Taxonomy

File:Whale comparison Public Domian photo by Charles Melville Scammon for coast of North America (1872).jpg (1825–1911).]]

Most modern classifications split the minke whale into two species:

Taxonomists further categorize the common minke whale into two or three subspecies; 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 (Scammon 1872), B. minimia (Rapp, 1837), and B. rostrata (Fabricius, 1780). There is one synonym for B. bonaerensisB. huttoni (Gray 1874).

Writing in his 1998 classification, Rice recognized two of the subspecies of the common minke whale – B. a. scammoni (Scammon's minke whale) and a further taxonomically unnamed subspecies found in the Southern Hemisphere, the dwarf minke whale (first described by Best as "Type 3," 1985).{{cite journal | last1 = Best | first1 = P | year = 1985 | title = External characters of southern minke whales and the existence of a diminutive form | journal = Scientific Reports of the Whales Research Institute | volume = 36 | pages = 1–33 }}

The minke whale has a black/gray/purple color.{{clarify|date=May 2017}} Common minke whales (Northern Hemisphere species) 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 typically live between 30–50 years, but in some cases, they may live for up to 60 years. They have a gestation and calving period of approximately 10–11 months and 2 years, respectively.{{cite journal|author=Song, K.-J. |year=2016 |title=Current stock situation and measures for the management and conservation of minke whales (Balaenoptera acutorostrata) in Korean waters |journal=Ocean & Coastal Management |volume=119|pages=164–168|doi=10.1016/j.ocecoaman.2015.10.011}}{{cite book|last1=John E.|first1=Reynolds|title=Biology of Marine Mammals|publisher=Smithsonian|isbn=9781588344205|page=257|url=https://www.google.co.kr/books/edition/Biology_of_Marine_Mammals/lKVqBgAAQBAJ?hl=en&gbpv=1&dq=Minke+whale+60+years&pg=PA257&printsec=frontcover|access-date=8 April 2025|language=en|date=2013}}{{cite web |last1=Alastair|first1=Birtles|title=Dwarf minke whales in the Great Barrier Reef|page=2 |url=http://rrrc.org.au/wp-content/uploads/2014/03/05-2002-Dwarf-minke-whales-in-the-Great-Barrier-Reef.pdf|access-date=May 23, 2025}}

Minke whales have a digestive system composed of four compartments with a high density of anaerobic bacteria throughout. The presence of the bacteria suggests minke whales rely on microbial digestion to extract nutrients provided by their food.{{Cite journal|date=1995-01-01|title=Digestive physiology of minke whales|journal=Developments in Marine Biology|language=en|volume=4|pages=351–359|doi=10.1016/S0163-6995(06)80036-3|issn=0163-6995|last1=Mathiesen|first1=S.D.|last2=Aagnes|first2=T.H.|last3=Sørmo|first3=W.|last4=Nordøy|first4=E.S.|last5=Blix|first5=A.S.|last6=Olsen|first6=M.A.|isbn=9780444820709}}

As with most Mysticetes, the auditory system for the minke whale is not well understood. However, magnetic resonance imaging points to evidence that the minke whale has fat deposits in their jaws intended for sound reception, much like Odontocetes.{{cite journal | last1 = Yamato | first1 = Maya | last2 = Ketten | first2 = Darlene R. | last3 = Arruda | first3 = Julie | last4 = Cramer | first4 = Scott | last5 = Moore | first5 = Kathleen | date = June 2012 | title = The auditory anatomy of the minke whale (Balaenoptera acutorostrata): a potential fatty sound reception pathway in a baleen whale |journal=Anatomical Record |volume=295|issue=6|pages=991–998|doi=10.1002/ar.22459 |pmc=3488298|pmid=22488847}}

=Migration=

Both species undertake seasonal migration routes to the poles during spring and towards the tropics during fall and winter. The difference between the timing of the seasons may prevent the two closely related species from mixing.Glover KA, Kanda N, Haug T, Pastene LA, Øien N, Goto M, et al. (2010) Migration of Antarctic Minke Whales to the Arctic. PLoS ONE 5(12): e15197. https://doi.org/10.1371/journal.pone.0015197 A long-term photo identification study on the British Columbian and Washington coasts showed that some individuals travel as far as 424 km north in the spring, and 398 km south to warmer waters in the autumn. Many specifics about migration in this species still remain unclear.{{cite web|publisher=B.C.

=Reproduction=

{{See also|Whale reproduction}}

The gestation period for minke whales is ten months, and calves measure {{convert|2.4|to|2.8|m|ft|abbr=on}} at birth. The newborns nurse for five to ten months. Breeding peaks during the summer months. Calving is thought to occur every two years.{{cite web |url=http://www.acsonline.org/factpack/MinkeWhale.htm |title=Home |access-date=2016-02-08 |url-status=dead |archive-url=https://web.archive.org/web/20120127220325/http://www.acsonline.org/factpack/MinkeWhale.htm |archive-date=2012-01-27 }} American Cetacean Society: Minke Whale

The timing of conception and birth varies between region.

In the North Atlantic, conception takes place from December to May with a peak month of February with birth taking place from October to March with a peak in December. In the North Pacific off Japan there appears to be two phases of conception, the majority of which occurs from February to March but also from August to September, with births occurring from December to January and June to July. In the Yellow Sea stock these two phases have not been noted with conception occurring from July to September and birth peaking from May to June.

In the Southern Hemisphere conception takes place from June to December with a peak in August and September. Peak birth time occurs from July to August.{{cite web |url=http://www.projectminke.com/biology2.htm |title=Minke Whales - Reproduction |access-date=2018-05-28 |url-status=dead |archive-url=https://web.archive.org/web/20161022044506/http://www.projectminke.com/biology2.htm |archive-date=2016-10-22 }}

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.{{Citation needed|date=August 2007}} In the 19th century, they were considered too small 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.Joseph Horwood, Biology and exploitation of the minke whale (CRC Press) 1989:3.

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 small size. However, by the early 1970s, following the overhunting of larger 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 smaller 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.{{citation needed|date=May 2018}} Between November 2017 and March 2018, Japan reported catches of a total of 333 Minke whales, of which 122 were pregnant females.{{cite news|title=Japanese whale hunters kill 122 pregnant minke|url=https://www.bbc.com/news/world-asia-44307396|publisher=BBC News|date=30 May 2018}}

Although Norway initially followed the moratorium, they had placed an objection to it with the IWC and resumed a commercial hunt of the Common minke whale in 1993. The quota for 2006 was set at 1,052 animals, but only 546 were taken.{{cite web|url=https://www.lofotposten.no/lokale_nyheter/article2241060.ece?ns_campaign=article&ns_mchannel=recommend_button&ns_source=facebook&ns_linkname=facebook&ns_fee=0|title=Tok bare halve hvalkvoten|date=16 August 2006|website=www.lofotposten.no|access-date=14 February 2019}} The quota for 2011 was set at 1286.{{cite web|url=http://www.p4.no/story.aspx?id=388242 |title=Samme hvalkvote som i år|website=www.p4.no}} 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,{{cite journal| url=https://www.newscientist.com/article/mg19426034.100-high-value-of-whale-meat-costs-minkes-in-korea.html| journal=New Scientist| issue=2603|date=10 May 2007| pages= 10| first=Peter| last= Aldhous| title=High value of whale meat costs minkes in Korea| doi=10.1016/S0262-4079(07)61160-9| volume=194| url-access=subscription}} approximately twice the officially reported number. This raised concerns that some whales were being caught deliberately.

In July 2019, Japan resumed commercial whaling activities. The permitted catch for the initial season (July 1 – December 31, 2019) is 227 whales, of which 52 can be minke.{{cite web|url=https://www.cnn.com/2019/07/02/asia/japan-first-whale-catch-31-years-trnd/index.html|title=Japan's first commercial whale catch in 31 years|access-date=2 July 2019|website=www.cnn.com|date=2 July 2019 }}

Whale watching

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).

In the northern Great Barrier Reef (Australia), a swim-with-whales tourism industry has developed based on the June and 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 [http://www.gbrmpa.gov.au/ 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 Haro Strait of British Columbia and Washington state.
