Antarctic minke whale involve Type A killer whales, but on one occasion, in January 2009, a group of ten Type B or pack ice killer whales, which normally preyed on Weddell seals in the area by wave-washing them off ice floes, were observed to attack, kill, and feed on a juvenile Antarctic minke whale in Laubeuf Fjord, between Adelaide Island and the Antarctic Peninsula. Little has been published on the parasitic and epibiotic fauna of Antarctic minke whales. Individuals were often found with orange-brown to yellowish patches of the diatom "Cocconeis ceticola" on their bodies – 35.7% off South Africa and 67.5% in
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
