At the Crocodilian Heart of the Matter
Science, 2000The interpretation of the haemodynamics of the crocodilian heart by Fisher et al. in their report “Cardiovascular evidence for an intermediate or higher metabolic rate in an ornithischian dinosaur” (21 Apr., p. [503][1]) is flawed and hence casts doubt on their conclusion that dinosaurs had “

Anatomy of the crocodilian spinal vein
Journal of Morphology, 2003AbstractThe crocodilian spinal vein is remarkably robust yet historically overlooked. Using corrosion casting, we describe the anatomy of this vessel and its connections with the caval and hepatic venous systems in representatives from four crocodilian genera.

Electrocardiogram of the Crocodilian Heart
Nature, 1951As part of an investigation of the histology and functional anatomy of the crocodilian heart, electrocardiograms of the heart in intact animals (Nile crocodiles) were recorded. Part of a tracing, using the standard lead, throat to abdomen, is shown in Fig. 1.

Veterinary Clinics of North America: Exotic Animal Practice, 2001
With declining crocodilian populations worldwide, a greater interest in the conservation of these animals in the wild and in captivity is ongoing. This effort has created a demand for safe and effective ways to handle and immobilize crocodiles for transport and relocation.

This chapter focuses on crocodilians, including alligators and caimans. The Spectacled Caiman is a medium-sized alligatorid species. Although very wary by nature, it can nonetheless be a dangerous animal under the wrong circumstances. Populations of the Spectacled Caiman in the United States were derived from the pet trade.

Questions in Crocodilian Physiology
Zoologica Africana, 1975Morphologists, physiologists, behaviourists and ecologists have traditionally asked different and often mutually exclusive questions within their different conceptual frameworks. Only the concept of natural selection and the idea that the animals have been modified for one or another mode of life history provide a common denominator or common framework

OSMOREGULATION IN CROCODILIANS
Biological Reviews, 1988Summary1. The osmoregulatory strategies of crocodilians in both saline and fresh‐water environments are discussed and dissected into their separate components.2. Contrasts between members of the Alligatoridae and the Crocodylinae emerge repeatedly in aspects such as integumental permeabilities, functioning of the renal/cloacal system, and the presence ...

Are Seeds Consumed by Crocodilians Viable? A Test of the Crocodilian Saurochory Hypothesis
Southeastern Naturalist, 2014Abstract Many animal species are important dispersers of seeds; however, relatively little attention has been paid to the seed-dispersal capabilities of reptiles, and almost nothing is known about the seed-dispersal capabilities of crocodilians. This lack of information is surprising given that seeds have been found in the stomach contents of a ...

Respiratory patterns in crocodilian reptiles
Respiration Physiology, 1970Abstract This paper describes the typical respiratory pattern of caimans and alligators and shows the great range of respiratory activity even in quiet, isolated caimans, with average ventilatory periods varying from 6–22 sec in length and consisting of an average of from 1–5 breaths, and nonventilatory periods averaging from 13 sec-3 min in length ...
