Abstract :
Reliable and highly replicable electro- retinograms (ERGs) have been obtained from California sea lions (Zalophus californianus) with non-invasive techniques. Preliminary results indicate that the ERG of sea lions is most responsive to stimulation with wavelengths from the blue, green, and orange portions of the human´s visible spectrum. Stimulation with red light appears to produce small, but measurable, ERGs in the sea lion. Electrophysiological study of the visual and other sensory processes of marine mammals holds great potential for basic research, for training assessment, for clinical application, and for developing an understanding of the sensory processes of sea dwelling creatures.
