Sea urchins, parrot fish, molluscs (like limpets and chitons) feed on coralline algae and they provide microhabitats which offer protection to many young animals including sea urchins, chitons, and limpets.
Most corals, like other cnidarians, contain a symbiotic algae called zooxanthellae, within their gastrodermal cells. The coral provides the algae with a protected environment and the compounds necessary for photosynthesis. second feature all corals possess is a circle of tentacles, extensions of the body wall that surround the mouth. Tentacles help the coral to capture and ingest plankton for food, clear away debris from the mouth, and act as the animals primary means of defense (Barnes, R.D., 1987; Levinton, 1995).
