Bowhead whale
The bowhead whale (*Balaena mysticetus*) is a baleen whale that lives year-round in Arctic and subarctic waters.
The bowhead whale (*Balaena mysticetus*) is a baleen whale that lives year-round in Arctic and subarctic waters. It is known for its massive bow-shaped skull, thick blubber, long baleen plates, and exceptional lifespan, which may exceed 200 years. The species is closely associated with sea ice and is important to Indigenous subsistence in parts of the Arctic.
Description
Bowhead whales are large, dark baleen whales with a prominent arched upper jaw and a huge skull that can make up a large share of body length. They have thick blubber and long baleen plates adapted for life in cold waters. Adults average about 15 metres in length and weigh 60–80 tonnes.
Habitat and range
The species has a circumpolar distribution in the Arctic and subarctic, including the Bering, Chukchi, and Beaufort seas and waters around the Canadian Arctic. Their movements are closely tied to sea ice conditions, and they are the only baleen whales that spend their entire lives in Arctic and near-Arctic waters.
Feeding and behaviour
Bowhead whales are filter feeders that consume zooplankton such as copepods and krill by filtering water through baleen plates. They are also known for complex vocalisations and for their ability to travel through or near sea ice, using their massive reinforced skull to break through ice.
Conservation
Bowhead whales were heavily affected by historic commercial whaling. The species is now listed as least concern globally by the IUCN, but some regional populations remain smaller and are treated as endangered or depleted under certain conservation systems.
Human importance
Bowhead whales remain important to subsistence hunting and cultural life in parts of the Arctic, especially among Indigenous communities in Alaska and Canada. In Canada, they are part of the marine wildlife of the Arctic, particularly in Nunavut and adjacent northern waters, and are significant to Inuit subsistence, culture, and food security.
Key facts
- Bowhead whales are the only baleen whales that spend their entire lives in Arctic and near-Arctic waters.
- They use a massive reinforced skull to break through sea ice.
- The species is among the longest-lived mammals, with estimates exceeding 200 years.
- Bowhead whales are culturally and nutritionally important to northern Indigenous communities in Alaska and Canada.
Bowhead whales are part of the marine wildlife of Canada’s Arctic, especially in Nunavut and adjacent northern waters. They are also significant to Inuit subsistence, culture, and food security.
