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 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; scientific names are usually italicized, with the genus in upper case, species in lower case. Pronunciation of the binomial scientific names need not be difficult: Go here for a simple Latin tutorial.

 

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.
