Adélie Penguins (Pygoscelis Adeliae): The Adélie penguin can be found forming colonies on islands, beaches and headlands all around the Antarctic coast. Adélie penguins are used by scientists as an indicator species to monitor the abundance of krill, so important to the web of Antarctic life. With its white front and the white ring around its eyes, the penguin has a handsome, yet comical appearance. Its beak is reddish with a black tip.
