Harbor Seal Haulout Distribution

Habitat

Coastal waters to about 10 miles offshore, bays, harbors, coastal rivers, lakes. Most common in protected areas such as bays or inlets. Some frequently occur in freshwater bodies connected to the ocean and possibly resident freshwater in Lake Iliama (Alaska). Haul outs on isolated mudbanks, rocky islets, rocky or sandy shores, intertidal ledges, reefs, and glacial and sea ice (Scheffer 1958, Boulva and McLaren 1979, Johnson and Jeffries 1977, Burns and Gol’tsev 1984, Hoover 1988, Reeves et al. 1992). Pups are born on shore, often in an intertidal area; secluded sites and areas beyond strong wave action (NatureServe 2007b).
