Applied Herpetology, 2003
All species of crocodilians are long-lived, top-level carnivores that are integral components of aquatic, wetland, and marine/estuarine ecosystems. However, they are often excluded from studies on environmental contamination and ecological risk assessments.

Allosteric regulation of crocodilian haemoglobin
Nature, 1981The oxygen affinity of most vertebrate haemoglobins in the absence of diffusible electrolytes is much higher than that of blood. In the red cell this affinity is lowered by organic phosphates, hydrogen ions, chloride ions and CO2 (refs 1–5). Similarly, crocodilian haemoglobin also has a much higher oxygen affinity than crocodile blood, but this is due ...

Flow dynamics of the crocodilian heart
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1989We report for the first time the flow events corresponding to the pressure patterns in the left and right aorta (LAo and RAo) during the cardiac cycle in the caiman (Caiman crocodylus ssp). These experiments show a complex LAo flow pattern; an initial small anterograde flow in the early systole is reversed to a backflow at midsystole.

Crocodilians are a ubiquitous component of the vertebrate fauna of the Wealden Supergroup of southern England. In the past 160 years, 11 species belonging to as many as nine genera have been recognized. Many of these taxa are represented by well-preserved specimens, often comprising complete skulls and articulated or associated postcranial skeletons ...

Diets of Amazonian Crocodilians
Journal of Herpetology, 1987Differences in diets among Amazonian crocodilians can largely be related to habitat selec- tion. Caiman crocodilus, Melanosuchus niger and Paleosuchus palpebrosus, which occur around rivers and lakes have similar diets: small individuals eat invertebrates and large individuals eat invertebrates and fish.

Sinusoidal daily and seasonal patterns of change in body temperature (Tb) measured at 15 degrees S latitude in 30-1,000 kg Crocodylus porosus are explicable by comparatively simple mathematical equations into which are fed only behaviour pattern, environmental data and body mass. This confirms that C.

A Formulary for Lizards, Snakes, and Crocodilians
Veterinary Clinics of North America: Exotic Animal Practice, 2000A formulary of drug dosages for use in lizards, snakes, and crocodilians based primarily on a survey of the existing literature is provided. The formulary is presented as a series of four tables: antimicrobial drugs; parasiticide drugs; anesthetic and analgesic drugs; and miscellaneous drugs. An extensive bibliography is included.

Acoustic behavior in crocodilians.
The Journal of the Acoustical Society of America, 2010Sound production in reptiles is generally limited in scope, yet crocodilians have developed a modest repertoire of vocal and non-vocal acoustic signals to convey a range of different information. This ability is perhaps less surprising considering that their Archosaur heritage is shared with dinosaurs and birds, and basic similarities to avian ...
