Pinnipeds are a group of marine mammals that include seals, sea lions, and walruses. They are characterized by their flippers, which make them well-adapted for swimming. Pinnipeds are found in various oceans and coastal regions around the world, often resting on land or ice. These animals are known for their social behavior, often living in large colonies. Pinnipeds primarily feed on fish and other marine organisms. They have a layer of blubber that helps insulate them in cold waters, making them efficient hunters in their aquatic environments.
