My Guide to Blindsnakes/Threadsnakes in The Bahamas

Blindsnakes are a group of fossorial worm-like snakes. This guide should help with identification regarding species in the Bahamas. There are four Typhlopidae species and one Leptotyphlopidae species found in the Bahamas. Most are endemic to only certain islands in the Caribbean. The species are listed here:

• Cubatyphlops biminiensis, the Bahaman slender blindsnake.
• Cubatyphlops paradoxus, the Inagua blindsnake.
• Epictia columbi, the San Salvador blindsnake.
• Indotyphlops braminus, the Brahminy blindsnake.
• Typhlops lumbricalis, the Earthworm blindsnake.
