Sea fan coral. Coloured X-ray of a sea fan,or gorgonian. Sea fans are coral-like organisms that live in a large colony. Each organism,or polyp,secretes a hard mineral around itself for protection and support. The secretions of the entire colony form the rocky skeleton seen here. Sea fan polyps feed by sifting minute plankton particles from the water. Sea fans are flat,and are orientated to present the maximum surface area to the prevailing current | |
