Otariinae
Otariinae is a subfamily of the Otariidae family, comprising the eared seals commonly known as sea lions. Members possess external ear flaps, elongated bodies, and large forelimbs used for propulsion in water and on land. They can rotate their hind limbs forward, enabling comparatively agile locomotion on terrestrial surfaces, a trait that distinguishes them from true seals (Phocidae). Otariinae species inhabit temperate and subpolar coastal waters in both hemispheres, often returning to beaches, islands, or cliff ledges to breed.
Taxonomy in Otariinae includes several extant genera: Otaria (the South American sea lion, Otaria byronia), Eumetopias
Ecology and behavior within Otariinae centers on seasonal rookeries where males defend territories and harems while
Conservation status varies by species and region. Otariinae populations face threats from bycatch in fisheries, habitat
