Venomous Fangs

The fangs of dangerous, venomous snakes are thin, sharply pointed and hollow.

Venom, is produced in glands which can be found behind the eyes in the side of the head.

The venom passes from the glands through a duct into a canal running down inside of the fang to its tip.

Muscles around the venom glands contract during a bite and control the amount of venom injected.

Large amounts of venom are injected by some snakes as they bite and hold on to their prey with a chewing action.

The more flexible the fangs are (ie their ability to rotate) the more venomous the snake can be.

New fangs are grown from time to time during the life of a snake.
