Question

How many species of penguins are there?

Answer 1

there are 17 species

Answer 2

There are currently 17 species of Penguins (some scientists divide them in 18 or even 19 species). Fossil records indicate that there used to be more in the past. The current ones, all living in the southern hemisphere, are: Adelie, African, Chinstrap, Emperor, Erect Crested, Fairy, Fjordland, Galapagos, Gentoo, Humboldt, King, Macaroni, Magellanic, Rockhopper, Royal, Snares Island and Yellow Eyed. Some have multiple names (royal=king, little blue=fairy...). The current species are divided into 6 genus: Aptenodytes, Eudyptes, Eudyptula, Megadyptes, Pygoscelis and Spheniscus. I know well only the Adelie and Emperor which lived in the vicinity of Dumont d'Urville, but I have a few pictures of the Fairy (aka Little Blue) and Yellow Eyed penguins on my Tasmanian and New Zealand pages.

Many more species of fossile penguins are known.
