PinnipedsOtariidae refers to the Otariidae, the family of eared seals within pinnipeds, which includes the fur seals and sea lions. They are distinguished from true seals by external ear flaps, more developed foreflippers used for propulsion, and the ability to rotate their hind limbs forward to walk on land. The family is divided into two subfamilies, Otariinae (sea lions) and Arctocephalinae (fur seals). Genera commonly encountered include Otaria, Eumetopias, Zalophus, Callorhinus, and Arctocephalus.

Otariidae species inhabit temperate and subpolar regions of the Pacific Ocean and the Southern Ocean, with major breeding rookeries on islands and along coastal shores. They are highly social, forming colonies that can be quite vocal during the breeding season. In the open ocean they travel long distances to forage, primarily on fish and squid, though diets vary by species and region.

Reproduction in Otariidae is typically seasonal and often polygynous. Males establish territories during the breeding season to attract females, while females give birth to one pup and provide extended maternal care before weaning. Pups are dependent on their mothers for nourishment and protection during early development.

Conservation status within Otariidae varies by species. Some populations remain relatively stable, while others are threatened by habitat destruction, entanglement in fishing gear, oil spills, and climate change. International and national protections exist for many species, reflecting ongoing conservation concerns and management efforts.
