A snake is a legless reptile belonging to the suborder Serpentes. They have elongated bodies covered in scales and can be found in various habitats, including forests, deserts, and oceans. Snakes are cold-blooded and rely on their environment to regulate their body temperature. They are known for their unique method of locomotion, using their muscles and scales to slither. Snakes are carnivorous and primarily feed on small animals, such as rodents, birds, and frogs. They have specialized jaws that allow them to swallow prey whole. Some species are venomous, using their venom to immobilize prey, while others constrict their victims.
