Eating habits of snakes
There is a huge variety of food which is consumed by the snakes. They live on termites, birds, amphibians like frogs and even up to small deer. The anacondas are notorious for consuming the whole humans as well. The snakes do not chew their food because they do not have teeth. They always consume their food by swallowing it as a whole and then digest it with the help of strong enzymes in the stomach. The snakes can swallow the prey three times the size of their head because there is no connection between the upper and lower jaw and they can both separate widely. There are no teeth for chewing but there are rear facing teeth in the mouth of snakes which prevent the prey form escaping their mouth.
The venomous snakes have got another weapon in the form of venom. They use the venom to paralyze and kill the prey. Similarly the constrictors present in their saliva help to squeeze the prey. Snakes are nocturnal and heat at night. Snakes usually do not hunt every day. Once they hunt and eat their prey, they can even survive for up to a year like python and anaconda.
