Wikipedia Abstract

The African penguin (Spheniscus demersus), also known as the jackass penguin and black-footed penguin is a species of penguin, confined to southern African waters. It is also widely known as the "jackass" penguin for its donkey-like bray, although several related species of South American penguins produce the same sound. Like all extant penguins it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Adults weigh on average 2.2–3.5 kg (4.9–7.7 lb) and are 60–70 cm (24–28 in) tall.
