ResumoThe harbor seal, though normally an animal of open water, ranges as far as 79°N on Ellesmere Island. It remains in the Canadian arctic the year round by residing in swiftly flowing water, both tidal and fresh, and at the edge of the fast ice. It actively ascends rivers, often far from the sea, and will live in lakes the year round where open water is available. This ability suggests that the supposedly land-locked race P. v. mellonae from Upper and Lower Seal Lakes, Ungava, may not have been isolated for any great time and casts doubt on the assertion that subspeciation has occurred from long isolation (5500 years ± 2500) during post-glacial uplift.
