The Frog That Hides Its Blood
When a Fleischmann's glass frog sleeps on a leaf, its translucent belly becomes part of an extraordinary camouflage trick. Red blood cells normally make animal tissue look less transparent because they absorb light, but this frog can move about 89 percent of those cells out of circulation and pack them into the liver. With less red pigment moving through the body, the frog can become two to three times more transparent against the leaf beneath it. The result is not invisibility, but a precise biological hiding strategy: a green back blends with foliage while a clearer belly reduces the shadowy outline predators might notice.
