Megadyptes antipodes is a tall and slender penguin. It stands just over 60 cm and weighs five to eight kilograms. Its distinct features are its yellow eyes and yellow feathers that encircle the head. The rest of the animal is black and white. Males and females look similar but males often have a larger head and feet. Megadyptes antipodes only varies in appearance during the molting season, when feathers are being replaced. Juveniles have gray and not yellow eyes; the yellow feathers are usually absent or muted also. The rest of the body is a downy gray or dark brown. Megadyptes antipodes is the fourth largest penguin in the world
(Vernon 1991; Houston 1998; Yellow Eyed Penguin Trust 1998).
