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 name was changed due to the misspeliing of "Mississippi" in the Latinized species name.

 

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

 

4. The "nominate" subspecies is the primary one which serves as the "name" of the species.

 

5. The word, "Yacaré", or "Jacaré" (with or without the accent) is Portuguese, but by common usage among English-speakers, is their de facto name of choice.
