Family Astrocoeniidae

These coral have rough, solid skeletons pitted by tiny calices.  They inhabit areas exposed to surf, surge, or current.   Colony shape varies considerably according to physical factors and can be difficult to identify in some situations.  The Cauliflower coral group is taxonomically confused and in need of review.
