Harbor seals are nonmigratory marine mammals found in sub-arctic and temperate waters of the North Atlantic and North Pacific Oceans and contiguous seas. In the North Pacific, their distribution extends from San Ignacio Lagoon, Mexico, around the North Pacific Rim to Hokkaido, Japan, and into the Bering Sea to the Pribilof Islands and northern Bristol Bay. They generally are found near shore in estuaries or protected waters but may range far out to sea in deep pelagic waters or up freshwater rivers and into lakes.
