Distinguished by a bright red orange bill and white eye patches, the Emperor penguin (Aptenodytes forsteri) is the largest of 17 penguin species, the deepest diver of any bird, and the only animal to winter on Antarctica’s open ice. The coin’s reverse depicts a coloured image Emperor penguins and two chicks standing on icefloes, which appears within the outline of Antarctica. As well as the inscription 2012: EMPEROR PENGUIN, the reverse includes the words ‘Australian Antarctic Territory’, and the Perth Mint’s traditional ‘P’ mintmark.
