Emperor penguins keep warm at sub-zero Arctic temperatures. How do they do it? Think of the energy generated during a sporting event wave of the crowd, and you will be getting warmer! This short clip shows that tiny, wave-like movement and shuffling allows each penguin to eventually end up in the center of the huddle where temperatures can reach more than 90 degrees Fahrenheit! Use this within your own presentation to show how similar patterns exist in nature or how behavioral adaptations help species to survive surprising conditions.
