Alligator mississippiensis (American Alligator): Novel non-native prey

September 29, 2017

American Alligators are opportunistic predators and their food habits have been well studied (Elsey et al. 1992. Proc. Annu. Conf. Southeast. Assoc. Fish Wildl. Agencies 46:57–66, and references therein and below). Composition of
A. mississippiensis diet often varies due to regional limitation in prey availability (Neill 1971. The Last of the Ruling Reptiles. Alligators, Crocodiles, and their Kin. Columbia University Press, New York. 486 pp.; Gabrey 2010. Herpetol. Conserv. Biol. 5:241–250). Additionally, differential digestion rates can lead to over-representation of materials resistant to digestion or under-representation of rapidly digested soft-bodied prey items (Jackson et al. 1974. J. Herpetol. 8:378–381; Garnett 1985. J. Herpetol. 19:303–304; Delany and Abercrombie 1986. J. Wildl. Manage. 50:348–353; Platt et al. 1990. Northeast. Gulf Sci. 11:123–130). We herein report on a novel prey item for A. mississippiensis, which to our knowledge has not previously been reported.
