Antarctic minke whale is possible between hybrids of the two species. The Antarctic minke is among the smallest of the baleen whales, with only the common minke and the pygmy right whale being smaller. The longest caught off Brazil were an female taken in 1969 and an male taken in 1975, the former four feet longer than the second longest females and the latter five feet longer than the second longest males. Off South Africa, the longest measured were a female and a male. The heaviest caught in the Antarctic were a female that weighed 10.4 metric tons (11.5 short tons) and an
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
