Pinnipeds, like other mammals, must replace old skin and hair. Most animals shed hairs year-around, but elephant seals do it all at once. The molting process is so abrupt in the elephant seal that it is called acatastrophic molt. During the spring and summer months,elephant sealsreturn to...
The California coast provides a unique study system for investigating the effects of warming and habitat quality on the thermoregulatory capacity of the northern elephant seal (NES). In California, island rookeries such as the offshore site at the Farallon Islands National Wildlife Refuge are ...

The ecology of the northern elephant seal,Mirounga angustirostris, (Fig.1) facilitates acquisition of foraging behavior data using archival tagging instrumentation, making it an ideal study species to address questions on the effects of both natural and anthropogenic disturbance on the foraging success ...
Mummified southern elephant seal remains from the Victoria Land Coast, Antarctica.

Northern elephant sealThermal windowPinnipeds spend extended periods of time on shore during breeding, and some temperate species retreat to the water if exposed to high ambient temperatures. However, female northern elephant seals (Mirounga angustirostris) with pups generally avoid the water, presumably...
