African Penguin

The African Penguin (Spheniscus demersus), also known as the 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 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. It has distinctive pink patches of skin above the eyes and a black facial mask; the body upperparts are black and sharply delineated from the white underparts, which are spotted and marked with a black band. This pink gland above their eyes helps them to cope with changing climates. When the temperature gets hotter, the body of the African Penguin sends more blood to these glands to be cooled by the air surrounding it. This then causes the gland to turn a darker shade of pink.
