Very Cool Heat Map Of Penguins

As if their home in Antarctica weren’t cold enough, emperor penguins actually allow their exteriors to drop at least 7°F below their surroundings. The change helps the penguins stay warm, a recent paper showed. When the outer layer of feathers radiates heat to the sky, it becomes colder than its immediate environment, so heat flows back in. The cycle keeps the temperature underneath the plumage constant—and the penguin alive.  Check out this very cool looking heat map of Emperor Penguins. psc1213_hl_111b
