Overview

Comprehensive Description

Description

 Adult corals either encrusting and polystomatous or free-living and monostomatous (Gittenberger et al. 2011, Benzoni et al. 2012). Outline of free-living, unfragmented specimens varying from circular to oval. Juveniles may be hexagonal. Free-living corals may fracture repeatedly into regenerating wedge-shaped pieces (Hoeksema 1989, Yamashiro et al. 1989, Yamashiro and Nishihira 1994, 1998, Hoeksema and Waheed 2011, 2012). Fragmenting corals may produce extra stomata along fracture lines. Corallum wall without perforations. Septal margins ornamented by fine, sharp dentations. Costae covered by fine spiny protuberances, which may become granular and blunt in large specimens. Tentacles small and usually translucent in extended state.

Physical Description

Diagnostic Description

Description

Corals are solitary, free-living, flat or dome-shaped, circular or slightly oval in outline, with a central mouth. Septa have fine teeth, costae are fine, without undersurface pits. Polyps are usually extended only at night. Fine tentacles cover the upper surface of the disc. (Veron, 1986 <57>)

Cycloseris

Cycloseris is a genus of solitary disc corals in the family Fungiidae. They are found in the Indo-Pacific. They inhabit the lower reef slopes, and the areas between reefs with soft sediments. They tolerate turbid waters.[2]

Description

Corals in the genus Cycloseris are mostly solitary and free living, some attaining 10 centimetres (3.9 in) in diameter. The discs are either round or oval and the central mouth, which is surrounded by tentacles, may be a slit. The polyp sits in a calcareous cup, the corallite, and only extends its tentacles to feed at night. The septae are vertical skeletal elements inside the corallite wall and the costae unite the septae at the base. In the genus Cycloseris, both are thick but have fine teeth and are characteristic of the different species. Cycloseris can be confused with specimens of the related genus Fungia but the former are always free living, even as juveniles, while the latter bear a scar showing where they were attached when young.[2]

Species

The World Register of Marine Species currently lists the following species:[1]
