By Ethan Anderson| Reviewed by Olivia Bennett, Standards & Fact-Checking Lead| Updated July 26, 2026|2 min read| Fact-checked

The minke whale is a species complex of baleen whale and the smallest of the rorquals. It includes the common minke whale (Balaenoptera acutorostrata) and the Antarctic minke whale (Balaenoptera bonaerensis), both widely distributed in ocean waters. In Canadian waters, minke whales are found in the North Atlantic and North Pacific, making them relevant to Canadian marine wildlife and conservation.

Taxonomy and classification

Minke whales are baleen whales (mysticetes) and belong to the rorqual family. Two species are widely recognized: the common minke whale (Balaenoptera acutorostrata) and the Antarctic minke whale (Balaenoptera bonaerensis).

Physical characteristics

Minke whales are the smallest of the rorqual whales, with a streamlined body and pointed snout. Adults typically reach lengths of about 6.5 to 10 metres and can weigh around 10 tons.

Range and habitat

Minke whales are found in oceans worldwide, from tropical to polar regions. The common minke whale inhabits the Northern Hemisphere, including the North Atlantic and North Pacific waters off Canada, while the Antarctic minke whale is primarily found in the Southern Hemisphere.

Feeding and behaviour

Minke whales are baleen whales that filter-feed using baleen plates. Their diet consists mainly of small fish and krill. They are known for their speed and inquisitive behaviour, often approaching boats.

Conservation

The common minke whale is listed as Least Concern and its population is considered stable. The Antarctic minke whale is assessed separately and is listed as Near Threatened.

Key facts

  • Minke whales are the smallest of the rorqual whales.
  • They are baleen whales that filter-feed using baleen plates rather than teeth.
  • There are two recognized species: the common minke whale and the Antarctic minke whale.
  • They are widely distributed in oceans around the world.
  • The common minke whale is generally considered stable and listed as Least Concern.

Canadian context

Minke whales are found in North Atlantic and North Pacific waters that border Canada, making them relevant to Canadian marine wildlife, whale watching, and marine conservation.
