Neurological deficits in stranded California sea lions

Veterinary Record, 2019
California sea lions ( Zalophus californianus ) represent a population of marine mammals that has continued to grow since the enactment of the US Marine Mammal Protection Act in 1972. The US population is now estimated to consist of approximately 250,000 individuals,1 which is around carrying capacity.

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.

Toxoplasmosis in a California Sea Lion (Zalophus californianus)

American Journal of Veterinary Research, 1977
SUMMARY Disseminated toxoplasmosis was diagnosed in a female California sea lion that had been used in thermoregulation studies for about 4 years while housed in a small enclosure with a fresh-water pool at the University of Hawaii, Honolulu. Toxoplasma gondii was demonstrated in and around necrotic lesions of the heart and the stomach.

Behavioral thermoregulation in the California Sea Lion

Behavioral Biology, 1974
Behavioral thermoregulation in the California sea lion, Zalophus californianus, was studied during the summers of 1970 and 1971 on San Nicolas and San Miguel Islands, California. Zalophus has a series of behavioral responses which correlates with the rate of radiant input.

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.

Lateralised swimming behaviour in the California sea lion

Behavioural Processes, 2006
Lateralised motor behaviour in the pinnipeds has been subject to little investigation. This study examined the swimming behaviour of seven zoo-housed California sea lions to determine whether they exhibited a directional bias in their motor behaviour.

Acute Viral Hepatitis in California Sea Lions

Journal of the American Veterinary Medical Association, 1979
SUMMARY Acute viral hepatitis was diagnosed in five California sea lions (Zalophus californianus) stranded along the Los Angeles coast. Light microscopy revealed large nuclear inclusion bodies in hepatocytes. Electron microscopy provided evidence that these inclusion bodies were composed of adenovirus-like virions.

Viral Hepatitis (Adenovirus) in a California Sea Lion

Journal of the American Veterinary Medical Association, 1981
SUMMARY A juvenile California sea lion (Zalophus californianus) died 28 days after admission to the California Marine Mammal Center. Necropsy revealed hemorrhagic fluid in the stomach and hepatomegaly. Histologically, there was evidence of multifocal necrotizing hepatitis and acute suppurative bronchopneumonia.

Leptospirosis Epizootic among California Sea Lions

Science, 1971
A Leptospira species is suspected of being the etiological agent in a recent epizootic among California sea lions. The disease was confined to subadult males of the species Zalophus c. californianus .
