Harp Seals (also known as Saddleback Seals due to markings on their back that appear like a saddle) are native to colder waters in the Arctic and North Atlantic. These seals can dive up to 1,300 feet and can remain underwater for 16 minutes, feasting on an extremely wide variety of fish and crustaceans. They mate during a short span of time in the winter when pack ice (a thick layer of ice) is available to give birth to and nurse their young. They will then travel sometimes up to 3,100 miles roundtrip once summer hits to feed in colder waters.
