Cool dip on a warm day

The African Penguin (Spheniscus demersus) is also known as the Blackfooted Penguin (and formerly as the Jackass Penguin).


They have a black stripe and black spots on the chest, the spots being unique for every penguin, like human fingerprints. They have pink sweat glands above their eyes. The hotter the penguin gets, the more blood is sent to these sweat glands so it may be cooled by the surrounding air, thus making the glands more pink.
