List of snakes of Trinidad and Tobago

Forty-seven species of snake have been recorded in Trinidad and Tobago, making the snake population of this area the most diverse in the Caribbean. Forty-four of these snake species are found in Trinidad and twenty-one in Tobago. Many of these species are South American, most of which are present in Venezuela. 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 been recorded on only one of them, Caledonia Island. Snakes have been recorded on one island off Tobago, Little Tobago. Four species are venomous: two coral snake species (Micrurus spp.[note 1]), the fer-de-lance (Bothrops atrox) and the South American bushmaster (Lachesis muta). The common coral (Micrurus fulvius) is found on at least two of the Bocas Islands: Gaspar Grande and Monos. No venomous snakes inhabit Tobago.
