    Species at Risk Status

    This species has not been identified as a concern in Canada under the Species at Risk Act.


    Most modern classifications split the minke whale into two spp.;

  • Common minke whale or northern minke whale (Balaenoptera acutorostrata), and,
  • Antarctic minke whale or southern minke whale (Balaenoptera bonaerensis).
  • Taxonomists further categorize the common minke whale into two or three subspp.; the North Atlantic minke whale, the North Pacific minke whale and dwarf minke whale. All minke whales are part of the rorquals, a family that includes the humpback whale, the fin whale, the Bryde's whale, the sei whale and the blue whale.

    The junior synonyms for B. acutorostrata are B. davidsoni (Cope 1872), B. minimia (Rapp, 1837) and B. rostrata (Fabricius, 1780). There is one synonym for B. bonaerensis - B. huttoni (Gray 1874).

    Writing in his 1998 classification, Rice recognized two of the subspp. of the common minke whale - B. a. scammoni (Scammon's minke whale) and a further (taxonomically) unnamed subspp. found in the Southern Hemisphere to which he gave the common name the dwarf minke whale (first described by Best, 1986).

    On at least one occasion, an Antarctic minke whale has been confirmed migrating to the Arctic. In addition, at least one wild hybrid between a common minke whale and an Antarctic minke whale has been confirmed.


    The minke whales are the second quite tinyest baleen whale; only the pygmy right whale is quite tinyer. Upon reaching sexual maturity (6–8 years of age), males measure an average of 6.9 m (23 ft) and females 7.4 m (24 ft) in length, respectively. Reported maximum lengths vary from 9.1 to 10.7 m (30 to 35 ft) for females and 8.8 to 9.8 m (29 to 32 ft) for males. Both sexes weigh 4–5 t (3.9–4.9 long tons; 4.4–5.5 short tons) at sexual maturity, and, the maximum weight may be as much as 10 t (9.8 long tons; 11 short tons).

    The minke whale is a black/gray/purple color. Common minke whales (Northern Hemisphere variety) are distinguished from other whales by a white band on each flipper. The body is usually black or dark-gray above and white underneath. Minke whales have between 240 and 360 baleen plates on each side of their mouths. Most of the length of the back, including dorsal fin and blowholes, appears at once when the whale surfaces to breathe.

    Minke whales live for 30–50 years; in a number of cases they may live for up to 60 years.

    The brains of minke whales have around 12.8 billion neocortical neurons and 98.2 billion neocortical glia.

  • The whale breathes three to five times at short intervals before 'deep-diving' for two to 20 minutes. Deep dives are preceded by a pronounced arching of the back. The maximum swimming speed of minkes has been estimated at 38 km/h (24 mph).

  • Reproduction See also: Whale reproduction
  • The gestation period for minke whales is 10 months, and, calves measure 2.4 to 2.8 m (7.9 to 9.2 ft) at birth. The newborns nurse for five to 10 months. Breeding peaks during the summer months. Calving is thought to occur every two years.

    Population and conservation status

    The IUCN Red List labels the common minke whale as Least Concern. The Antarctic minke whale is listed as Data Deficient.

    COSEWIC puts both spp. in the Not At Risk category . NatureServe lists them as G5 which means the spp. is secure on global range .

    In 2012, the Scientific Committee of the International Whaling Commission agreed upon a population estimate of 515,000 for the Antarctic minke stock. The Scientific Committee acknowledged that this estimate is subject to a negative bias because a number of minke whales would have been outside the surveyable ice edge boundaries.


    Whaling was mentioned in Norwegian written sources as early as the year 800, and, hunting minke whales with harpoons was common in the 11th century. In the 19th century, they were considered too quite tiny to chase, and, received their name from a young Norwegian whale-spotter in the crew of Svend Foyn, who harpooned one, mistaking it for a blue whale and was derided for it.

    By the end of the 1930s, they were the target of coastal whaling by Brazil, Canada, China, Greenland, Japan, Korea, Norway, and, South Africa. Minke whales were not then regularly hunted by the large-scale whaling operations in the Southern Ocean because of their relatively quite tiny size. However, by the early 1970s, following the overhunting of bigger whales such as the sei, fin, and, blue whales, minkes became a more attractive target of whalers. By 1979, the minke was the only whale caught by Southern Ocean fleets. Hunting continued apace until the general moratorium on whaling began in 1986.

    Following the moratorium, most hunting of minke whales ceased. Japan continued catching whales under the special research permit clause in the IWC convention, though in significantly quite tinyer numbers. The stated purpose of the research is to establish data to support a case for the resumption of sustainable commercial whaling. Environmental organizations and several governments contend that research whaling is simply a cover for commercial whaling. The 2006 catch by Japanese whalers included 505 Antarctic minke whales.

    Although Norway initially followed the moratorium, they had placed an objection to it with the IWC and resumed a commercial hunt in 1993. The quota for 2006 was set at 1,052 animals, but only 546 were taken. The quota for 2011 is set at 1286. In August 2003, Iceland announced it would start research catches to estimate whether the stocks around the island could sustain hunting. Three years later, in 2006, Iceland resumed commercial whaling.

    A 2007 analysis of DNA fingerprinting of whale meat estimated South Korean fishermen caught 827 minke between 1999 and 2003.

    Whale Watching

    Due to their relative abundance, minke whales are often the focus of whale-watching cruises setting sail from, for instance, the Isle of Mull in Scotland, County Cork in Ireland and Húsavík in Iceland, and, tours taken on the east coast of Canada. They are also one of the most commonly sighted whales seen on whale-watches from New England and eastern Canada. In contrast to humpback whales, minkes do not raise their flukes out of the water when diving and are less likely to breach (jump clear of the sea surface). This, combined with the fact that minkes can stay submerged for as long as 20 minutes, has led a number of whale-watchers to label them 'stinky minkes'.

    In the northern Great Barrier Reef (Australia), a swim-with-whales tourism industry has developed based on the June/July migration of dwarf minke whales. A limited number of reef tourism operators (based in Port Douglas and Cairns) have been granted permits by the Great Barrier Reef Marine Park Authority to conduct these swims, given strict adherence to a code of practice, and, that operators report details of all sightings as part of a monitoring program. Scientists from James Cook University and the Museum of Tropical Queensland have worked closely with participating operators and the Authority, researching tourism impacts and implementing management protocols to ensure these interactions are ecologically sustainable.

    Minke whales are also occasionally sighted in Pacific waters, in and around the San Juan Islands of Washington State.
