The seal is a marine mammal adapted to life in water and cold regions, with a hydrodynamic body that makes it an agile and efficient swimmer. It lives in seas, oceans, and near ice floes or rocky beaches, spending much of its time swimming and searching for food. Seals are carnivorous and feed mainly on fish, mollusks, and other marine organisms. They have limbs transformed into flippers that help them move through the water, and a thick layer of blubber under the skin that keeps them warm in cold waters. Seal pups are born near the water and initially depend on their mother for food and protection. As they grow, they learn to swim, dive, and hunt, developing the strength, coordination, and endurance essential for aquatic life.
