The sea otter population is thought to have once been 150,000 to 300,000, [24] stretching in an arc across the North Pacific from northern Japan to the central Baja California Peninsula in Mexico. The fur trade that began in the 1740s reduced the sea otter's numbers to an estimated 1,000 to 2,000 members in 13 colonies.
The sea otter was once abundant in a wide arc across the North Pacific ocean, from northern Japan to Alaska to Mexico. By 1911, hunting for the animal's luxurious fur had reduced the sea otter population to fewer than 2000 individuals in the most remote and inaccessible parts of its range. The IUCN lists the sea otter as an endangered species.
Population sizes are largely unknown, though two species, the sea mink and Japanese otter, were hunted to extinction in 1894 and 1979, respectively, and several other species are endangered. Some species have been domesticated, e.g. the ferret and some populations of the South American tayra .
The majority of the world’s sea otters (90%) are northern sea otters living off of the coast of Alaska. Many of these otters can be found in the waters around Glacier Bay National Park, Kodiak ...
The first male sea otter arrived in the Elkhorn Slough, 35 miles north of Bixby Cove, in the late 1990s. Only in the early 2000s did females arrive, and soon thereafter pups, said Wasson.
They were nearly hunted to extinction back in the 1700s and 1800s, and while the population has recovered, the number one threat to sea otters today are oil spills caused by humans.
The North West Coast during the maritime fur trade era, about 1790 to 1840. The maritime fur trade, a ship-based fur trade system, focused largely on acquiring furs of sea otters and other animals from the indigenous peoples of the Pacific Northwest Coast and natives of Alaska.
