General Characteristics

The common minke whale is the smallest species of the rorqual family, also called balaenopterid family. It is also the most common of all baleen whale species.

Average size

8-10 m long, 9 tonnes in the Northern Hemisphere. Females are larger.


Up to 60 years.


One calf probably every year from 7-8 years of age.


No regular north-south migration, but shifts in latitudinal abundance with season.


Lunge-gulping' on euphausiids and a variety of shoaling fish including herring, capelin and cod.

At sea

The body is relatively robust, especially compared to the other rorquals. The head is very acute in shape and the rostrum fairly flat, which gives the nickname "pikehead". The dorsal fin is relatively tall and falcate, located two-thirds back along the body.

Common minke whales are black or dark grey dorsally and white on the ventral side, with a pale chevron on the back behind the head extending down onto the flanks. A transverse white band on the flippers is characteristic for the species in the Northern Hemisphere. The blow is low, rising only to about 2–3m, very inconspicuous and rarely visible in the North Atlantic. Common minke whales do not raise their flukes when diving, although the back is well arched. Many of them are very inquisitive and can approach vessels. They can be quite fast swimmers.

From a distance, common minke whales can be confused with bottlenose whales (and some other beaked whales), but the latter have bulbous heads and defined beaks, while the common minke's head is sharply triangular. Also in the North Atlantic, common minke whales are usually solitary, while beaked whales appear generally in groups.

Males and females are very similar in their general appearance, but females are somewhat larger than males. They attain a length of 8–9 m and a weight of about 8 tonnes in the North Atlantic, while they are slightly larger in the southern hemisphere.


The very characteristic head is the extremely narrow, pointed and triangular rostrum, with a single prominent head ridge. The tail flukes are broad, with a median notch. The flippers are slim and pointed.

As a rorqual, the common minke whale bears 50 to 70 ventral grooves along the ventral side of the body, running from the underside of the lower jaw to just beyond the flippers, ending anterior to the navel.

As a baleen whale, the common minke whale has a series of 230–360 baleen plates hanging on each side of the upper jaw, which measure up to 30 cm in length and 12 cm in width at the base. The plates are mostly yellowish white, with fine, white bristles.
