Multicolored Reef, Tukangbesi Islands, Indonesia, 2005
Photograph by Tim Laman
Layers of coral, sea fans, crinoids, and sponges make up a healthy reef off Indonesia's Tukangbesi Islands. Lighted by a photographer's strobe, this scene would explode in brilliant colors, but in natural light, it looks altogether different. Scientists are studying how wavelengths of light change at depth and how fish perceive these colors.
