The Mexican mole lizard, (Bipes biporus), also known as the five-toed worm lizard, ajolote, or simply as Bipes, is a species of amphisbaenian, which is endemic to Baja California, Mexico. It is one of four amphisbaenians that have legs, and one of three non-extinct species of animals to have only two limbs, with the Lesser and Greater Siren. It should not be confused with the axolotl, a salamander which is usually called ajolote.
