于阿特兰大格鲁吉亚水族馆的黑脚企鹅。

黑脚企鹅(学名:Spheniscus demersus),又名非洲企鹅斑嘴环企鹅公驴企鹅,是生活在非洲西南岸的企鹅,在纳米比亚至南非近伊莉莎白港的阿尔哥亚湾的24个岛上都有群族,最大的位于戴尔岛。于1980年代,可能由于掠食者的减少,黑脚企鹅群族扩展至近开普敦的博尔德斯海滩及贝蒂湾。另一个大陆群族是在纳米比亚,但出现的时间则不明。由于在博尔德斯海滩的黑脚企鹅容许游人的接近,所以当地吸引了很多游客到来。

黑脚企鹅的近亲是在南美洲南部的汉波德企鹅及麦哲伦企鹅及近赤道太平洋的加拉帕戈斯企鹅。

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. 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.
