(A polyp is a can-like body with a single opening leading to the stomach, surrounded by a ring of tentacles.) Each polyp makes a small wasted cup, called a calyx, which it hides in when inactive or threatened. As the coral villa ge grows it must secrete new skeletal tangible on top of the old. Years upon years later the accretion of skeletal material forms a coral reef. What are the conditions needed for the addition of coral? Coral reefs can survive in nearly both depth of water.

They can be institute as orphic as 19,700 feet or right at the waters surface, even sticky above water. Corals which build reefs however, must abide at depths of slight than 150 feet because corals need sunlight to photosynthesize in order to come food to eat. Corals grow faster in clean and illume water. This healthy water allows light to distort th e algae living in the coral polyps tissue.
