Sea lions are any of seven species in six genera of modern pinnipeds including one extinct one (the Japanese sea lion). Sea lions are characterized by the presence of external ear pinnae or flaps, long front flippers, and the ability to walk on four flippers on land. Their range extends from the subarctic to tropical waters of the global ocean in both the northern and southern hemispheres with the notable exception of the Atlantic Ocean. They are generally found in shallow waters of coastal areas of both with abundant food resources.[1] Image File history File linksMetadata Download high-resolution version (1275x835, 494 KB) Hundreds of California Sea Lions sunbathing on Pier 39 in San Francisco. ...

Taxonomy

Together with the fur seals, they comprise the Otariidae family, collectively known as eared seals. Until recently, sea lions were grouped under a single subfamily called Otariinae to distinguish them from the fur seals Arcocephalinae, based on the most prominent common feature between all species, namely the lack of dense underfur characteristic of the latter. Recent genetic evidence, however, strongly suggests that the Callorhinus, the genus of the Northern fur seal is more closely related to some sea lion species than to the fur seal genus Arctocephalus.[2] Therefore the fur seal/sealion subfamily distinction has been largely eliminated. Nonetheless, all sea lions have certain features in common, in particular the coarse, short fur, greater bulk and larger prey than fur seals. Genera Callorhinus Arctocephalus Fur seals make up one of the two distinct groups of mammals called seals. Both the fur seals and the true seals are members of the Pinnipedia, which is usually regarded as a suborder of the order Carnivora but sometimes as an independent order. ... Binomial name Callorhinus ursinus Linnaeus, 1758 Range map The Northern Fur Seal, Callorhinus ursinus, is an eared seal. ...


Interactions with humans

Some species of sea lions are readily trainable and are often a popular attraction at zoos and aquariums. The archetypical circus seal performing behaviors such as throwing and catching balls on their noses and clapping is almost always, in fact, a sea lion.


The government of Japan has set a quota of 116 kills per year in Hokkaido,[citation needed] as sea lions are seen as a threat to commercial fisheries. International environmentalists and local fishery advocates continue to debate the issue. A fishery (plural: fisheries) is an organized effort by humans to catch fish or other aquatic species, an activity known as fishing. ...


The Norwegian government has set a quota of 200 kills per year.[citation needed]

The U.S. Navy Marine Mammal Program (NMMP) is a program administered by the U.S. Navy which studies the military use of marine mammals  — principally Bottlenose Dolphins and California Sea Lions  — and trains circus animals to perform tasks such as ship and harbor protection, mine detection and clearance, and...

Sea lion attacks on humans are rare, but have occurred in at least a single notable case, in which a 13 year-old Australian girl was attacked while in the water. Sources said that the likeliest explanation was that the animal was attempting to play with the girl.[4][5][6]
