Unlike the cobras and vipers, whose fast-acting venom can knock out or kill an animal in moments, the colubrids produce venom that is not as strong and usually takes many minutes to work. When a colubrid bites down on a prey animal, this venom, or poison, trickles into the prey animal the venom slows down, knocks out, or kills the animal, which the colubrid then eats. These glands squeeze out a mixture of chemicals that, in some species, oozes through enlarged back teeth, known as rear fangs. Most colubrids also have glands, or groups of cells, behind each eye. Most have wide scales on their bellies and, usually, nine large scales on the tops of their heads. Despite the many differences among the snakes in this family, colubrids share a few features. These snakes come in many sizes, shapes, and colors. The colubrids (KAHL-yuh-bruhds) make up the largest group of snakes they include almost 75 percent of all the world's snake species, or types of snakes.
