American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1992
Splenic volume was measured by computerized axial tomography in three harbor seals (Phoca vitulina) and two California sea lions (Zalophus californianus). Volumes ranged from 228 to 679 ml, representing 0.8-3.0% of calculated percentage body mass. Despite possible variation in the state of splenic contraction during the examination, these values are ...

Biological Reviews, 1993
This review presents summary figures of, and fits growth curves to, data on body lengths (as standard length, SL, whenever possible) of pinnipeds at ages estimated to O.I y. (1) Generalized von Bertalanffy (vB) growth curves are fitted to most data: Lx = L infinity (I - ea(x-x0)b, Lx is length at age x, x0 is the origin of the curve (here chosen a ...

Electrocardiogram of Pinnipeds
American Journal of Veterinary Research, 1972SUMMARY Electrocardiograms were obtained from 6 pinnipeds, including 2 elephant seals (Mirounga angustirostris), 1 harbor seal (Phoca vitulina), and 3 California sea lions (Zalophus californianus). All had marked sinus arrhythmia with cardioacceleration during inspiration and slowing during expiration and respiratory pauses.

Organochlorine Contamination in Pinnipeds
1994Organochlorines, such as PCBs and DDT, are ubiquitous contaminants. Most studies reporting concentrations of organochlorines in pinnipeds have investigated ringed, grey, and harbour seals. Very few studies have been carried out on pinnipeds from the southern hemisphere.

Vanadium Accumulation in Pinnipeds
Archives of Environmental Contamination and Toxicology, 1999Vanadium in four species of pinnipeds (northern fur seals [Callorhinus ursinus], Steller sea lions [Eumetopias jubatus], harbor seals [Phoca vitulina], and ribbon seals [Phoca fasciata]) caught in the Northern Pacific was analyzed using ICP-MS to understand its accumulation and distribution.

Candidiasis in captive pinnipeds
Journal of the American Veterinary Medical Association, 1984Summary Diagnosis, treatment, and possible pathogenesis of candidiasis were studied in 5 species of pinnipeds in captivity: gray seal (Halichoerus grypus), harbor seal (Phoca vitulina), northern fur seal (Callorhinus ursinus), California sea lion (Zalophus califor-nianus), and northern elephant seal (Mirounga an-gustirostris).

Why pinnipeds don’t echolocate
The Journal of the Acoustical Society of America, 2000Odontocete cetaceans have evolved a highly advanced system of active biosonar. It has been hypothesized that other groups of marine animals, such as the pinnipeds, possess analogous sound production, reception, and processing mechanisms that allow for underwater orientation using active echolocation.
