Hard coral Family Faviidae A hard coral is actually a colony of small to tiny polyps. The polyps look like sea anemones, with a ring of tentacles surrounding a central mouth. The polyps produce a hard skeleton and the entire hard coral is made up of the joined up skeletons of countless small polyps. At low tide, you may still see the extened polyps on the portions of the coral that remains submerged in water.
