This strange little lizard-like reptile has only two, clawed legs, very far forward on its worm-like body. It burrows in porous soils and is endemic to Baja. Rather than being a true lizard, it belongs to the small suborder Amphisbaenia, which is closely related to lizards and snakes. (this is an issue of disagreement within herpetology. some still consider this a group of lizards.)
