Animal Species:Stony Coral
Few stony corals grow around Sydney but of these, Plesiastrea versipora is most often noticed by divers.
This stony coral is usually a vivid green, or sometimes brown, colour with large circular pits in which the coral polyps live. The colouration is due to symbiotic algae, called zooxanthellae, living in the coral tissue. The algae photosynthesise, converting sunlight into energy that can be used by the coral.
Indo-Pacific region and southern parts of Australia.
Stony corals live in coastal waters.
