There are 24 species of crocodilian currently recognised, with the West African Crocodile C. suchus being the most recent addition (Hekkala et al. 2011; Shirley et al. 2014). However, evidence suggests that two West African species warrant being split into 5 species: Osteolaemus tetraspis to O. tetraspis, O. osborni and O. sp. nov.) (Eaton 2010); and, Mecistops cataphractus to M. leptorhynchus.
