Phoca groenlandica, commonly known as the harp seal, is a marine mammal found primarily in the North Atlantic and Arctic Oceans. These seals are easily recognizable by their distinctive black markings on a light gray coat. Adult harp seals can weigh between 300 to 400 pounds and measure about 5 to 6.5 feet in length. Harp seals are known for their migratory behavior, often traveling long distances between breeding and feeding grounds. They primarily feed on fish and invertebrates, using their sensitive whiskers to detect prey in the water. Their population is currently stable, although they face threats from climate change and hunting.
