Vipers - Old World Vipers, Pitvipers

venom snakes prey fangs

Vipers are snakes in the family Viperidae, a group of short-tailed, (usually) stout-bodied snakes with long fangs at the front of the mouth, sited on a short jawbone that can be rotated to bring the fangs from their resting position parallel with the palate to an erect position for striking.

This efficient venom delivery system allows vipers to eat large (and sometimes dangerous) animals without a struggle that might expose them to harm. Vipers make a swift strike in which the long hollow (hypodermic needle-like) fangs inject a strong venom deep into the prey's body. The snakes then wait until the animal dies, tracking it down if necessary, and then calmly swallowing it. The venom also has the effect of initiating digestion even before the prey is swallowed. Many vipers do not find it necessary to eat more than once a month. The venom of these snakes are diverse, being adapted to quickly kill the preferred prey animals of each species.

Vipers are an old and diverse group. They are generally divided into the Old World "true" vipers (Viperinae) and the pit vipers (Crotalinae), which are found in Asia and the Americas.

Anyone who fools around with any species of snake is crazy. The vipers carry a large amount of venom to immobilize their prey. When man interferes or enters their territory, he is asking for trouble. Children have been killed by constrictors raised as pets.

I know that there are people who want to handle venomous (the correct word)snakes, but they should know that handling such creatures is asking for trouble. We should enjoy them in the zoos or in the wild. NOT as pets.
