Chilabothrus – West Indian boas

This genus is a fascinating group of non-venomous boas native to the Caribbean, especially found on islands like the Bahamas, Hispaniola, Puerto Rico, Jamaica, and the Virgin Islands. These snakes are commonly referred to as West Indian boas, and they play a crucial ecological role in their environments as top native predators. Members of Chilabothrus are generally secretive, slow-moving, and nocturnal, and they’re often beautifully patterned, with some species displaying stunning iridescent scales that shimmer in the light.

Most Chilabothrus species are medium to large-sized snakes, ranging from around 1 to over 3 meters (3 to 10 feet) in length, depending on the species. They have strong, muscular bodies, triangular heads, and vertical pupils—all common features of boas. Their coloration can vary widely, from earthy browns and blacks to rich reds, golds, and even purples, often with marbled or speckled patterns that help them blend into forest floors, rocky outcrops, or caves. Some, like the Cuban boa (Chilabothrus angulifer), are among the largest snakes in the Caribbean.

These boas are constrictors, meaning they subdue prey by wrapping around it and squeezing, cutting off blood flow and breathing before swallowing it whole. They feed on a variety of animals, including rodents, birds, lizards, bats, and even small amphibians. In fact, a few species are known to hang at cave entrances to snatch bats mid-flight—a rare and remarkable hunting behavior among snakes!
