The male and female are similar in plumage and size, reaching 122cm (48in) in height and weighing from 22 to 45kg (49 to 99lb). The dorsal side  and head are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Like all penguins it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat.
