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.
Snake venoms vary dramatically from species to species, but they have one thing in common: Every one of them is an extremely complex composition, made from sometimes thousands of different proteins and enzymes, each with a specific function. Venoms can be roughly divided into three main groups: cytotoxins, neurotoxins and hemotoxins. But the lines dividing these groups are fluid, and most species employ a combination of the three. The type of poison and how fast it works is adapted to the snake's lifestyle and that of its prey. Sea snakes, for instance, have extremely fast-acting venom.
