Market squid (Loligo opalescens) in the diet of California sea lions (Zalophus californianus
) in southern California (1981-1995).
Although Shane (1994) felt that the shooting was mainly directed at California sea lions (Zalophus californianus
), it must be assumed that this shooting caused some additional level of mortality for pilot whales, and because the interactions typically occurred at night, they may have easily gone un-noticed.
It has been shown to provide a therapeutic level for target bacteria starting within hours and lasting for at least 6 days in cattle, 8 days in swine, 10 days in horses after two doses, (3) 5 days in California sea lions (Zalophus californianus
), (14) 7 to 10 days in Asian elephants (Elephas maxim us), (15) 12 days in bearded dragons (Pogona vitticeps), (16) 5 days in ball pythons (Python regius), (17) and 7 days in the male rhesus macaque (Macaca mulatta).
A California sea lion (Zalophus californianus
) is capable of forming equivalence relations.
Social parasitism is defined as an association of 2 or more species where at least 1 species is believed to benefit from another species' food-finding abilities, and has been suggested as an odontocete foraging practice among Bottlenose Dolphins (Tursiops truncatus), California Sea Lions (Zalophus californianus
), common dolphins (Dephinus spp.), and Pantropical Spotted Dolphins (Stenella attenuatei) (Norris and Dohl 1980; Shane 1994; Clua and Grosvalet 2001; Bearzi 2006; Cords and Wursig 2014).
Demersal fish species in Puget Sound are consumed by elasmobranchs, such as Spiny Dogfish (Squalus acanthias) and Bluntnose Sixgill Shark (Hexanchus griseus), and marine mammals, such as the harbor seal (Phoca vitulina; Bromaghin et al., 2013; Howard et al., 2013) and California sea lion (Zalophus californianus
), but we are unaware of any abrupt changes in predator densities in Port Madison to explain these patterns.

On an earlier review of this anomaly in otariids, Acevedo and Aguayo (2008) reported cases in five otariid species: Antarctic fur seal, Arctocephalus gazella (Peter, 1875), Northern fur seal, Callorhinus ursinus Linnaeus, 1758, Steller sea lion, Eumetopias jubatus (Schreber, 1776), Californian sea lion, Zalophus californianus
(Lesson, 1828), and South American sea lion, Otaria flavescens (Shaw, 1800).
Polyomavirus infection in a free-ranging California sea lion (Zalophus californianus
) with intestinal T-cell lymphoma.
Cliff figs were on walls and bottoms of canyons growing on rocks, and they were most common in northern areas of the island, with rather large individuals in the canyon at Punta Los Nacapules (Felger et al., 2011) and above the rookery of California sea lions (Zalophus californianus
) near El Farito.
