Arctic Foxes and Snowshoe Hares Change Coat Color With the Seasons

With thousands of species, some stick insects rock back and forth as if moved by the wind.

These flatfish adjust their pattern and color within moments, and can blend in on sand and gravel.

Madagascar's Uroplatus geckos have flattened bodies and ragged edges that make them nearly invisible against bark and leaf litter.

Rather than only blending in, chameleons shift color to signal mood, attract mates and regulate temperature.
