Bipes (lizard)

Bipes is a genus of amphisbaenians found only in Mexico, the sole living member of the family Bipedidae.[2] Commonly known as ajolotes, they are carnivorous, burrowing reptiles, but unlike other species of amphisbaenians, they possess two stubby forelimbs placed far forward on the body.[3] The shovel-like limbs are used to scrape away soil while burrowing, in a manner similar to a mole.[4] Evidence for their occurrence in the United States is reviewed by Somma (1993).
