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).
Paramuricea sp. Eunicea sp. Holaxonia is a suborder of soft corals, a member of the phylum Cnidaria. [1] Members of this suborder are sometimes known as gorgonians and include the sea blades, the sea fans, the sea rods and the sea whips.
The prey is secured with the help of sticky mucus, spirocysts (non-venomous harpoon cells) and nematocysts (venomous harpoon cells). The tentacles then bend to push larger prey into the mouth, while smaller, plankton-size prey, is moved by cilia to the tip of the tentacles which are then inserted into the mouth. The mouth can stretch to ...
The World Register of Marine Species list the following genera: [3] Genus Adelogorgia Bayer, 1958; Genus Antillogorgia Bayer, 1951; Genus Eugorgia Verrill, 1868; Genus Eunicella Verrill, 1869; Genus Filigorgia Stiasny, 1937; Genus Gorgonia Linnaeus, 1758; Genus Guaiagorgia Grasshoff & Alderslade, 1997; Genus Hicksonella Nutting, 1910; Genus ...
G. ventalina is a filter feeder.Each polyp extends its eight tentacles to catch plankton drifting past on the current. Its tissues contain symbiotic dinoflagellate Symbiodinium spp., which are photosynthetic and use sunlight to create organic carbon compounds which are then available to the host coral.
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]
Research has shown that measurements of the gorgonin and calcite within species of gorgonian corals can be useful in paleoclimatology and paleoceanography.Studies of the growth, composition, and structure of the skeleton of certain species of gorgonians, (e.g., Primnoa resedaeformis, and Plexaurella dichotoma) can be highly correlated with seasonal and climatic variation.
