Tolerance of Sea Water by the American Crocodile, Crocodylus acutus

Journal of Herpetology, 1981
general. In sea water starved C. acutus lose weight as an inverse function of total body volume. Therefore large crocodiles are capable of prolonged substenance in marine environments, particularly if free water is gained from vertebrate prey in the diet.

Adaptations of Crocodylus acutus and Alligator for life in saline water

Comparative Biochemistry and Physiology Part A: Physiology, 1984
Abstract 1. 1. American crocodiles (C. acutus) weighing less than 200 g are unable to grow when kept in 35 ppt sea water in the laboratory. Yet paradoxically there are some highly saline areas in south Florida where rapid growth occurs. It is possible that these conflicting observations can be reconciled by behavioral osmoregulation of young ...

Identification and characterization of serum complement activity in the American crocodile (Crocodylus acutus)

Veterinary Immunology and Immunopathology, 2010
Incubation of unsensitized sheep red blood cells with serum from the American crocodile (Crocodylus acutus) resulted in a concentration-dependent hemolysis. The hemolytic activity was heat-sensitive, and inhibited by EDTA in a concentration-dependent manner. The EDTA-inhibited SRBC hemolysis could be restored by the addition of excess Ca2+ or Mg2+, but

Hybridization between Crocodylus acutus and Crocodylus moreletii in the Yucatan Peninsula: II. evidence from microsatellites

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2008
AbstractDetecting and quantifying hybridization between endangered or threatened taxa can provide valuable information with regards to conservation and management strategies. Hybridization between members of the genus Crocodylus has been known to occur in captivity and in some wild populations.

Respiration and Metabolism in a Young Crocodile (Crocodylus acutus Cuvier)

Copeia, 1931
M ANY cold-blooded animals have a capacity greatly exceeding that of man for suspension of respiration. The record for man appears to be held by a student of Schneider (1930), who took three deep breaths of oxygen, following a period of forced breathing, and then held his breath for 15 minutes and 13 seconds.

Ecology of a Population of Crocodylus acutus at a Power Plant Site in Florida

Journal of Herpetology, 1985
This paper presents the status and ecology of a population of Crocodylus acutus associated with the Turkey Point power plant in Florida. Distribution, habitat preference, repro- duction, population size and structure, and recruitment and dispersal are discussed. Nesting occurs on spoil berms in the cooling canal system. The Turkey Point population con-

Evolutionary history of Cuban crocodiles Crocodylus rhombifer and Crocodylus acutus inferred from multilocus markers

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2011
AbstractAmong crocodilians, Crocodylus rhombifer is one of the world's most endangered species with the smallest natural distribution. In Cuba, this endemic species coexists with the American crocodile (Crocodylus acutus). Hybridization between these two species is well known in captivity and might occur in the wild, but has never been demonstrated ...

Epibiont sea anemones inhabiting the American crocodile Crocodylus acutus

Marine Biodiversity, 2015
Ticks, leeches, and barnacles are among the various kindsof organisms recorded as epibionts on crocodiles(Huchzermeyer2003; Cupul-Magana et al.2011).Although sea anemones have been reported to live onliving organisms such as sponges, hermit crabs, and seaturtles (Caine 1986; Patzner 2004; Gonzalez-Munoz et al.2012), no previous reports are known of sea

Status and Conservation of Crocodylus acutus at a Naval Base in Aragua State, Venezuela

Journal of Herpetology, 2020
We present the conservation status and ecological characteristics (distribution, habitat preference, reproduction, population size, and structure) of an American Crocodile (Crocodylus acutus) population associated with the naval base “TN Tomas Vega” in Turiamo Bay, Aragua state, Venezuela.

Morphological diversity of the American crocodile (Crocodylus acutus) in the Yucatán Peninsula

Zoomorphology, 2017
Recent evidence suggests that morphological divergence of the American crocodile (Crocodylus acutus) occurred in Greater Antilles under conditions of prolonged isolation and hybridization with the Cuban crocodile (C. rhombifer). We investigated morphological diversity in C.
