Snakes are legless carnivorous reptiles which lack eye lids and external ears. They have loosely attached jaws which enable them to swallow prey larger than the size of their heads. Very often they only have one lung and all other organs lie one behind the other. A large portion of snakes are non venomous, however there are several whose venom is lethal to humans.
