The Steller Sea Lion or the Northern Sea Lion belongs to the Otariidae family, also known as eared seal. It has external ears, which are closed when it goes into the water, while its flippers or hind feet point towards the front, quite in contrast to the true seal, or Phocidae, which is earless while the flippers point towards the back.
Amongst the otariids, the Steller Sea Lion is the largest in size, while amongst the pinnipeds, which means fin-footed, it is the fourth largest. The habitat of this mammal is the coastal regions of northern Pacific. They gather on haulouts and rookeries when they are not in the water.
The female comes later and generally gives birth to a single pup that had been conceived the previous year. The duration of pregnancy is 11½ months, while the mother lactates for 1 - 3 years. Mating takes place soon after the birth of the pups, in June and July.
The Steller Sea Lion's predators include us humans, killer whales, and sharks.
