Sea fan coral. Coloured composite X-ray of two seahorses above 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. These secretions 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. Seahorses are fish that inhabit reefs and reeds throughout the world's temperate and tropical seas. They grasp onto structures such as coral with their prehensile tails | |
