List of crocodilians

A member of this order is called a crocodilian, or colloquially a crocodile.

The 9 genera and 28 species of Crocodilia are split into 3 subfamilies: Alligatoridae, alligators and caimans; Crocodylidae, true crocodiles; and Gavialidae, the gharial and false gharial.

Ranges are based on the IUCN red list for that species unless otherwise noted.

The order Crocodilia consists of 28 extant species belonging to 9 genera.

Modern molecular studies indicate that the 9 genera can be grouped into 3 families.

Family Alligatoridae (Alligators and caimans) Family Crocodylidae (True crocodiles) Family Gavialidae (Gharial and false gharial) The extant Alligatoridae can be recognised by the broad snout, in which the fourth tooth of the lower jaw cannot be seen when the mouth is closed.

Unknown [9] The extant Crocodylidae have a variety of snout shapes, but can be recognised because the fourth tooth of the lower jaw is visible when the mouth is closed.

Unknown [22] Gavialidae can be recognised by the long narrow snout, with an enlarged boss at the tip.
