Eared seal

An eared seal is a pinniped in the family Otariidae, distinguished by external ear flaps and hind flippers that rotate forward for movement on land.

Pinniped: A marine mammal in the group that includes seals, sea lions, and walruses. Eared seals are one branch of this broader group of flippered marine mammals.
Quadrupedal locomotion: Movement using four limbs for support and propulsion. Eared seals can turn their hind flippers forward and move on all fours across land.
California sea lion: A sea lion species native to the eastern North Pacific, known for social colonies and trained displays. Its forward-rotating hind flippers make it a familiar example of land mobility in Otariidae.
True seal: A pinniped in the family Phocidae, lacking external ear flaps and hind flippers suited to walking on land. True seals generally move on land by undulating their bodies rather than walking on rotated hind flippers.
Marine protected area: A geographically defined ocean or coastal area managed for conservation. Protected waters can safeguard feeding grounds and haul-out sites used by eared seals.
Otariidae: The pinniped family comprising fur seals and sea lions. This is the family to which every eared seal belongs.
Aquatic locomotion: Movement through water by swimming, paddling, or other forms of propulsion. Eared seals use coordinated flipper strokes to travel efficiently between feeding and breeding sites.
Northern fur seal: A fur seal species that breeds on North Pacific islands and migrates widely at sea. Its dense underfur illustrates the insulation strategy that distinguishes fur seals from sea lions.
Walrus: A large tusked pinniped and the sole living member of the family Odobenidae. Walruses are the third major living pinniped lineage, distinct from both eared and true seals.
Bycatch: The unintended capture of non-target animals during fishing operations. Fishing gear can entangle eared seals and cause injury or death.
