Vipers - Viperidae

The vipers form a well defined and advanced family of snakes found throughout much of the world but absent from Madagascar and Australia . Their most distinctive characteristic is a pair of shortened maxillae to each of which is attached a single long fang . Each maxilla is hinged so that the fangs can be folded back when not in use . The fangs have an enclosed canal through which venom is forced . Vipers are typically short and stocky with broad heads . The scales are usually heavily keeled (except night adders , in which they are smooth) and the head is covered with small irregular scales : the night adder is , again , an exception and there are a few others . They are mainly terrestrial or arboreal but there are semi-aquatic . They may be diurnal or nocturnal , depending largely on their distribution : several species come from cold environments and ere then mainly diurnal . Many are well-camouflaged snakes that ambush their prey , which consists mostly of warm-blooded vertebrates , although some also eat reptiles and a few partly insectivorous . most species are viviparous but a few lay eggs . The family is divided into four subfamilies : the Viperinae and the Crotalinae each have many species whereas the Azemiopinae and Causinae have few . The Crotalinae are unique among snakes in possessing a pair of large heat-sensitive pits between the eye and the nostril .


RattleSnake's Rattles

The rattle on the tail of rattlesnakes , genera Crotalus and Sistrurus , is formed from the successive remains of the scale covering the extreme tip of the tail . In most snakes , this scale is conical and the epidermis covering it comes away with the rest of the shed skin . In rattlesnakes , however , the terminal scale is shaped like an hour-glass , with a constriction somewhere around its centre line . After the first shed , the skin around this terminal scale becomes thicker than normal . When the young snake sheds for the second time , this scale is torn away from the old skin , because it is held in place by the constriction . Now a new skin is formed around the tip of the tail but it shrinks away from the piece of old skin so that it is attached only loosely . When the snake sheds again , the second layer is prevented from coming away , the tail has two segments , one inside the other , and the cyle starts over again . Eventually a number of segments are built up , the oldest towards the end of the tail and the freshest towards its base . Each segment , then , represents a shed skin , but although the snake may shed four or more times each year , rattles that consist of more than six or seven segments are rare because the material is brittle and the tip , including the button , is usually broken off , leaving only the most recently formed rings .
