The harp seal is extremely gregarious and gathers on the pack ice well offshore during March and April to breed. The main breeding grounds are off Newfoundland and off Jan Mayen Land in the Arctic. During the breeding season, in the days of their abundance, they gathered in enormous closely packed herds, sometimes containing several hundred thousand animals and covering the ice for miles.

From all accounts it is evident that originally there were millions of these animals in the North Atlantic and Arctic Oceans. Their gregarious habits made them an easy prey, and the value of their skins and blubber formed the basis for a great industry. Hundreds of vessels were sent out from north European and American ports and nearly 1,000,000 harp seals were killed during each breeding season. This tremendous slaughter and its attendant waste has resulted in the disappearance of these seals from many of their former haunts and has alarmingly reduced their numbers everywhere. Some are still killed off the coast of Newfoundland, but the sealing industry, now insignificant as compared with its former estate, is practically dead.

The hunting of harp and other seals on the pack ice is an occupation calling for such splendid qualities of virile hardihood in the face of constant danger to life that its brutality has been little considered. In this perilous work great numbers of hunters have been cast away and frozen miserably on the drifting ice and many a sealing ship has been lost with all hands.
Off Newfoundland the young harp seal is born early in March, wearing a woolly white coat. At first it is tenderly cared for by its mother, but before the end of April it has learned to swim and is left to care for itself. The young do not enter the water until they are nearly two weeks old and require several days of practice before they learn to swim well. The adults are notable for their swiftness in the water. In the tremendous herds of these seals the continual cries uttered by old and young is said to produce a steady roar which may be heard for several miles. Their food is mainly fish. Man is their worst enemy, but they are also preyed upon by sharks and killer whales.
