What's the difference between a legless lizard and a snake? Unlike snakes, legless lizards have moveable eyelids, scales on the belly and ability to reject the tail in the case of danger. Snakes can't hear sound very well, and instead 'hear' through the lower part of their snakes are certainly one of the oldest limbless reptiles, going back at least 120 million years, but that isn't necessarily the reason for their success.
