Snakes are elongate, legless, carnivorous reptiles in the suborder Serpents that may be distinguished from legless lizards by their lack of eyelids and external ears. Like every squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with a lot of more joints than their lizard ancestors, enabling these phones swallow prey much wider than their heads making use of their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (for instance kidneys) appear one out of front in the other as an alternative to side-by-side, and the majority just have one functional lung. Some species retain a pelvis that has a pair of vestigial claws on spare on both on the cloaca.
