Type locality: "les bords du Mississipi," U.S.A.  
TypesHolotype: MNHN, according to Guibé (personal reply in Hemming 1956) 
CommentHolbrook (1842) emended Daudin's `mississipiensis' to the present spelling, and that emendation was declared valid by the Intl. Comm. Zool. Nomen., see Hemming 1958, Opin. Declar. Rendered Intl. Comm. Zool. Nomen. 1F(F.8):87-126 (after King & Burke 1989).

Reproduction: One of the many reptile species which have temperature-dependent sex determination (TSD, see Valenzuela & Lance 2004 for details).

Genetics: This is one of 6 reptile species whose genome is currently being sequenced by the Genome10K project.

Type species: Crocodilus lucius CUVIER 1807 is the type species of the genus Alligator CUVIER 1807.
