Brain coral is a common name given to various corals in the families Mussidae and Merulinidae, so called due to their generally spheroid shape and grooved surface which resembles a brain. Each head of coral is formed by a colony of genetically identical polyps which secrete a hard skeleton of calcium carbonate; this makes them important coral ...

Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are colonial.
Mussids are hermatypic or reef-building corals and can be either solitary or colonial. They are generally massive corals with robust, dense skeletons. The corallites (stony cups secreted by the polyps in which they sit) are large, with the septa (stony ridges) decorated by long teeth. The polyps are large and fleshy, and in certain species, the ...
