Antarctic Adélie Penguins

Antarctic Adélie Penguins

Adélie penguins are the most common birds in the Antarctic. Living in colonies with populations that can total over 100,000, they have many adaptations that enable them to survive and thrive in the harsh Antarctic environment. These adaptations include strong toenails to help them climb rocks and propel themselves forward on the ice; a tail that supports their bodies when upright and helps to steer when they swim in the water; and a hydrodynamic body and short, stiff flippers for smooth, fast swimming.
