The northern fur seal has a pointed face, long hind flippers and dense insulating underfur. Adult males are much larger and darker than females and develop thick necks and shoulders. The species ranges through the North Pacific and breeds in dense colonies on rocky islands. (Wikipedia, general species account)
Away from breeding sites it spends months at sea, feeding on fish and squid. Males defend territories containing groups of females, while each female normally bears one pup. Gestation includes delayed implantation and lasts approximately a year from mating to birth. (Wikipedia, general species account)
