Join Courtney to explore the world of biofluorescence in tree frogs! We're discovering that there is a hidden world of light that we don't see in many animals, on land and in the water. When higher energy wavelengths of light (e.g., ultra-violet or blue light) are absorbed, they are reemitted at lower energy wavelengths in living organisms, resulting in a glow with brilliant fluorescent colors including blues, greens, and red!
