Western Atlantic Harbor Seal - Phoca vitulina concolor (DeKay, 1842)
The harbor seals living in fresh water lakes in Canada are occasionally assigned to a separate subspecies, Phoca vitulina mellonae (Doutt, 1942), the Ungava seal, but its status as a subspecies is doubtful. Usually these seals are included in P. v. concolor (DeKay, 1842). The length of males ranges from 150 to 180 cm and the weight from 55 to 105 kg. Females measure 120-150 cm and weigh 45-87 kg. Pups measure 70-90 cm at birth and weigh 9-11 kg. The color of the harbor seal is variable: grey to brownish grey with black spots.
The Western Atlantic harbor seal ranges from Maine north to Ellesmere Island in the Canadian Arctic and west to the Hudson Bay. This range includes Nova Scotia, Newfoundland, Labrador and Baffin Island. The seal is also found in Greenland. The Ungava seal can be found in the fresh water Seal Lakes in Ungava, Canada.
They feed mainly on local fish, including herring and flounder.
The population dynamics parameters are probably similar to those of P. v. vitulina. Females become mature at the age of 3. The pregnancy rate is on average 87%. Gestation lasts 10½-11 months, including a delay of implantation of 2 months. Lactation lasts 4-6 weeks. Longevity is 35 years for females and 25 years for males. Adult mortality is probably about 13%. The preweaning mortality is 17% and subadult mortality 16%.
