This species is a non colonial stony coral. Calcareous skeleton: reaching exceptionally 0.80 cm vertically. Diameter of the polyps: 0.7 cm to the maximum, often much less. Round section; chalice somewhat narrowed at the base. Bodies and oral disc: yellow or oranges sharp, the tentacles white; translucidus and constellated with yellow punctuations which correspond to the clusters of cnidocytes (Ref. 358).
Calcareous skeleton: reaching exceptionally 0.80 cm vertically. Diameter of the polyps: 0.7 cm to the maximum, often much less. Depth: present beyond 10 m, seldom less, and until the greatest depths (Ref. 358). Habitat: Underwater caves and anfractuosities, zones of solid drop shadow by rock overhangs, deep rock faces or not exposed with sunlight species present beyond 10 m, seldom less, and until the greatest depths (Ref. 358). Known from infra- and circalittoral zones (Ref. 85338). Biology: the chalice and the periphery of the oral disc are regularly colonized by the barnacles of the corals (Pyrgoma anglicum), species joining only the corals. Association: symphorism, or colonization is a symphorism; or durable colonization by an organization of the surface of another organization. The yellow coral does not suffer any injury; the barnacles seek doubtless protection that the tentacles irritant of the corals offer to them. It is not rare that the wall of the skeleton of the barnacles is covered by the tissues with the coral: one then any more does not distinguish on the chalice from the madrÃ©poraire that one small ball bored from an opening in his end (Ref. 358). Members of the class Anthozoa are either gonochoric or hermaphroditic. Mature gametes are shed into the coelenteron and spawned through the mouth. Life cycle: The zygote develops into a planktonic planula larva. Metamorphosis begins with early morphogenesis of tentacles, septa and pharynx before larval settlement on the aboral end (Ref. 833).
