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 ().
Otarioidea is a superfamily of pinnipeds that includes the families Odobenidae, Otariidae and their stem-relatives. [1] [2] In the past when the pinnipeds were considered to be a diphyletic group of marine mammals, a few points of cranial and dental morphology suggested that the otarioids originated from a line of bears.

The earless seals, phocids, or true seals are one of the three main groups of mammals within the seal lineage, Pinnipedia.All true seals are members of the family Phocidae (/ ˈ f oʊ s ɪ d iː /).
Size ranges from about 1.5 m, 64 kg in the male Galapagos fur seal (also the smallest pinniped) to 2.5 m, 180 kg in the adult male New Zealand fur seal. Most fur seal pups are born with a black-brown coat that molts at 2–3 months, revealing a brown coat that typically gets darker with age.
A member of this group is called a pinniped or a seal. [ a ] They are widespread throughout the ocean and some larger lakes, primarily in colder waters. Pinnipeds range in size from the 1.1 m (3 ft 7 in) and 50 kg (110 lb) Baikal seal to the 6 m (20 ft) and 3,700 kg (8,200 lb) male southern elephant seal , which is also the largest member of ...
Sea lions, with three groups of pinnipeds, have multiple breeding methods and habits over their families but they remain relatively universal. Otariids, or eared sea lions, raise their young, mate, and rest in more earthly land or ice habitats. Their abundance and haul-out behavior have a direct effect on their on land breeding activity.
Pinnipeds are flippered marine mammals belonging to three related families in the order Carnivora, the Phocidae (earless seals or true seals), ...
