Iridescence as Camouflage (VIDEO) Cell Press This video is under embargo. Please login to access this video.

They further show that the effects of this protective function are further enhanced by glossy backgrounds. This newly discovered function may explain the widespread occurrence of iridescence in many animals. Credit University of Bristol / Kjernsmo et al. Usage Restrictions Credit Required.
