Snake
The snake is a long, unobtrusive carnivorous reptile in the Serpentes suborder. Like all Squamata species, snakes are vertebrates of amniot ectoterms that are overwhelming overlapping scales. Most snake species have more skulls than their lizard ancestors so it is easy to swallow a bigger victim than his head with a very moving jaw. To cope with the narrow snake body, the pairing organs are arranged in the following-follow, not adjacent, let alone most snakes have only one lung. Some species have pelvic girdles with a pair of vesture paws next to the cloaca. There are also non-legged but not reptile species, the lizard without legs; The difference is that the snake has no eyelid and external ear. The snakes are found alive on every continent, the Pacific Ocean and the Indian Ocean, as well as most smaller terrain - among the exception are some large islands like Ireland and New Zealand, as well as most small islands in the Atlantic Ocean and the middle of the Pacific Ocean.
