Crocodylus is one of three genera from the subfamily Crocodylinae of the family Crocodylidae.

Established species include five extinct species:[1]

The 13 living species are:

Phylogeny[edit]

The cladogram below follows the topology from a 2011 analysis of mitochondrial DNA sequences by Robert W. Meredith, Evon R. Hekkala, George Amato and John Gatesy.[4]

 Crocodylus 
 Asia-Australia 


C. porosus




C. palustris



C. siamensis






C. johnsoni




C. novaeguineae



C. mindorensis





 Africa-New World 

C. suchus




C. niloticus


 New World 

C. rhombifer




C. moreletii




C. acutus



C. intermedius








The cladogram below follows the topology from a 2012 analysis of morphological traits by Christopher A. Brochu and Glenn W. Storrs. Many extinct species of Crocodylus might represent different genera. C. suchus was not included, because its morphological codings were identical to these of C. niloticus. However, the authors suggested that it could be explained by their specimen sampling, and considered the two species to be distinct.[1]
