The venom for snakes is used to immobilize prey and then to be able to eat them. The fangs are used to bite and then the venom is injected. Approximately 375 species of snakes are able to create venom.
Vipers (Viperidae) are a group of snakes known for their long fangs and venomous bite. Vipers include true vipers, bush vipers, rattlesnakes, pit vipers, adders and night adders. The fangs of vipers are long and hollow and enable the snake to inject venom into animals that it bites. Venom is produced by and stored in glands located at the back of the snake's upper jaw. When the snake's mouth is closed, the fangs recede into a thin membrane and fold against the roof of the snake's mouth.
