Sometimes considered as rocks, stony corals may easily be overlooked.
Through this photography, I would like to show that despite their hard exoskeleton, corals are in fact composed of thousands of individual living polyps. The polyps contain microscopic algae, called zooxanthellae, with which they live in symbiosis; that is both organisms benefit from each other in the relationship.
Moreover, the pattern created by the groups of polyps makes you wonder how great is the artist who did it.
