Caribbean Sea
Marine biota in the region have representatives of both the Indian and Pacific oceans which were caught in the Caribbean before the emergence of the Isthmus of Panama four million years ago. In the Caribbean Sea there are around 1,000 documented species of fish, including sharks (bull shark, tiger shark, silky shark and Caribbean reef shark), flying fish, giant oceanic manta ray, angel fish, spotfin butterflyfish, parrotfish, Atlantic Goliath grouper, tarpon and moray eels. Throughout the Caribbean there is industrial catching of lobster and sardines (off the coast of Yucatán Peninsula).
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 ("Dragon's Mouths"), 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.), 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.
