Mental Rotation in A California Sea Lion (Zalophus Californianus)

Journal of Experimental Biology, 1997
ABSTRACT Mental rotation is a widely accepted concept that suggests an analogue mode of visual information-processing in certain visuospatial tasks. Typically, these tasks demand the discrimination between the image and mirror-image of rotated figures, for which human subjects need an increasing reaction time depending on the angular ...

METASTATIC ADENOCARCINOMA IN TWO CALIFORNIA SEA LIONS, Zalophus c. californianus

Journal of Wildlife Diseases, 1980
Two California sea lions (Zalophus californianus californianus) came to necropsy with morphologically identical metastatic tumors. These were glandular epithelial origin and were widespread throughout the visceral organs. Both animals were found beached and dead within two months and were only 220 km apart.

SUCCESSFULLY TREATED DERMATOMYCOSIS IN CALIFORNIA SEA LIONS(ZALOPHUS CALIFORNIANUS)

Journal of Zoo and Wildlife Medicine, 2013
We describe clinical cases caused by Microsporum gypseum in two subadult male California sea lions (Zalophus californianus). Dermatomycosis is uncommonly reported in pinnipeds, including this species. In these cases, skin lesions were multifocal to coalescing, involved all flippers, and were most pronounced on the ventral surfaces of flippers.

Lead in the California sea lion (Zalophus californianus)

Environmental Pollution (1970), 1973
Abstract Atomic absorption spectrophotometric analysis was conducted on tissue samples taken from nineteen organs in the California sea lion, Zalophus californianus , to determine the distribution and concentration of the heavy metal lead. Lead was found to be accumulated in significantly higher concentrations in hard tissue, bone and teeth, than in

LINGUAL SQUAMOUS CELL CARCINOMA IN A CALIFORNIA SEA LION (ZALOPHUS CALIFORNIANUS)

Journal of Zoo and Wildlife Medicine, 2002
A 28-yr-old female California sea lion (Zalophus californianus) in a commercial aquarium developed an ulcerated lingual tumor and died. Necropsy revealed a moderately differentiated squamous cell carcinoma. Immunohistochemical staining and electron microscopic studies revealed that the tumor cells were strongly positive with anti-keratin-cytokeratin ...

Cardiac Output in Swimming California Sea Lions, Zalophus californianus

Physiological Zoology, 1991
Cardiac output was determined by the thermodilution technique in three California sea lions while resting and while swimming. Metabolic rates increased sevento ninefold above resting rates during maximal exercise. While the sea lions were at rest, stroke volume was also determined by simultaneously counting heart rate during cardiac output ...

Transplacental transfer of organochlorines in california sea lions (Zalophus californianus)

Environmental Toxicology and Chemistry, 2007
Abstract The transplacental transfer of organochlorines (OCs) in California sea lions (Zalophus californianus) was investigated by analyzing blubber samples from 20 female sea lions and their fetuses during the last trimester of pregnancy.

Heavy Metal and Chlorinated Hydrocarbon Residues in California Sea Lions (Zalophus californianus californianus)

Journal of the Fisheries Research Board of Canada, 1975
Samples of various tissues and organs from healthy California sea lions (Zalophus californianus californianus) and sick animals (apparently with leptospirosis) collected along the central Oregon coast in 1970, 1971, and 1973 were analyzed for total mercury, methylmercury, cadmium, and chlorinated hydrocarbons.

Temporal patterning in sea lion barking (Zalophus californianus)

Behavioral Biology, 1977
Quantitative data were obtained to determine whether the temporal patterning of barks by male California sea lions ( Zalophus californianus ) could be used in their acoustical communication. The most important findings were: (a) The mean number of barks per series was significantly greater while a bull was locomoting than while he was stationary.
