The Biology of Sharks and Rays

A. Peter Klimley

University of Chicago Press

This chapter discusses the underwater photic environment, the anatomy of the eye, the spectral sensitivities of visual pigments, and the visual capabilities of the different cartilaginous fishes. All of the sharks, rays, and chimaeras have small pores on the underside of their heads connected to gel-filled tubules that lead to the nervous system, called the ampullae of Lorenzini. These sense minute electrical fields, which are produced by fish, clams, and crabs while out of sight buried in the sand.

Keywords:   cartilaginous fishes, vision, eye, underwater photic environment
