General Information

Amphisbaenids are legless, worm-like lizards with elongated bodies nearly uniform in diameter. They are covered with ring-like scales similar in appearance to earthworms. They are underground animals, hence the eyes have degenerated to tiny indistinct spots under the rings.


The Common Blind Snake Lizard is pinkish-brown on the head and tail with many dark spots on the annuli (body rings) of which there are between 214 and 237 in this species. It measures 10 inches (260 millimeters) in length, from snout to vent. Because it is somewhat difficult to distinguish it's head from it's tail it is sometimes referred to as a "two-headed snake" (in Puerto Rico "Culebra de dos cabezas") by local people. According to folklore, wearing a live Amphisbaena on your body "helps safeguard pregnancy" while wearing a dead snake "helps rherumatism".


They can be found burrowing in the ground under logs, rocks, old tree stumps and under termite and ant nests.


They live in dense woodlands, thickets and caves in Puerto Rico, Isla Vieques, Isla Culebra and the Virgin Islands.
