Goby and Bubble Coral, Indonesia, 2005
Photograph by Tim Laman
A goby fish with brilliant orange streaks stands out on a bit of gray bubble coral in Maumere Bay off Indonesia's Flores Island. In most of the ocean, turbid or murky waters force creatures to use nonvisual means of communication—smell, taste, touch, and sound. But in the clear, sunlit waters of coral reefs, light abounds, vision predominates, and animals drape themselves in blazing color.
