	Pit viper - Wikipedia, the free encyclopedia
		Pit Vipers (sometimes called crotalines) are mostly New World vipers found in North, Central and South America; along with approximately 69 species occuring in Southeast Asia, Malaysian Archipelago, the Caspian region of Europe, China and Japan.
		Depending on the taxonomist, Pit Vipers may be treated as a subfamily (Crotalinae) of the viper family Viperidae (with "true vipers" or pitless vipers in the subfamily Viperinae), or as a family of their own, Crotalidae.
		Pit Vipers are a versatile group, with members found in habitats ranging from parched desert (e.g., rattlesnakes) to rainforests (e.g., fer-de-lance) and even aquatic settings (e.g., the water moccasin).

		Pit vipers, along with several of their snake cousins, marry two senses to better locate prey at night: sight and a heat-detecting ability.
		Deep pits, which lie on each side of the snake's face between the nostril and the eye, are capable of sensing the warmth given off by a human hand held a foot away.
		Each pit has its own "field of vision" which overlaps slightly with the other, so that the pair work stereoscopically in the same way that eyes do. Heat and visual data are sent, via the optic nerve, to the pit-viper's brain, where the two types of data are transposed into a single image.

		The pit vipers are closely related to the true vipers and are usually classified as a subfamily, Crotalinae, of the viper family, Viperidae; many authorities, however, consider the pit organs--which are lacking in the true vipers--so significant that they regard the pit vipers as a distinct family, Crotalidae.
		The pit has a thermoreceptor function and is sensitive to infrared radiation; it is capable of responding to changes in temperature of only fractions of a degree.
		The pit vipers are a successful group that has adapted to a wide range of environmental conditions.
