, 2009 This chapter presents a general overview of the anatomy, physiology, and treatment methodology for crocodilians. Most crocodilians grow to be larger than other reptile species and, therefore, have significant space requirements. Like most animals requiring an aquatic environment, crocodilians need water that is clean and free of disease.

Do crocodilians get the flu? Looking for influenza A in captive crocodilians [PDF]
Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2008 AbstractIt is well established that several wild aquatic bird species serve as reservoirs for the influenza A virus. It has also been shown that the influenza A virus can be transmitted to mammalian species such as tigers and domestic cats and dogs through ingestion of infected birds. Another group of animals that should also be considered as potential

Ontogeny of murine bony semicircular canal form
The Anatomical Record, EarlyView.Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Osmoregulation in Crocodilians [PDF]
American Zoologist, 1989 Recent crocodilians live primarily in freshwater habitats. However two species ( Crocodylus acutus and C. porosus ) are estuarine specialists; two others ( C. niloticus and C. johnstoni ) that are primarily found in fresh water, have estuarine populations. Routes of uptake of water and sodium include drinking, feeding and associated incidental drinking,

The Anatomical Record, EarlyView.Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Evaluation of factors associated with predation on Caiman latirostris nests (Crocodylia: Alligatoridae) in Argentina [PDF]
, 2016 La predación es una de las mayores causas de pérdida de huevos de cocodrilianos. Estudios previos reportan que los predadores detectan a las presas mediante signos visuales u olfativos, por ejemplo los producidos por el hombre.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus
The Anatomical Record, EarlyView.The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.
