The family Otariidae (Order Carnivora) contains the 15 extant species of fur seals and sea lions. Traditional classification of the family into the subfamilies Arctocephalinae (fur seals) and Otariinae (sea lions) is not supported, with the fur seal Callorhinus ursinus having a basal relationship relative to the rest of the family.

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 ().
While sea lions and seals are both pinnipeds, meaning that they have flippers for feet, there are some key differences between them. For example, sea lions have small flaps for outer ears while so ...
Pinnipedia (seals, sea lions, and walruses clade) is a widely distributed and diverse group of semiaquatic marine mammals which is closely related to an extinct group of pinnipeds, Enaliarctos. While support for the monophyly of pinnipeds is strong, the relationship of pinnipeds to terrestrial mammals is still unclear.
The most common pinniped species kept in captivity is the California sea lion as it is abundant and easy to train. [153] These animals are used to perform tricks and entertain visitors. [154] Other species popularly kept in captivity include the grey seal and harbor seal. Larger animals like walruses and Steller sea lions are much less common ...
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 ...
The walrus's body shape shares features with both sea lions (eared seals: Otariidae) and seals (true seals: Phocidae). As with otariids, it can turn its rear flippers forward and move on all fours; however, its swimming technique is more like that of true seals, relying less on flippers and more on sinuous whole body movements.
