Common minke whale involved groups of four and five whales. Northern minke whales occasionally breach, sometimes completely clearing the water – one individual in the Johnstone Strait area reacted to the approach of foraging killer whales by breaching eight times in rapid succession. All of the dwarf minke whales caught off South Africa were taken singly. The majority of sightings of dwarf minke whales on the Great Barrier Reef involved either single whales (53.3%) or pairs (28.9%), with the maximum number of individuals in a group being eight. Four cow-calf pairs were seen as well. Individuals encountered on the various reef systems there

Antarctic minkes lack the bright white, transverse "flipper band" of the common minke and the white "shoulder blaze" and bright white "flipper patch" (occupying the proximal two-thirds of the flipper) of the dwarf minke. Instead, their narrow, pointed flippers, about one-sixth to one-eighth of the total body length, are normally either a plain light gray with an almost white leading edge and a darker gray trailing edge or two-toned, with a thin
