Found in the Indo-Pacific.
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.
The Coral Finder lists Cycloseris in one key group with Fungia being a candidate for confusion.

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.
