Pit vipers and most boas and pythons have a pair of large pits between the eyes and nostrils, which are very sensitive to temperature. By comparing the messages received on the right and left sides, they are able to tell exactly where their warm-blooded prey is. There are four types of motion that snakes use to get around. Which one is used depends on the type of snake, their habitat, and their muscular design. All snakes are carnivores.
Some snakes eat frogs, other snakes, fish, or snails.
The jaws of snakes are specialized to help them eat large prey. Their upper and lower jaws can move independently of one another. When swallowing prey, the two halves of the lower jaw move out of their sockets. Their teeth are pointed inward, which helps them to move the prey into their bellies. When they are finished, snakes yawn to put the jawbones back into place.
