About this species
The American crocodile (Crocodylus acutus) is a species of crocodilian found in the Neotropics. It is the most widespread of the four extant species of crocodiles from the Americas, with populations present from South Florida, the Caribbean islands of Cuba, Jamaica, and Hispaniola, and the coasts of Mexico to as far south as Peru, Ecuador, Colombia, and Venezuela.
The habitat of the American crocodile consists largely of coastal areas. It is also found in river systems, but tends to prefer salinity, resulting in the species congregating in brackish lakes, mangrove swamps, lagoons, cays, and small islands. Other crocodiles also have tolerance to saltwater due to salt glands underneath the tongue, but the American crocodile is the only species other than the saltwater crocodile to commonly live and thrive in saltwater. They can be found on beaches and small island formations without any freshwater source, such as many cays and islets across the Caribbean. They are also found in hypersaline lakes; one of the largest known populations inhabits Lago Enriquillo in the Dominican Republic.

El cocodrilo americano, también conocido como lagarto real, lagarto amarillo o cocodrilo de río, asimismo como cocodrilo narigudo, cocodrilo aguja, cocodrilo de la costa (Ecuador), caimán de la costa (Venezuela), caimán aguja (Colombia) o cocodrilo de Tumbes (Perú) (Crocodylus acutus), pertenece a la familia de Crocodylidae. Se le suele confundir con aligátores (Alligator) con los cuales está poco emparentado, estos últimos son más próximos a los caimanes, como el yacaré overo (Caiman latirostris). La diferencia física entre ambos grupos es importante, lo que permite identificarlos sin problema.
