Their black-and-white plumage is often likened to a white tie suit. Some writers and artists have penguins based at the North Pole, but there are no wild penguins in the Arctic.

[94] [95] Considered a flagship species, 55 individuals were counted in captivity in North American zoos and aquaria in 1999. [96]
Of the Arctic lakes, they include glacial lakes and permafrost lakes. The polar regions include the Arctic Ocean and the Southern Ocean. The Arctic Ocean covers 14,000,000 km 2 (5,400,000 sq mi). [13] In the spring the ice covers an area of 5,000,000–8,000,000 km 2 (1,900,000–3,100,000 sq mi) and in the winter it is twice that. In this area ...
