An image of Scolymia australis species coral in UV light. This species of coral will grow 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.
