Minke Whale
Balaenoptera physalus

 
 

Juvenile minke whale

Length:  20-30 feet
Weight: 6-8 tons
Status: common

The minke’s Latin name means “baleen whale with a pointed snout".  Legend has it that the Minke got its name from a Norwegian whaler whose last name was Meinke. The story goes that this whaler used to exaggerate the size of the whales he caught, and the other whalers referred to these small whales as “Meinke’s whales”. This name changed to Minke over time.

Minkes are still being hunted for their meat in certain countries such as Norway, Iceland and Japan

Coloration: Minkes are dark gray on their dorsal (top) side, and have white bands on their flippers known as “Minke Mittens”. (Minkes in the Southern Hemisphere lack these bands.) Minkes also have a small “blaze” on their back behind the blowhole, similar to that of a fin whale’s chevron. This blaze is used by some researchers to identify individual minkes in the field.

Feeding: Minkes have 200-300 baleen plates (made of keratin) on each side of their upper jaw. They use this filtering system to feed on schooling fish (such as herring and anchovies) and plankton.

Migration: The migration patterns of minkes are not well known. It is believed that some individuals may stay in the Gulf of Maine throughout the year, possibly moving farther south in the winter.

Mating/Calving: Gestation for minkes is about 10-11 months. The calf nurses for about 7 months. Most minkes in the southern Gulf of Maine are believed to be juvenile whales because they are rarely seen with calves.

 Whale watching: Minkes surface quickly - look for a dark back and tall dorsal fin.  They normally dive for 3-8 minutes, but have the ability to dive for up to 20 minutes.  Minkes do occasionally breach out of the water!

Population Status: Approximately 500,000 to 1 million worldwide. Minkes are not endangered and are, in fact, one of the most abundant whale species.
