northern fur seal

The northern fur seal (Callorhinus ursinus) is a migratory mammal found in northern seas, primarily breeding on the Pribilof and Komandor islands during the summer. These seals are known for their chestnut-colored underfur and are gregarious and vocal animals that feed on fish and other marine life. Adult males can reach up to 3.1 meters (10 feet) and weigh 300 kg (660 pounds), while females are smaller, reaching about 1.5 meters (5 feet) and weighing 60 kg (130 pounds).1

Historically, northern fur seals were extensively hunted for their fur, leading to protection measures in 1911. While populations recovered to about one million by the late 20th century, they have since been declining due to factors like overfishing of their prey and environmental changes. The Pribilof Islands are a significant breeding ground for about two-thirds of the world's northern fur seal population.12
