... projection areas are somatotopically arranged. Sharks and rays can possess thousands of ampullae. Amongst other functions, the use of electroreception during prey localization is well documented. The distribution of ampullary pores in the skin of elasmobranchs is influenced by both the phylogeny and ecology...

... that there might be considerable interspecific variation in the importance of the olfactory sense. Wobbegong sharks, with their sedentary lifestyle and ambush predatory technique, probably utilize their senses differently than other shark species, making it difficult to generalize about their olfactory...

...Thomas J. Lisney; Shaun P. Collin The total number, distribution and peak density of presumed retinal ganglion cells was assessed in 10 species of elasmobranch (nine species of shark and one species of batoid) using counts of Nissl-stained cells in retinal wholemounts. The species sampled include...

... of the peripheral nervous system (PNS) myelin of mammals. The exact role that Po protein has played in the evolution of myelin is still unclear, but several phylogenetic observations suggest that it is a crucial component in the development of myelin as a multi-lamellar membrane structure. Sharks, which appeared...

...Dolores M. Schroeder; S.O.E. Ebbesson The nonolfactory afferents to the telencephalon of the nurse shark were determined by tracking ascending degenerating fibers with silver impregnation techniques. Of the three ascending fiber bundles, the largest tract is entirely crossed and terminates...

...Thomas J. Lisney; Shaun P. Collin Variation in relative eye size was investigated in a sample of 46 species of elasmobranch, 32 species of sharks and 14 species of batoids (skates and rays). To get a measure of eye size relative to body size, eye axial diameter was scaled with body mass using least...
