Pygopodidae (commonly known as legless lizards, snake-lizards, or flap-footed lizards) is a family of squamates with reduced or absent limbs, and are a type of gecko. There are at least 35 species in two subfamilies and eight genera. They have unusually long, slender bodies, giving them a strong resemblance to snakes. Like snakes and most geckos, they have no eyelids, but unlike snakes, they have external ear holes and flat, unforked tongues. They are native to Australia and New Guinea.
