The Northern Sea Lion, also known as the Steller Sea Lion, is a large marine mammal found along the coasts of the North Pacific Ocean. They are characterized by their robust bodies, external ear flaps, and long front flippers. Adult males can weigh up to 1,000 pounds, while females are smaller, averaging around 300 pounds. Their fur ranges from light tan to dark brown, and they have a thick layer of blubber for insulation. These sea lions primarily feed on fish, squid, and other marine organisms. They are social animals, often seen in large groups on rocky shores or beaches. The Northern Sea Lion is known for its vocalizations, which include barks and growls. Conservation efforts are in place to protect their populations, as they face threats from habitat loss and fishing activities.
