Elasmobranch fish (sharks, skates and rays) are found in a variety of habitats, ranging from full seawater to full freshwater. The osmotic challenges imposed on the animals in these different environments are distinct. ... However, elasmobranch fish do not have the capacity to produce a concentrated urine. Therefore,

Computer-aided techniques were used to reconstruct the complex renal tubular system in the dorsal kidney region of a marine elasmobranch fish, the little skate (Raja erinacea), from a series of light micrographs of serial sections.

An increase in drinking rate of two species of marine elasmobranch fish, Scyliorhinus canicula and Triakis scyllia, acclimated to 80 % sea water was observed following the introduction of 100 % sea water to experimental tanks.

The results demonstrate that the perfused kidney preparation was a viable tool for the investigation of renal parameters in elasmobranch fish and that AVT induced a glomerular antidiuresis.

This has considerable bearing on the view that the bile acids arise from the degradation of cholesterol, and it has been suggested2 that the shark, which belongs to a primitive order of fish, lacks the ability to effect more extensive oxidation of cholesterol to the bile acids.
