Fluorescent Coral in Long wave UV
An image of Pectinia species coral in Long wave UV Light showing green Fluorescence. This species of coral will glow brightly when illuminated in ultra-violet(UV) light. Each head of coral is formed by a colony of genetically identical polyps which secrete a hard skeleton of calcium carbonate; this makes them important coral reef builders. This image is part of a series showing the identical specimen in white light and UV light.
