Bipes biporus 3 by Jesus Gordolomi
The Mexican mole lizard (Bipes biporus), also known as the Five-toed worm lizard, Ajolote, or Bipes, is a type of elongate burrowing reptile that is often pink and wormlike in appearance.
Bipes biporus is a species of reptile amphisbaenian, which is endemic to the peninsula of Baja California, Mexico.
Bipes is the only amphisbaenian genus with limbs; in particular, members of this genus have small but well developed forelimbs.This genus is also the only squamate taxon in which the forelimbs are better developed than the hind limbs.
As a species, B. biporus always has five digits on each limb, its head is blunt, and it burrows in sandy desert soils on the peninsula of Baja, California. Its tail is short and autotomic, although once it is lost it will not regenerate. This species exhibits no external sexual dimorphism. Like other amphisbaenians, its skin is marked with ringlike annuli, contributing to its wormlike appearance.
