The Mexican Mole Lizard, or Bipes biporus, is an odd looking creature. It looks like a long earthworm with two front legs with claws that act like paddles. It burrows in porous soils, just like an earthworms. It’s not a true lizard but it’s closely related to lizards and snakes and belongs to the small suborder Amphisbaenia which is endemic to Baja California, Mexico
The Mexican Mole Lizard is also commonly known as the five-toed worm lizard. It is one of four species of amphisbaenians that have legs. It should not be confused with a salamander.
About the Mexican Mole Lizard
Mexican Mole Lizards are pink, lizard-like reptiles, 18–24 cm (7.1–9.4 in) snout-to-vent length and 6–7 mm (0.24–0.28 in) in width. They live for one to two years. Their skin is closely segmented to give a corrugated appearance, and like earthworms, their underground movement is by peristalsis of the segments.
The forelegs are strong and paddle-like, while the hindlegs have disappeared, leaving behind only vestigial bones visible in X-rays. The feet fold back for a “swimming” motion, yet come into play for guidance and digging.
