Baby seals are a type of marine mammal that belong to the family of true seals. They are also known as pups, and they are characterized by their short fur, big eyes, and small size. The term 'PUP' is used to refer to a baby seal, and it is also used to describe a young seal of any age. A baby seal's coat is usually gray or white in color, and they have a distinctive black spot on their forehead. Sigil is another term for a baby seal, and it refers to the unique pattern of spots or markings on its fur. Pups are the youngest members of the seal family, and they are born with a thick layer of blubber to help them stay warm in cold water.
