Maze and Star Coral; Merulinidae family

Maze and Star Coral are so named because of the intricate maze like structure that some members of the family have on their surface. And some do look quite star like too… On scuba dives they are yet another underwater photographer’s macro delight.

Dipsastraea species

Mainly members of the defunct Favia family. Distinct in not having fused walls.

Favites species

These attractive hard corals are distinguished by having shared walls to their corallites - well, most of them anyway...

Hydnophora species

Unique because of the small hill-like structures on its surface, known as hydnophores.

Paragoniastrea australensis

Very similar to Platygyra lamellina and daedela - only easy to identify correctly in skeletal form, unfortunately.

Pectinia species

Quite a common hard coral around Koh Phangan. It's another so-called Cauliflower Coral, although we're not sure why!

Platygyra species

Classic maze coral - commonly seen on our coral reefs. Very difficult to tell apart from Paragoniastrea australensis.

Other Merulinidae family

Various Merulina species corals. Identifications often unsure, especially after the recent revision...
