Australogyra (Faviidae)

Welcome to the Australogyra 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 identify a genus similar to what you saw underwater. Then choose one of the following links for further comparison with similar genera: Paraclavarina, or Hydnophora.

Vital Statistics

  • 1 species
  • Coral Finder p. 5
  • COTW – Vol 3 p.194


Uncommon in the Indo-Pacific.

ID Tips

Australogyra forms branching thickets or smaller branched colonies.

The corallites are meandering forming short valleys with thick smooth walls that are wrapped around the branching growth form.  The result is an overall distinctive sculpted appearance.

The thick septa are characteristic of the Faviidae family.

Similar Genera

The Coral Finder lists Australogyra in one key group with Paraclavarina and Hydnophora, being possible candidates for confusion.

Similar genera to Australogyra (Coral Finder p8)

Australogyra can be confused with Paraclavarina but are easily separated by the deeper valleys and thicker walls typical of Australogyra. The branches of Paraclavarina have a more faceted look and a triangular cross-section. Hydnophora forms similar branching growth forms but can be clearly distinguished by its skeletal bumps, or ‘monticules’.  Australogyra doesn’t have any similar bumps.


Similar genus: Paraclavarina

Similar genus: Hydnophora
