Current thinking is that there are 18 living species of penguins. They are divided in to 6 genera. The two largest (and most colorful) are the Emperor and King of the Genus Aptenodytes. Emperors are found in Antarctica with colonies the furthest from the usual touring sites and are thus less likely to be seen. King penguins are seen mainly in the Subantarctic Islands such as South Gorgia. Also in Antarctica are the brush tailed penguins, Genus Pygoscelis. These include Chinstraps, Gentoo and Adelie. The largest genus is Eudyptes- the crested penguins. Included are the Macaroni, Royal, the Northern and Southern Rockhoppers, Fiordland, Snares and Erect-crested. The next largest group are from Genus Spheniscus. They are known as the Banded penguins and include Magellanic, African, Humboldt and the Galapagos. The latter is unique in that it is the only penguin that can be seen north of the equator. The Genus Megadyptes contains only the Yellow Eyed penguin, found in Southern New Zealand and its sub antarctic islands. Last is the Little Penguin, Eudyptula minor. It is a bit of a trouble maker as it is also known as the Fairy Penguin and the Blue or Little Blue penguin. The International Ornithologists Union considers there to be 6 sub-species that are distributed from New Zealand through southern Australia.
