Primnoa
''Primnoa'' also known as red tree coral, is a genus of Alcyonacea, soft corals and the type genus of the family Primnoidae . They are Sessility (motility), sessile, Benthic zone, benthic Cnidaria, cnidarians that can be found in the Pacific Ocean, North Pacific, North Atlantic, and Subantarctic South Pacific, and its members often play a vital ecological role as keystone species within their environment as a habitat and refuge for the megafauna that also inhabit those regions. This, in combination with their slow growth, makes the increasing disturbance to their habitats caused by fishing activities particularly impactful and difficult to recover from. Etymology The name ''Primnoa'' derives from the Greek language, Greek word Πρυμνὼ (''Prymno''), the name of an Oceanids, Oceanid. The name itself is derived from πρυμνός (''prymnos''), meaning “last”, “lowest”, and by extension, “deepest”. Taxonomy The genus ''Primnoa'' was first Species description ...

Primnoa Pacifica
''Primnoa pacifica'' or red tree coral is a species of soft coral in the family Primnoidae. It is a deep water coral found in the North Pacific Ocean, and plays an integral role in supporting benthic The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "t ... ecosystems. Red tree corals grow axially and radially, producing structures of calcite and gorgonian skeletons that form dense thickets. Like other species of coral, red tree coral is made of a soluble form of calcium carbonate, which forms the reef structure, as well as provides food, shelter, and nutrients for surrounding organisms. Amongst the organisms red tree corals provide a home for, many are commercially important fish and crustaceans. These areas of marine habitat are listed as Habitat Areas of Particular Concern.

Narella
''Narella'' (Gray, 1870) is a genus of deep-sea soft corals in the family Primnoidae (Milne Edwards, 1857). They are sessile, bottom-dwelling organisms that can be found in all ocean basins, having cosmopolitan distribution. They have a branching appearance. History Etymology The name ''Narella'' is believed to be derived from the latin ''nares,'' meaning nostril, due to the resemblance of the rows of polyps to small noses. Discovery The present understanding of ''Narella'' and its members was only established in the late 20th century. Prior to that, many members of ''Narella'' were categorized into other genera. While the genus itself was described in 1870 by John Edward Gray, the first species in the genus was described in 1860, ''Primnoa regularis'' (now recognized as ''Narella regularis''). In 1887 several new species of ''Narella'' were discovered by Edward Wright and Théophile Studer, but were described as members of new genera ''Stachyodes'' and ''Calypterinus' ...

Alcyonacea
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals ( Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kep ...
