Family Poritidae

Lobe & Finger Corals

Massive or branching species easily recognized by their small hexagonal calices with a snowflake pattern.  Many are difficult to identify in the field since ID's are based upon minute skeletal structures hidden by the live polyp.  Lobe and Finger coral are dominant reef-forming species in Hawaii while the others are occasional in clear waters.

Large fleshy polyp species of tropical seas include Alveopora and Goniopora with 12 and 24 tentacles.  These do not occur in Hawaii or the Atlantic.

All coral skeletons illustrated are from scientific collections taken prior to 1998.
