Minke whale points to evidence that the minke whale has fat deposits in their jaws intended for sound reception, much like Odontocetes. The brains of minke whales have around 12.8 billion neocortical neurons and 98.2 billion neocortical glia. The whale breathes three to five times at short intervals before 'deep-diving' for two to 20 minutes. Deep dives are preceded by a pronounced arching of the back. The maximum swimming speed of minkes has been estimated at . Both species undertake seasonal migration routes to the poles during spring and towards the tropics during fall and winter. Difference between the timing of the
Antarctic minke whale dark gray dorsally and clean white (occasionally light gray to gray) ventrally with a thin, dusky margin. Some small, dark gray "speckling" may be present on the body. 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
