From this coral family results 69 descendants [3] in which each species plays a key role in forming habitats for a variety of marine species. Due to their unique trait of possessing a red calcium carbonate skeleton, these corals can be harvested in order to create handcrafted amulets, jewelry and other valuable artifacts, giving rise to its ...
Primnoa (Lamororux, 1812) also known as red tree coral, is a genus of soft corals and the type genus of the family Primnoidae (Milne Edwards, 1857). [1] They are sessile, benthic cnidarians that can be found in the North Pacific, North Atlantic, and Subantarctic South Pacific, [2] and its members often play a vital ecological role as keystone species [3] within their environment as a habitat ...
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).
Melithaea ochracea grows on shallow reefs in the South China Sea between Taiwan and Indonesia.Its range also includes Singapore and Malaysia. [3] In Taiwan, it is the most widespread gorgonian coral and is found on the higher parts of reef fronts where its numerous small polyps can feed at water flow rates varying from 4 to 40 centimetres (1.6 to 15.7 in) per second.
