Steller's sea lion, also known as Eumetopias jubatus, is a large marine mammal found in the North Pacific Ocean. The sea lion is characterized by its dark brown fur, prominent whiskers, and broad muzzle. Along with the name Steller's sea lion, the mammal is also referred to as Northern sea lion, Alaskan sea lion, and Pacific sea lion. These synonyms are often used interchangeably to refer to the species, although Steller's sea lion is the scientific name. The sea lion is a social animal that gathers in large colonies on rocky shores to breed, molt, and rest. Despite being a protected species, Steller's sea lions face threats from overfishing and habitat destruction, making conservation efforts essential for its survival.
