Crocodylidae

American crocodile Crocodylus acutus, photographed by Tomascastelazo.


Belongs within: Neosuchia.

The family Crocodylidae includes the crocodiles Crocodylus and their closest fossil relatives. The false gharial Tomistoma schlegelii may also be a member of this group, though its phylogenetic position has been open to debate. Members of this family have relatively narrow, elongate heads. The largest living species, the saltwater crocodile Crocodylus porosus, may reach lengths of well over six metres. Other species may be considerably smaller; the Australian freshwater crocodile C. johnstoni, for instance, is usually less than two metres in length.
