All snakes are carnivores or meat-eaters. Small snakes eat bugs and
frogs. Larger ones eat fish, birds, mice, and rabbits. They use sharp teeth and strong muscles to catch the prey. If the prey animal is bigger than the snake’s mouth, the snake can dislocate (unhinge) its bottom jaw to fit the big animal in. They repeatedly flick out their narrow, forked tongue, using it to bring odours to a special sense organ in the mouth.
Some snakes (like boas and the anaconda) kill their prey by squeezing it to death. Snakes do not chew their food or even bite it into pieces, they swallow their food whole.
