Cycloseris (Fungiidae)

Welcome to the Cycloseris 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: Fungia.


Vital Statistics

  • 11 species
  • Coral Finder p. 24
  • COTW – Vol 2 p. 236-247

Distribution

Found in the Indo-Pacific.

ID Tips

Cycloseris are small, solitary and free-living, growing up to 10cm in diameter.  They are found on lower reef slopes, inter-reefal areas with soft sediments, and turbid waters.

The septa and costae are thick but with fine teeth, giving them a smooth look.  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 Cycloseris in one key group with Fungia being a candidate for confusion.

Similar genera to Cycloseris (Coral Finder p24)

Cycloseris can be confused with small Fungia, but may be easily separated by examining the underside of the colony. Cycloseris is free-living throughout its life, whereas juvenile Fungia are attached, but become free-living with age.  If the individual is attached, it must be Fungia, if it is free-living check for the attachment scar characteristic of Fungia. In addition, Cycloseris forms round solitary corallites, whereas Fungia may be more elongate in shape.
