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).
Octocorallia (also known as Alcyonaria) is a class of Anthozoa comprising over 3,000 species [1] of marine organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians (sea fans and sea whips) within three orders: Alcyonacea, Helioporacea, and Pennatulacea. [2]
Litophyton arboreum, also known as broccoli coral, is a common soft coral found from the Red Sea to the Western Pacific. It grows up to 80 cm, usually on seaward reef slopes or hard bottoms. The color of L. arboreum varies from pale olive-green to yellow or grey. L. arboreum are anthozoans in the order Alcyonacea in the family Nephtheidae.

Xeniidae is a family of soft coral in the order Alcyonacea. Predators. Predatory sea slugs of the genus Phyllodesmium are reported to feed on Xeniidae species.
G. ventalina is a fan-shaped colonial coral with several main branches and a latticework of linking smaller branches. The skeleton is composed of calcite and gorgonin, a collagen-like compound. The calyces in which the polyps are embedded are in two rows along the branches.
This soft coral was first described in 1766 by the Russian naturalist Peter Simon Pallas who named it Parerythropodium coralloides.It was later determined on the basis of its growth forms, the nature of its spicules (small skeletal elements) and the passages in its coenenchyme (the tissue uniting the polyps) that it should be included in the genus Alcyonium and it was renamed Alcyonium ...
Embedded in this are the coral polyps, each of which is a filter feeder and extends its eight tentacles to catch plankton drifting past with the current. [3] The tissues contain symbiotic dinoflagellate algae Symbiodinium spp. which are photosynthetic and use sunlight to create organic carbon compounds which are then available to the host coral ...
