アメリカ内務省さんのインスタグラム写真 - (アメリカ内務省Instagram)「This Northern fur seal has our seal of approval. These "sea bears" are known for the dense fur covering their bodies to keep them warm in the frigid waters where they live. And by dense, we mean 300,000 hairs per square inch! Northern fur seals are pelagic, spending most of their lives in the open ocean and only using certain offshore islands for pupping and breeding. They primarily reside on Alaska Maritime National Wildlife Refuge’s Pribilof Islands and Bogoslof Islands, but their range extends to two islands off California.
