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.
The crown-of-thorns starfish (frequently abbreviated to COTS), [1] Acanthaster planci, is a large starfish that preys upon hard, or stony, coral polyps (Scleractinia). The crown-of-thorns starfish receives its name from venomous thornlike spines that cover its upper surface, resembling the biblical crown of thorns. It is one of the largest ...

Tubastraea coccinea was first documented in 1943 on Caribbean reefs in Curaçao and Puerto Rico. [3] T. coccinea is an invasive species that was documented to have spread as far north as the Florida Keys National Marine Sanctuary in 2004.
Consequently, the term "gorgonian coral" is commonly handed to multiple species in the order Alcyonacea that produce a mineralized skeletal axis (or axial-like layer) composed of calcite and the proteinaceous material gorgonin only and corresponds to only one of several families within the formally accepted taxon Gorgoniidae (Scleractinia).
Corallimorpharia is an order of marine cnidarians closely related to stony or reef building corals (Scleractinia). They occur in both temperate and tropical climates, although they are mostly tropical. Temperate forms tend to be very robust, with wide and long columns, whereas tropical forms tend to have very short columns with a wide oral disc ...
Although previously assigned to Faviidae, Budd et al. (2012) assigned it to Scleractinia incertae sedis based on phylogenetic results demonstrating the polyphyly of Faviidae. [1] Assigned to family Leptastreidae by Rowlett (2020). [2]
Rhizangiidae is a family of stony corals in the order Scleractinia. This family is closely related to Oculinidae. Members of this family are non-reef building corals and reproduce from stolons. The corallites are small and the septa are simple. [1]
