1. Conservation status according to the IUCN Red List of the International Union for the Conservation of Nature (IUCN) (aka World Conservation Union). Note that an isolated population of a species may have a different status than that of the species as a whole, the latter being designated above.

 

2. The current singly-classified species will be separated into at least two distinct species, based on genetic analysis. The species name suchus was reinstated from Étienne Geoffroy Saint-Hilaire's identification of the crocodile in 1807, which was abandoned when scientists determined that it was a synonym for niloticus.

 

3. Conservation status for this species is not yet established; one may accept the genus' status in its place for the time being.

 

4. Reclassified in 2010 from genus Crocodylus, Mecistops is now considered to be two distinct species, based on genetic analysis; the second has not been named. "Mecistops" is not yet recoginized by IUCN.

 

5. In December 2008 it was revealed that the genus Osteolaemus was determined by genetic analysis to consist of three species. The formerly accepted subspecies, osbornii, may be accepted as a second species, while the third is yet unnamed.

 

6. There is controversy over this classification, as fossil and morphological evidence identifies it with Family Crocodylidae, while biochemical and immunological evidence suggests Family Gavialidae as appropriate.

 

7. There has been speculation among experts that there may be more than one species within this genus.
