Pinnipeds are a group of marine mammals that include seals, sea lions, and walruses. They are known for their flippers, which help them swim efficiently in the ocean. Pinnipeds are found in various habitats, from icy polar regions to temperate coastlines, and they often come ashore to rest, breed, and give birth. These animals are excellent hunters, primarily feeding on fish and other marine creatures. Pinnipeds have a layer of blubber that keeps them warm in cold waters. They are social animals, often seen in large groups, and play an important role in the marine ecosystem as both predators and prey.
