Herpolitha


Under construction

Herpolitha (Fungiidae)

Welcome to the Herpolitha 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. Then click on the following link for further comparison with a similar genus: Ctenactis.

Vital Statistics

  • 2 species
  • Coral Finder p. 25
  • COTW – Vol 2 p. 291-293

Distribution

Found in the Indo-Pacific.

ID Tips

Herpolitha form free-living, elongate colonies.  The colonies are domed in the centre, where a thin slit-like furrow containing a number of mouths may be seen.  Further secondary mouths are scattered over the colony.  Herpolitha is generally found in shallow reef zones.

The septa have large saw-like teeth, and are disjointed so they do not run continuously all the way to the colony edge. The arrangement of septa running down the upper surface and costae running along the lower surface are characteristic of the Fungiidae.  Check out the Fungiidae training video for more information.

Similar Genera

The Coral Finder lists Herpolitha in one key group with Ctenactis being a candidate for confusion.

Similar genera to Herpolitha (Coral Finder p24-25)

Herpolitha can be confused with Ctenactis, but may be easily separated by the colonial nature of Herpolitha; secondary mouths may be seen across the colony surface.  Ctenactis may have more than one mouth, but they are found in the axial-furrow.  The septal teeth of Herpolitha are also smaller than those of Ctenactis.
