Emperors are the largest of all penguins—an average bird stands some 45 inches (115 centimetres) tall. These flightless animals live on the Antarctic ice and in the frigid surrounding waters.
Penguins employ physiological adaptations and cooperative behaviors in order to deal with an incredibly harsh environment, where wind chills can reach -76°F (-60°C).They huddle together to escape wind and conserve warmth. Individuals take turns moving to the group's protected and relatively toasty interior. Once a penguin has warmed a bit it will move to the perimeter of the group so that others can enjoy protection from the icy elements.
