The Visual System of Sharks: Adaptations and Capability

摘要: The visual system of elasmobranchs is reviewed with primary emphasis on recent investigations. Starting the ocular adnexa and whole eye working through cornea, uvea, ciliary zone, lens, retina, structure peculiar to sharks described. Visual function as revealed by electrophysiology, photochemistry, behavioral studies also reviewed. discussion ends a description elasmobranch median eye. overall impression that far from having poor vision, these extremely successful marine predators apparently have been provided high degree development. While advances in our understanding shark impressive, much work remains, and, for example, entire areas such resolution spatial vision are unstudied. Probably greatest mystery relation between exquisitely adapted natural behavior sharks. Thus what needed linking hypothesis laboratory observed field.
