Coral Biota

An area dominated by coral, a colonial marine Cnidarian from the Order Scleractinia, Antipatharia, Alcyonacea or Pennatulacea, where colonies are composed of individual polyps that are connected by living tissue. In some, corals polyps excrete an exoskeleton and are embedded within this structure, while others possess large amounts of gelatinous tissue and are much softer.
