Named common seal throughout Europe, this seal frequently observed around Long Island lives along the shores of eastern Canada, New England and in the winter, as far south as the Carolinas in a variety of habitats.
Unlike many other seal pups, harbor seals are able to swim from birth, although they are dependent on care and milk from the mother for 3 - 6 weeks before they venture out on their own.
While tending their young, harbor seal mothers are very protective and will sometimes push the pup beneath the surface or carry it on her shoulders to avoid danger.

In their warm bellies, seals host masses of worms, that produce phenomenal numbers of eggs, which are released into the water with the feces of the seal and act to enrich the zooplankton.
The relationship of seals and fish to photosynthesis in the ocean is rather like that of tree trunks in the forest: trunks and branches are living tree elements that do not capture the sun’s energy directly, but that have been built by drawing on materials produced by the specialized green leaf cells that do.

The true seals or earless seals are one of the three main groups of mammals within the seal suborder, Pinnipedia.
The phocid reproductive cycle is characterized by temporal and spatial separation between feeding and maternal investment; in other words, a pregnant female spends a long period of time foraging at sea, building up her fat reserves, and then returns to the breeding site and uses her stored energy reserves to provide milk for her pup.
Seals, like all marine mammals, need time to develop the oxygen stores, swimming muscles and neural pathways necessary for effective diving and foraging.

The virus was originally brought to Europe in 1988 by harbour seals travelling from Greenland, where it is endemic.
Other possibilities are that the seals caught the virus from mink or from grey seals, in which PDV is rarely fatal.
