 Because it is somewhat difficult to distinguish its head from its 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 the body "helps safeguard pregnancy" while wearing a dead snake "helps rheumatism".They can be found burrowing in the ground under logs, rocks, old tree stumps, and under termite and ant nests.
