Description
The African penguin (Spheniscus demersus), also known as the Cape penguin, and South African penguin, is a species of penguin confined to southern African waters. 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. 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. The pink gland above their eyes helps them to cope with changing temperatures. 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.
The African penguin is a pursuit diver and feeds primarily on fish and squid. Once extremely numerous, the African penguin is declining rapidly due to a combination of several threats and is classified as endangered. It is a charismatic species and is popular with tourists. Other vernacular names of the species include black-footed penguin and jackass penguin, which it is called due to its loud donkey-like bray, although several related species of South American penguins produce the same sound.
Penguins are classified as birds (Aves) in zoological terms. They are black and white flightless seabirds of the family Spheniscidae which are found in the southern hemisphere, chiefly in the Antarctic (although several species live in more temperate regions).
