Honeycomb Coral; Diploastreidae family

Honeycomb (Star, as was) Coral was previously listed in the (now invalid) family Faviidae. Now it has been given its very own family, due to a number of unique features that it has been found to possess. We must take some underwater photos of Honeycomb Coral when night diving at Mae Haad Reef, to see how it looks when feeding.
