Bipedidae are very small, usually ranging from 120 to 240 mm. They lack external hind limbs and are the only amphisbaenians with well-developed fossorial front limbs, which each include five claws.[3] They have a short tail that does not regenerate if lost. They use their blunt head for burrowing by ramming it into the soil, and usually prey on arthropods.[4]
