Chilabothrus chrysogaster, commonly known as the Turks Island boa or the Southern Bahamas boa, is a species of snake found in the Southern Bahamas (Inagua, Crooked Island and Acklins) and the Turks and Caicos Islands. Local names include rainbow boa (not to be confused with Epicrates cenchria, the "real" rainbow boa), Bahamas cat boa, rainbow snake, and fowl snake. Like all boids, it is not a venomous species.
