The Juan Fernández fur seal can be spotted only in the waters around the islands of the archipelago they are named after, as well as in the even more isolated San Felix or Desventuradas islands to the north. These are the world’s second-smallest fur seals, after Galápagos fur seals. Small is relative, however, and male seals average around 135 kilograms (298 pounds). Fur seals are distinguished from other seals by the thick fur coats that insulate them in the cold waters where they are typically found. They also, unlike other seals, have external ear flaps and walk on land using their front flippers, rather than their chest, for support.
