When it gets too hot, they slip back into the water and cool off before sunbathing again in the cooler afternoon sun. Alligators are found in America and China. They look very much like crocodiles, except that in crocodiles, the fourth tooth of the lower jaw is clearly visible even when the mouth is shut. Snakes Adders are venomous snakes found in Europe. They lie in wait for their prey, bite it, wait for it to die and then swallow it.
Snakes are long, thin, legless reptiles.
Most live in warmer regions, but some adders live inside the Arctic Circle. With no legs to grasp victims, snakes kill their prey in other ways. Constrictors such as pythons wrap themselves around the animal and stop it breathing. The venom is made in special salivary glands and injected into victims through fangs - though a few snakes can spit venom. Snakes hunt their prey by sight, sound or smell.
