Cheloniidae

Order: Testudines · Family: Cheloniidae

Sea turtles (Cheloniidae) are a family of large turtles found in all tropical seas and some subtropical and temperate seas. Sea turtles developed from land turtles about 120 million years ago and are well adapted to life in the sea. They feed mainly on jellyfish, crustaceans and squid. 4 chelonids were recorded in both Trinidad and Tobago.

Dermochelyidae

Order: Testudines · Family: Dermochelyidae

The leatherback sea turtle (Dermochelys coriacea) is the largest of all existing turtles and can reach a length of 2 metres (6.6 ft) and a weight of more than 600 kilograms (1,300 lb). It is found in all tropical or subtropical seas. Unlike most sea turtles, leatherbacks are often found in the colder waters of temperate zones. It is the only extant species of the Dermochelyidae family and is considered critically endangered. All other species in this family are only known as fossils. This species occurs in both Trinidad and Tobago.

Order: Testudines · Family: Emydidae

This family is made up of 10 genera that contain more than 50 species. One of them occurs in Trinidad.

Alligatoridae

Order: Crocodylia · Family: Alligatoridae

The alligatoridae (Alligatoridae) are a family of crocodilian sauropsids (reptiles) native to the Americas, including alligators and caimans. It includes the extant genera Alligator, Caiman, Melanosuchus and Paleosuchus, as well as numerous extinct genera. Of the 7 species that inhabit America, 2 occur in Trinidad.

Crocodylidae

Order: Crocodylia · Family: Crocodylidae

Crocodilians (Crocodylidae) are a family of archosaur sauropsids (reptiles) commonly known as crocodiles. This family includes 14 species of large semi-aquatic reptiles that inhabit tropical areas of the world. Crocodiles tend to congregate in freshwater habitats, such as rivers, lakes, wetlands, and sometimes brackish water. They are ambush hunters who usually wait for their prey, generally fish or land animals, to approach, before attacking them. They feed mainly on vertebrates such as fish, reptiles and mammals, and sometimes invertebrates such as mollusks and crustaceans, depending on the species. As cold-blooded predators, they have a slow metabolism and can therefore survive long periods without food. Despite their slow appearance, crocodiles are very fast over short distances, even out of water. However, these 2 species are considered waifs to the island. Meaning, that Trinidad and Tobago is not in their natural distribution. With these two species likely coming in from the surrounding waterways of Venezuela.
