Seals are a type of furry sea mammal that are found in many parts of the world. They have a streamlined body shape and flippers, which help them to swim quickly and gracefully in the water. Seals are carnivores, and they feed on fish, squid, and other marine life. They are also known for their loud vocalizations, which can be heard from far away. Seals are social animals, and they often form large colonies on land or in the water.
