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.

If the stressful conditions persist, the polyp eventually dies.[23] Zooxanthellae are located within the coral cytoplasm and due to the algae's photosynthetic activity the internal pH of the coral can be raised; this behavior indicates that the zooxanthellae are responsible to some extent for the metabolism of their host corals [24] aqui Reproduction[edit]
Tabulate corals occur in limestones and calcareous shales of the Ordovician and Silurian periods, and often form low cushions or branching masses of calcite alongside rugose corals.
Increasing sea temperatures in tropical regions (~1 degree C) the last century have caused major coral mais info bleaching, aqui death, and therefore shrinking coral populations since although they are able to adapt and acclimate, it is uncertain if this evolutionary process will happen quickly enough to prevent major reduction of their numbers.[77]

Some soft corals encrust other sea objects or form lobes. Others are tree-like or whip-like and chem a fonte central axial skeleton embedded at its base in the matrix of the supporting branch.[9] These branches are composed either of a fibrous protein called gorgonin or of a calcified material.

Presently, corals are classified as certain species of animals within the sub-classes Hexacorallia and Octocorallia of the class Anthozoa in the phylum Cnidaria.[seis] Hexacorallia includes the stony corals and these groups have polyps that generally have a 6-fold symmetry.
