Underwater Visual Discrimination by the California Sea Lion

Science, 1965
Two captive sea lions ( Zalophus californianus ) presented with a series of size-discrimination tasks showed preferences for the smaller of two targets and gave virtually errorless performances despite changes in the form and relative size of the targets.

Cambered profile of a California sea lion's body

Journal of Experimental Biology, 2015
More than 100 research articles have referred to an experimental study by [Feldkamp (1987][1]) on the California sea lion, which mentions that its body resembles a symmetric airfoil, NACA 66018. We believe that perhaps an oversimplification has been made in this comparison.

Water Balance in California Sea Lions

Physiological Zoology, 1970
which these animals haul out are truly desert islands, as dry and nearly as hot as the nearby mainland. These sea lions have no access to fresh water. The question naturally arises, do they drink sea water? If they drink sea water, they must somehow get rid of the salts.

SURVEY OF DISEASES IN FREE-LIVING CALIFORNIA SEA LIONS

Journal of Wildlife Diseases, 1974
Fifty-one diseased California sea lions, Zalophus californianus, that stranded on southern California beaches were examined by necropsy.

DISSEMINATED BLASTOMYCOSIS IN TWO CALIFORNIA SEA LIONS (ZALOPHUS CALIFORNIANUS)

Journal of Zoo and Wildlife Medicine, 2000
Two captive California sea lions (Zalophus californianus) from different facilities were diagnosed with disseminated blastomycosis. The first, a 12-yr-old male, died after a 3-wk history of progressive anorexia and lethargy. Gross examination revealed acute jejunitis with focal perforation and associated peritonitis, along with severe purulent ...

Color vision in the California sea lion (Zalophus californianus)

Vision Research, 1992
Three California sea lions were trained to discriminate between a colored stimulus and two shades of gray in a 3-fold simultaneous choice situation. The colors blue, green and red were tested against shades of gray varying from low to high relative brightness. All animals distinguished blue from gray; two animals also distinguished green from gray; but
