The blue coral is the only extant octocoral with a massive skeleton, [3] which is composed of fibrocrystalline aragonite (calcium carbonate). It is a hermatypic zooxanthellaete species with either blue or green-grey polyps located within its skeleton, with each containing eight tentacles. Its colonies are either columnar, plate like or branched.
The entire skeleton, however, has an unusual blue color and therefore the species is commonly exploited for decorative uses. [8] The blue color of the skeleton (which is covered with a layer of brown polyps) is caused by iron salts. Blue coral can be used in tropical aquaria, and the crystalline calcareous fibres in the skeletons can be used ...
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]
During the blue light trials, some corals moved up to 220 millimeters (8.7 inches) over a 24-hour period. It’s possible that the corals could have traveled farther, but they had to stop when ...
The resulting structures, such as shells, skeletons, and coral reefs, function as protection, support, and shelter and create some of the most biodiverse habitats in the world. Marine biogenic calcifiers also play a key role in the biological carbon pump and the biogeochemical cycling of nutrients, alkalinity , and organic matter.
Coral calcium is a salt of calcium derived from fossilized coral reefs (primarily from limestone and coastal deposits). It has been promoted as an alternative, but unsubstantiated, treatment or cure for a number of health conditions.
