DESCRIPTIONS OF VENOMOUS SNAKES

VIPERIDAE

E-12. The viperidae, or true vipers, usually have thick bodies and heads that are much wider than their necks (Figure E-4). However, there are many different sizes, markings, and colorations.

E-13. This snake group has developed a highly sophisticated means for delivering venom. They have long, hollow fangs that perform like hypodermic needles. They deliver their venom deep into the wound.

E-14. The fangs of this group of snakes are movable. These snakes fold their fangs into the roof of their mouths. When they strike, their fangs come forward, stabbing the victim. The snake controls the movement of its fangs; fang movement is not automatic. The venom is usually hemotoxic. However, there are several species that have large quantities of neurotoxic elements, thus making them even more dangerous. The vipers are responsible for many human fatalities around the world.
