Pagophilus groenlandicus
Harp seals are born on pack ice in fluffy white coats that camouflage them for the first two weeks, then moult to silver with a black harp-shaped saddle. They are superb divers, feeding on small schooling fish and krill, and they migrate with the ice edge each season. Warming winters with poor ice have caused years of mass pup mortality in the northwest Atlantic, and hunting remains controversial in Canada.
