Heliofungia


Under construction

Heliofungia (Fungiidae)

Welcome to the Heliofungia 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: Euphyllia.

Just a quick glance at the growing number of aquarium sites highlights that Heliofungia is a very popular coral in the aquarium trade.  Despite this popularity, it is only in recent years that research has been started into understanding this genus and its population dynamics.  There is still much to learn but Knittweis et al., (2009) in the suggested reading list below provide great information on one of the most up to date studies.

Vital Statistics

  • 1 species
  • Coral Finder p. 24, 27
  • COTW – Vol 2 p. 254-255

Distribution

Found in the Indo-Pacific

ID Tips

Juvenile Heliofungia are attached, but become free-living as they grow.  The solitary corallites are large circular to oval discs, but may be hidden by long anemone-like tentacles during the day.

The septa have fine lobed teeth that clearly run out from the large central mouth (30mm wide).  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 Heliofungia in two key groups with Euphyllia being a candidate for confusion.  Note that the long tentacles may look like an anemone.  By wafting your hand over the surface of the colony, the hard disc like skeleton may be seen.

Similar genera to Heliofungia (Coral Finder p27)

Heliofungia may look superficially like Euphyllia but can be easily separated by the larger tentacles and the disc-like skeleton characteristic of HeliofungiaEuphyllia has a meandering skeleton with separate walls that may be seen by wafting your hand over the colony causing the tentacles to retract.
