The two polyps thus created then generate their missing body parts and exoskeleton. Transversal division occurs when polyps and the exoskeleton divide transversally into two parts. This means one has the basal disc (bottom) and the other has the oral disc (top); the new polyps must separately generate the missing pieces.
The polyps of stony corals have six-fold symmetry while those of soft corals have eight. The mouth of each polyp is surrounded by a ring of tentacles. In stony corals these are cylindrical and taper to a point, but in soft corals they are pinnate with side branches known as pinnules. In some tropical species these are reduced to mere stubs and in some they are fused to give a paddle-like appearance.

[10] In most corals, the tentacles are retracted by day and spread aqui out at night to catch plankton and other small organisms. Shallow water species of both stony and mais soft corals can be zooxanthellate, the corals supplementing their plankton diet with the products of photosynthesis produced by these fonte symbionts.[oito] The polyps interconnect by a complex and well-developed system of gastrovascular canals, allowing significant sharing of nutrients and symbionts.[11]
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. Corals species include the mais important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
