Crocodiles (family Crocodylidae) or true crocodiles are large, semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.The term “crocodile” is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both ...
The crocodile was one of several animals the Egyptians mummified. [171] West African peoples also associated crocodiles with water deities. During the Benin Empire, crocodiles symbolised the power of the oba (king) and linked him to the life-giving rivers. [172] The Leviathan described in the Book of Job may have been based on a crocodile. [173]

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.

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]
A fossil reveals how a now-extinct species of dugong was swimming in the sea about 15 million years ago when it was preyed upon by a crocodile and a tiger shark.
Crocodylomorpha in the modern sense, as defined by Paul Sereno in 2005, is phylogenetically defined as the most inclusive clade containing Crocodylus niloticus (the Nile crocodile), but not Rauisuchus tiradentes, Poposaurus gracilis, Gracilisuchus stipanicicorum, Prestosuchus chiniquensis, or Aetosaurus ferratus.
