There are four major breeding areas for the hooded seal: the Gulf of St. Lawrence; the "Front" east of Newfoundland; Davis Strait (between Greenland and northern Canada); and the West Ice near Jan Mayen. Male hooded seals are known to have several mates in a single mating season, following the hypothesis that they are polygynous.
Range maps are provided wherever possible; if a range map is not available, a description of the pinniped's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".
In the 1980s–1990s, takings of harp seals totaled 8,000–10,000, and annual catches of hooded seals totaled a few thousand between 1997 and 2001. [1] Norway accounts for all recent seal hunting in the West Ice, as Russia has not hunted hooded seals since 1995, and catches harp seals at the East Ice in the White Sea – Barents Sea .
Seals that breed on ice tend to have little or no sexual dimorphism. In Antarctic seals, there is some size bias in favor of females. Walruses and hooded seals are unique among ice-breeding species in that they have pronounced sexual dimorphism in favor of males. [29] [112] Northern fur seal breeding colony
In comparison to the two other major groups of marine or sea mammals, cetaceans and sirenians, pinnipeds are a relatively younger group having appeared about 24 to 38 million years ago and are still able to return on land to breed. The list of fossil taxa is based on mostly the historiographical data from Valenzuela-Toro and Pyenson (2019). [2]
Vagrant hooded seals also appear every now and again. [3] In 1995, continuous observations of North Atlantic right whale, being considered as functionally extinct in eastern North Atlantic were made, [4] followed by another possible sighting off La Gomera between 1998 and 1999. [5]
The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic ...
The Saimaa ringed seal is closely related to the Ladoga ringed seal, the populations likely became isolated from the Baltic ringed seal around the same time. The Saimaa ringed seal lives solely within Saimaa, a large freshwater lake in the regions of South Savo, South Karelia, and North Karelia in Finland. Current estimates place the size of ...
