Soft coral
The stony coral (Scleractinia)….(1)
Corallum entire skeleton of a scleractinian coral, regardless of , gwhether the animal is solitary or colonial
Corallite the skeleton of a single polypCalyx concave depression that houses the polyp (pl: calices)Theca outer wall of the coralliteSeptum skeletal plates that radiate into the calyx from the wall (sometimes called scleroseptum); which project inward and support the mesenteries of the polyp (pl: septa)p yp (p p )
Coenosteum skeletal material between walls of adjacent corallites
Costa extensions of the septa outside the wall of the corallite (pl: costae)
The stony coral (Scleractinia)….(2)
Columella central structure of the calyx formed by fusion of the lower elements of the septap
Tuberculae larger-than-polyp bumps occurring in the coenosteumVerrucae larger-than-polyp bumps composed of several corallites
Papillae smaller-than-polyp, nipple-like bumps on the surface of the skeletonthe skeleton

The arrangement of corallite (3)
Cerioid apabila dinding koralit saling menyatu dan membentuk permukaan yang datarEx. Leptastrea purpurea
Plocoid tiap koralit memiliki Plocoid tiap koralit memiliki dindingnya masing-masing yang terhubung oleh coenosteumEx.
The arrangement of corallite (4)
Dendroid koloni hampir menyerupai pohon yang dijumpai cabang-cabang dan di ujung cabang biasanya dijumpai calix utamaEx. Tubastrea micrantha
Meandroid koloni mempunyai koralitMeandroid koloni mempunyai koralityang membentuk lembah dan koralit disatukan oleh dinding-dinding yang saling menyatu dan membentuk alur-alur seperti sungaiEx. Pavona varians
The arrangement of corallite (5)
Hydnophorid koralit terbentuk seperti bukit tersebar pada seluruh permukaan sehingga sangat mudah untuk dikenalEx. Hydnophora rigiday p g
Flabello Meandroid seperti Flabello-Meandroid seperti meandroid, membentuk lembah-lembah memanjang, namun koralit tidak memiliki dinding bersamaEx. Symphillia
