List of snakes of Trinidad and Tobago

This is a list of snakes which have been recorded in Trinidad and Tobago. Forty-seven species have been recorded - forty-four in Trinidad and twenty-one in Tobago, making the snake population of this area by far the most diverse in the Caribbean. Many of these species are South American, most of which are present in Venezuela.

Cascabel Dormillon or Cook's Tree Boa (Corallus ruschenbergerii), Caroni Swamp, Trinidad.

Trinidad and Tobago consists of two main islands, Trinidad and Tobago, and several smaller islands. The "Bocas Islands", which lie between Trinidad and Venezuela, in the Bocas del Dragón (Dragons' Mouth), consist of Chacachacare, Monos, Huevos and Gaspar Grande. Several smaller islands lie off Trinidad, but snakes have only been recorded on one of them, Caledonia Island. Snakes have only been recorded on one island off Tobago, Little Tobago.

Only four species are venomous - two Coral Snakes (Micrurus spp.), the Fer-de-lance (Bothrops atrox) and the Bushmaster (Lachesis muta). The Common Coral is found on one of the Bocas Islands (Gaspar Grande). No venomous snakes occur in Tobago.
