastened behind their heads, led up to a pole at the head of the sleeping platform, where they were tied. A woven basket hung, too, near the foot of the sleeping platform. the ost is usually an orange snake, but these were Ushindi osts, which are red with black stripes. Anatomically, and with respect to toxin, I am told they are almost identical to the common ost.
Explorers of Gor  page 238-239

Salamanders Among the lelts, too, were, here and there, tiny salamanders, they too, white and blind.  Like the lelts, they were, for their size, long bodies, were capable of long periods of dormancy and possessed a slow metabolism, useful in an environment in which food is not plentiful.  Unlike the lelts, they  had long, stemlike legs.  At first I had taken them for lelts, skittering bout the rafts, even to the fernlike filaments at the side of their head, but these filaments, in the case of the salamanders, interestingly, are not vibration receptors but feathery gills, an external gill system.  This system, common in developing animals generally, is retained even by the adult salamanders, who are, in this environment, permanently gilled.  The gills of the lelt are located at the lower sides of it's jaw, not on the side of it's head, as in common open water fish.  The feather gills of the salamanders, it seems allow them to hunt in the same areas as the lelts for the same prey, the vibration effects of these organs being similar, without frightening them away, thus disturbing the water and alerting possible prey. They often hunt in the same areas.  Although this form of salamander possesses a lateral-line set of vibration receptors, like the lelt, it lacked the craneal receptors and it's lateral-line receptors do not have sensitivity of the lelt's.  Following the lelt, not disturbing it, often helps the salamander find prey.  On the other hand, the salamander, by means of it's legs and feet, can dislodge prey inaccessible to the lelt.  The length of the stemlike legs of the salamander, incidentally, help in stalking in the water.  Further they enable the animal to move efficiently, covering large areas without considerable metabolic cost.  In a blind environment, when food is scarce, energy conservation is essential.
Tribesmen of Gor Page 247 Snakes 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

Tharlarion
(also see UI, it's referred to as a winged tharlarion)

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 tharlarion, 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, marsh
inhabitants of the marshes that comprise the delta of the Vosk, similar to crocodile. The delta of the Vosk, for most practical purposes, a vast marsh, an area of thousands of square pasangs, where the Vosk washes down to the sea, is closed to shipping.  It is trackless and treacherous, and the habitat of marsh tharlarion and the predatory UI, a winged lizard with wing-spans of several feet.
Explorers of Gor Page 26

I nodded.  The marsh tharlarion, and river tharlarion, of Gor are, I suspect genetically different from the alligators, caymens and crocodiles of Earth.  I suspect this to be the case because these earth reptiles are so well adapted to their environment that they have changed very little in tens of millions of years.  The march and river tharlarion, accordingly, if descended from such beasts, brought long ago to Gor on Voyages of Acquisition by Priest Kings, would presumably resemble them more closely.
Explorers of Gor Page 326

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.
Magicians of Gor, page 290

tharlarion, river
Extremely large, herbivorous, web footed lizards used by bargemen of the Cartius River to pull barges

A broad, low-sided barge began to back toward the pier.  It had two large steering oars, manned by bargemen.  It was drawn by two gigantic, web footed river tharlarion.  These were the first tharlarion I had seen.  They frightened me.  They were scaled, vast and long-necked.  Yet in the water it seemed, for their bulk, they moved delicately.  One dipped its head under the surface and moments later, the head emerged dripped, the eyes blinking, a silverish fish struggling in the small, triangular-toothed jaws.  It engorged the fish, and turned it small head, eyes now unblinking, to regard us.  They were harnessed to the broad barge.  They were controlled by the bargeman, with a long whipping stick, who was ensonced in a leather basket, part of the harness, slung between the animals.  He would also shout at them, commands, interspersed with florid Gorean profanity, and, slowly, not indelicately, they responded to his cries

tharlarion, rock
A small reptile of the Tahari he was now regarded as much in the same category with the urts that one clubs in the Sa-Tarna sheds, or are pursued by small pet sleen, kept there for that purpose, or with the tiny, six-toed rock tharlarion of southern Torvaldsland, favored for their legs and tails, which are speared by children.
Marauders of Gor Page 152 tharlarion, tiny
similar to those in the swamp forest south of Ar One of the guards, carrying a long, wooden pole, thrust it down, into the water. The water, judging by the pole, must have been about eight feet deep. The other guard, then, thrusting a heavy piece of meat on one of the hooks, to which a rope was attached, held the meat away from the platform and half submerged in the water. Almost instantly there was a frenzy in the water near the meat, a thrashing and turbulence in the murky liquid. I felt
water splashed on my legs, even standing back as I was. Then the guard lifted the roped hook from the water. the meat was gone. Tiny tharlarion, similar to those in the swamp forest south of Ar, dropped, snapping, from  the bared hook. such tiny, swift tharlarion, in their thousands, can take the meat from a kailiauk in an Ehn.

Beasts of Gor Page 125 tharlarion, water It is dangerous to enter the water to make a tether fast because of the predators, that frequent the swamp, but several men do so at a time, one man making fast the tether and the others, with him beneath the surface, protecting him with march spears, or pounding on metal pieces or wooden rods to drive away, or at least to disconcert and confuse, too inquisitive, undesired visitors, such as the water tharlarion or the long bodied, nine gilled marsh shark.

Vart
similar to a bat, it's a flying rodent, blind and carnivorous

"Perhaps most I dreaded those nights filled with the shrieks of the vart pack, a blind, batlike swarm of
flying rodents, each the size of a small dog. They could strip a carcass in a matter of minutes...Moreover, some vart packs were rabid."
Outlaw of Gor, page 26

The Vart is a small, sharp-toothed winged mammal, carnivorous, which commonly flies in flocks
Explorers of Gor  page 36

"Tyros is a rugged island, with mountains. She is famed for her vart caves, and indeed, on that island,
trained varts, batlike creatures, some the size of small dogs, are used as weapons."
Raiders of Gor, page 139

vart, brown "I could, however, recognize a row of brown varts, clinging upside down like large matted fists of teeth and fur and leather on the heavy, bare, scarred branch in their case."
Priest Kings of Gor, page 191 vart, jungle
a relative of the northern vart, it 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 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.
