A) Symmetry of corallites of the Tabulata. The bases of corallites have a conical and auloporoidshape, respectively, rounded and elliptical cross-sectional shapes. In the first case, …Coral is secreted by some coral forming actinozoa. The skeleton of a solitary polyp is known as the corallite (Fig. 12.38) and many corallites combine to form the skeletal mass. The skeleton as a whole is known as the corallum. The structure of a corallum will be clear from the detailed structural organisa­tion of a single corallite. A corallite is the skeletal cup, formed by an individual stony coral polyp, in which the polyp sits and into which it can retract. The cup is composed of aragonite, a crystalline form of calcium carbonate, and is secreted by the polyp. Corallites vary in size, but in most colonial corals they are less than 3 mm (0.12 in) in diameter. [1]Characters: Colonies are sturdy fused branches with rounded tips.
