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.

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.
