How do they eat? Catching and eating food is a very specialised activity. Snakes don’t have claws with which to grab, tear or hold their food, and they are unable to chew because their teeth and hinged jaws aren't designed for the purpose to chew their food. Snakes are able to dislocate it’s upper and lower jaw and separate the two sections of its lower jaw. This allows it to move each jaw by itself, and spread open it’s head and throat to swallow the prey much larger than the usual diameter of it’s mouth. Digestion takes place in the stomach, with the aid of very strong digestive juices. Unlike endothermic animals, a snake's food digestion rate is influenced by external temperatures.
What do they eat? § It depends on what kind of snake it is, and Snakes eat insects like termites, mice, rats, frogs, fish, and even other snakes and reptiles Some snakes eat eggs, swallowing the egg whole, crushing it with its powerful muscles, and later regurgitating the eggshell. Larger snakes, such as the anaconda which drops on its prey from the branches of a tree, will eat monkeys, pigs, goats, and even deer. Snakes eat their prey whole and are able to consume prey three times larger than the diameter of their head because their lower jaw can separate from the upper jaw. To keep prey from escaping, snakes have rear-facing teeth that hold their prey in their mouths. Venomous snakes inject their prey with venom, while constrictors squeeze their prey. They do not need to hunt everyday. Anacondas and pythons can survive for up to a year without food after feeding. Snakes hunt mostly at night.

So this means that snakes are predators to rodents and most snakes are carnivores. A snake’s success is their ability to change their diet in different seasons, eating whatever they can find.
