Fur seals are often found near isolated islands or peninsulas, and can be seen hauling out onto the mainland during winter. Beginning in the 1790s, the ports of Stonington and New Haven, Connecticut, were leaders of the American fur seal trade, which primarily entailed clubbing fur seals to death on uninhabited South Pacific islands, skinning them, and selling the hides in China. Until recently, fur seals were all grouped under a single subfamily of Pinnipedia, called the Arctocephalinae, to contrast them with Otariinae – the sea lions – based on the most prominent common feature, namely the coat of dense underfur intermixed with guard hairs. © 1996-2015 National Geographic Society, © 2015- All fully furred species molt; phocids molt once a year, while otariids gradually molt all year. Nonetheless, environmental degradation, competition with fisheries, and climate change potentially pose threats to some populations. The fore flippers of the fur seal are dark brown to black. The northern fur seals begin their breeding season as early as June due to their region, climate, and resources. Eared seals use all 4 limbs for walking on land and ice.
