The Northern Fur Seal is a marine mammal from the eared seal family. It lives in cold waters of the northern Pacific Ocean and is known for its dense fur.
The Northern Fur Seal differs from true seals by noticeable ear flaps and very dense fur. It is important for the ocean as a fish hunter and part of the food chain.
