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, Hispaniola, [4] and the coasts of Mexico to as far south as Peru, Ecuador, Colombia, and Venezuela.
The generic name, Crocodylus, was proposed by Josephus Nicolaus Laurenti in 1768. [2] Crocodylus contains 13–14 extant (living) species and 5 extinct species. There are additional extinct species attributed to the genus Crocodylus that studies have shown no longer belong, although they have not yet been reassigned to new genera.

Cladistically, it is defined as Crocodylus niloticus (the Nile crocodile) and all crocodylians more closely related to C. niloticus than to either Alligator mississippiensis (the American alligator) or Gavialis gangeticus (the gharial). [5] This is a stem-based definition for crocodiles, and is more inclusive than the crown group Crocodylidae. [3]
