Leaf-Tailed Geckos Look Like Dead Leaves

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.

Their fur turns white in winter and brown in summer, matching the landscape in each season.

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