Crocodylus acutus
The American crocodile is the most widespread of the four extant species of crocodiles from the Americas. It inhabits waters such as mangrove swamps, river mouths, fresh waters, and salt lakes, and can even be found at sea, hence its wide distribution throughout southern Florida, the Greater Antilles (excluding Puerto Rico and Isla de la Juventud, where it is replaced by the introduced spectacled caiman), Martinique, southern Mexico (including the Yucatán Peninsula), Central America, and the South American countries of Colombia, Peru, Venezuela, and Ecuador. The American crocodile is especially plentiful in Costa Rica.
