* Head shape: Harp seals have a distinctive head shape with a rounded forehead and a slightly flattened snout. Their eyes are large and dark, and they have a keen sense of vision both above and below water.
* Coat color: Harp seals are born with a white coat that gradually darkens to a silvery gray as they age. Their coats are covered in a thick layer of blubber that helps to insulate them from the cold Arctic waters.
* Vocalizations: Harp seals are known for their vocalizations, which include barking, growling, and hooting sounds. They use these sounds to communicate with each other and to attract mates during the breeding season.
* Migration patterns: Harp seals are known for their long migrations, which can cover thousands of miles. They migrate south in the winter to breed and give birth in the warmer waters of the Gulf of St. Lawrence and the White Sea. In the summer, they migrate north to the Arctic Ocean to feed on fish, shrimp, and other prey.
