Crocodilian Species

There are 24 species of crocodilian currently recognised (West African Crocodile C. suchus being the most recent addition: Hekkala et al. 2011; Shirley et al. 2013). However, evidence suggests that two species from West Africa warrant being split into 5 species: Osteolaemus tetraspis to O. tetraspis, O. osborni and O. sp. nov.); and, Mecistops cataphractus to Mecistops sp. (Central Africa) and Mecistops sp. (West Africa); Eaton 2010; Shirley et al. 2013]. Although Crocodylus cataphractus is now generally acknowledged as Mecistops cataphractus, the latter name is not formally accepted by the IUCN and CITES.

Descriptions for the 24 species are provided as pdf documents below.
