Minke Whale
The term “Minke Whale” is used to refer to two closely related species of baleen whale: the Northern and Southern Minke Whale. It is the second smallest baleen whale, but still quite a large animal overall.
Class: Mammalia
Order: Artiodactyla
Infraorder: Cetacea
Family: Balaenopteridae
Genus: Balaenoptera
Species: B. acutorostrata, B. bonaerensis
Common Names: Minke Whale, Lesser Rorqual, Northern Minke Whale (B. acutorostrata), Southern Minke Whale (B. bonaerensis), Common Minke Whale (B. acutorostrata), Antarctic Minke Whale (B. bonaerensis)
Like most other baleen whales, Minke Whales feed on krill and small fish. The mouths of Minke Whales contain bristle like structures made of keratin that trap and filter food when the whale takes water into its mouth.
They migrate seasonally: Northern whales head north inspring, while Southern whales head further south. During the fall and winter months, both species head toward warmer tropical waters.
The chief predator of the Minke Whale is the Killer Whale. While larger whales may prove too formidable for Killer Whales at times, Minke Whales are just the right size to make a meal for a pod of Orcas. Unlike other larger whale species which can fight back using powerful swings from their tails, Minke Whales attempt to flee when pursued by these predators.
Minke Whales carry their babies for 10 months, and the calves measure nearly 10 feet long at birth! Newborns will nurse with their mother for 5 to 10 months. Breeding usually takes place during the summer.
Once thought to be a single species, it is now known that there are two separate species and several subspecies of Minke whale. All have similar characteristics. They grow up to about 35 feet in length, and can weigh as much as 10 tons. The body of the Minke Whale is streamlined and typical of a rorqual baleen whale, a group which includes the Minke’s relatives the Sei Whale and Blue Whale.
Minke Whales are dark in coloration, usually dark gray or black above which fades to white on their underside, often with some gray patterns and markings on their sides. Northern Minke Whales also have a distinctive white band on each flipper, while Southern Minke Whales lack this feature.
The odd name “Minke Whale” comes from the Norwegian word for the whale, “minkehval”. It is believed that the name originally came from a whaler named Meincke, who incorrectly identified a group of whales as BlueWhales, when they were actually Minkes.
Minkes have been historically hunted by whalers, though theywere long avoided due to their small size making them less appealing. However, after populations of larger whales were heavily reduced thanks to overhunting, the Minke became a more desirable target of hunters.
A global moratorium on whaling in 1986 helped prevent further overhunting of Minke Whales, although Norway, Iceland and Japan have continued to hunt Minkes in the years since.
The Common (Northern) Minke Whale is a species of “Least Concern”, while the Antarctic (Southern) Minke is “Near Threatened”. The prohibition of large scale whaling has helped these whales rebound, and although it is still considered near threatened, the Southern Minke’s population is still believed to be in the hundreds of thousands.
Minke Whales are popular animals for whale watching tourism. Their abundant numbers and curious nature toward humans make them appealing for whale watchers in Scotland and Iceland.
The Minke Whale is one of the few large whale species to have been kept in captivity for any length of time. This has only been attempted by the Mito Aquarium in Japan, and has not been particularly successful.
