Fur seals are marine mammals belonging to the family Otariidae, which also includes sea lions. They are known for their thick fur, which helps keep them warm in cold ocean waters. Fur seals are found in various regions, including the Antarctic, North Pacific, and South American coasts. They are agile swimmers, using their strong front flippers to propel themselves through the water. These animals are social and often gather in large colonies on rocky shores or beaches. Fur seals primarily feed on fish, squid, and crustaceans. They are also known for their playful behavior, often seen leaping and diving in the water.
