These flightless seabirds are found in the Southern Hemisphere. They have dark upperparts with a mainly white breast and flipper-like wings for swimming. There are 11 known species in Antarctica, the largest of which is the Emperor, around 120cm tall. Penguins are fairly widely distributed, forming breeding colonies, varying from year to year, from 10,000 to a few hundred pairs. Fortunately there are no land-based predatory animals in Antarctica, no polar bears or ice foxes. As a result Penguins are not afraid of humans and one can get close to a colony.
