An eared seal, otariid, or otary is any member of the marine mammal family Otariidae, one of three groupings of pinnipeds. They comprise 15 extant species in seven genera (another species became extinct in the 1950s) and are commonly known either as sea lions or fur seals, distinct from true seals (phocids) and the walrus (odobenids).
Sea lions are pinnipeds characterized by external ear flaps, long foreflippers, the ability to walk on all fours, short and thick hair, and a big chest and belly is quite interesting.

The largest of the eared seals, Steller sea lions are quick swimmers, about as fast as the smaller California sea lions. Glide velocity of individual Steller sea lions has been measured as 2.9–3.4 meters or 1.2–1.5 body lengths per second, which is close to the optimal swim velocity of 1.4 body lengths per second based on the minimum cost ...
Skull, female. The South American sea lion is among the largest of and most sexually dimorphic of the eared seals. Males measure up to 3 m (9.8 ft) in length with a weight of 350 kg (770 lb) while females reach a length 2 m (6 ft 7 in) and reach 150 kg (330 lb) in weight. Pups are born 0.86 m (2 ft 10 in) long and weigh 12–15 kg (26–33 lb).

Its natural habitat ranges from southeast Alaska to central Mexico, including the Gulf of California. California sea lions are sexually dimorphic; males are larger than females, and have a ...
Fur seals and sea lions are closely related and commonly known together as the "eared seals". 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 ...
Pinniped. Pinnipeds (pronounced / ˈpɪnɪˌpɛdz /), commonly known as seals, [a] are a widely distributed and diverse clade of carnivorous, fin -footed, semiaquatic, mostly marine mammals.
