Hematology and biochemistry reference intervals for American alligator (Alligator mississippiensis) in South Florida, USA

We calculated reference intervals for 48 blood parameters from 120 wild American alligators ( Alligator mississippiensis ) in South Florida, US. Although previously reported by others, this study includes additional parameters not yet reported in wild populations. Most previously reported blood parameter values were similar to ours and fell within our reference intervals.

Crocodylus acutus (American crocodile). Diet

Reported prey items of Crocodylus acutus include insects, crustaceans, fish, and large reptiles (Medem 1981. Los Crocodylia de Sur America. Volumen I. Los Crocodylia de Colombia. Colciencias. Bogota, Colombia. 398 pp.; Platt et al. 2002. Herpetol. Rev. 33:202–203; Platt et al. 2013. J. Herpetol. 47:1–10; Balaguera-Reina et al. 2018. Ecosphere 9:e02393). Recently, new potential prey items such as Ligia spp. (isopod), Python molurus bivittatus (Burmese Python), and Arius felis (Hardhead catfish) have also been documented in Florida, USA (Farris et al. 2015. Herpetol. Rev. 46:85–86; Godfrey et al. 2021. Herpetol. Rev. 52:641–642; Godfrey et al. 2022. Herpetol. Rev. 53:315–316). However, to our knowledge the toxic Sphoeroides spengleri (Bandtail Pufferfish) has not been reported in the diet of C. acutus; herein we report on the possibly lethal effects of a C. acutus from consumption of a pufferfish in south Florida.
