The eared seals (or walking seals), family Otariidae, are the fur seals and the sea lions. These are barrel shaped marine mammals, adapted to a semi-aquatic lifestyle. They feed and travel in the water but breed and largely rest on land (or, in some cases, on ice). They are slightly less adapted to the aquatic lifestyle than are the true seals. They are tied to rich upwelling zones close to their breeding sites and have greater maneuverability (in water and land) than true seals.
On average, the mature male eared seals are almost three times larger than the female, making them the most sexually dimorphic of all mammals. [1]
