Which marine mammals breed on Bering Sea islands?

The islands of the Bering Sea serve as vital breeding grounds for several species of marine mammals. Specifically, the islands are known as breeding sites for the northern fur seal and the sea otter.1

The Pribilof Islands, located in the Bering Sea, are particularly significant as a breeding ground for approximately 800,000 northern fur seals, representing a large portion of the world's population. While other marine mammals such as walruses, various seal species, and sea lions inhabit the broader northern regions of the Bering Sea, the islands themselves are specifically identified as key breeding locations for fur seals and sea otters.21
