Diploastrea (Faviidae)

Welcome to the Diploastrea genus landing page. In this section, you will find general information about this genus and tips on how to identify it. If you are looking to confirm an observation made with the Coral Finder, use the image browser below to verify what you saw underwater.  The nature of this genus is highly distinctive, which means that it is unlikely to confuse it with other members of the group.

Diploastrea provides a welcome relief when identifying members of the Faviidae family.  It contains one species, which is morphologically similar across the Indo-Pacific.  Sit back, relax and enjoy this coral because when you have seen it in the field just the once, you will be confident with its identification

Vital Statistics

  • 1 species
  • Coral Finder p. 11
  • COTW – Vol 3 p.230-231

Distribution

Locally common in the Indo-Pacific.

ID Tips

Diploastrea forms mound colonies that may grow into massive shield-like structures covered in neat, uniform corallites.  Overall colony colour is generally a dull grey-brown to green.

The corallites are large (8-10mm) low polygonal cones.  The septa form distinct radiating ridges that start at the columella and run down the sides of the thick walls.

Similar Genera

The Coral Finder lists Diploastrea within one key group with other members of the Faviidae family.  Diploastrea’s distinctive corallites make it easy to differentiate from these corals.
