Distinctive marks of these penguins are the white ring surrounding the eye and the feathers at the base of the bill. These long feathers hide most of the red bill. The tail is a little longer than other penguins' tails.
Adélie Penguins are excellent swimmers and can dive to depths of up to 175 metres in search of prey.
The Adélie Penguin is named after Adéle d’Urville, the wife of the French Antarctic explorer Dumont d’Urville.
