The Steller sea lion or Eumetopias jubatus, also known as the Steller’s sea lion and northern sea lion, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus Eumetopias and the largest of the eared seals. Among pinnipeds, it is inferior in size only to the walrus and the two species of elephant seals.

The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion or Eumetopias jubatus has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers over an extensive portion of their northern range in Alaska.

Adult Steller sea lion or Eumetopias jubatus are lighter in color than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Steller sea lion pups are born almost black, weighing around 51 lbs., and remain dark in coloration for several months. Females and males both grow rapidly until the fifth year, after which female growth slows considerably.

Adult Steller sea lion or Eumetopias jubatus females measure 7.5–9.5 ft. in length, and weigh 530–770 lbs. Males have much wider chests, necks, and general forebody structure. Males can weigh between 990–2470 lbs. Steller sea lion or Eumetopias jubatus males are further distinguished from females by broader and higher foreheads, flatter snouts, and a thick mane of coarse hair around their large necks.

The Steller sea lion or Eumetopias jubatus are skilled and opportunistic marine predators, feeding on a wide range of fish and cephalopod species. Important diet components include walleye pollock, Atka mackerel, halibut, herring, capelin, flatfish, Pacific cod, rockfish, sculpins, salmon, sand lance, and cephalopods such as various squid and octopus.
