  Scleractinia
The Scleractinia (scler = hard, actinia = ray), or stony star corals, are polyp animals that are found exclusively in marine habitats.
The most recent taxonomic revision of the Scleractinia (Veron, 1995, 2000) divides the order into 13 suborders of which 7 have living representatives.
Nine of these suborders were present in the Mid-Triassic (240 million years ago) when the Scleractinia first appear in the fossil record.

 Zoantharia
An alternative hypothesis for the relationship of Scleractinia to the extant, non-skeletalized zoantharians is that the soft-bodied groups are derived from scleractinians by the loss of the skeleton.
Buddemeier and Fautin (1996) estimated from this analysis that actiniarian and scleractinian/corallimorpharian lineages diverged 75 mya, and the corallimorpharian lineage diverged from the scleractinian lineage 55 mya.
Scleractinia and Actiniaria is each monophyletic; Corallimorpharia is not monophyletic and, although it is most closely related to Scleractinia, its relative placement - basal to or within Scleractinia -- is unresolved.

The overall averages for major parameters were: relief 16 cm, sediment depth 6 cm, sand cover 32%, macroalgae cover 25%, scleractinia density 1.3 square m.
Scleractinia density was surprisingly high for this turbid nearshore habitat.
This suggests the habitat was chronically disturbed with respect to Scleractinia recruitment in the last decade.

-The Scleractinia, which are one of the most important builders of modern reefs, have been considered to have first appeared in the Middle Triassic.
The Paleozoic scleractinians evolved within the framework of their basic body plan and a direct derivation of the Scleractinia from the Rugosa is not probable.
Other examples of Paleozoic Scleractinia and scleractiniamorphs will be found, probably in shallow-water reefal facies or deeper-water communities, bridging the stratigraphic gaps in occurrence and elucidating the origin of the Scleractinia and their body plan.

The development of scleractinia is a distinguishing factor of this sub-class.

Microstructural differences observable within septa are currently recognized as major phylogenetic criteria among Scleractinia.
This, however, may result from the numerous uncertainties concerning the microstructural pattern of species upon which major taxa are based.

Both tabulate and rugose corals disappeared in the Permo-Triassic mass extinction about 245 million years ago.
In the middle Triassic, a new clade of corals appeared, the Scleractinia.
The Scleractinia do not appear to be close relatives of either the Tabulata or the Rugosa, and probably evolved from sea anemone-like ancestors that have not been preserved as fossils.

The combination of an axial corallite with radially arrayed secondary corallites has been regarded as one of the morphological and ecological pinnacles of coral evolution, yet it is rare among the Scleractinia.
This growth form has not been recognized in any Cenozoic dendrophylliids.
