}}Paragorgia arborea is a species of coral in the family Paragorgiidae, commonly known as the bubblegum coral. It grows in depths between {{convert|200|m|ft}} and {{convert|1300|m|ft}} at temperatures between {{convert|2|C|F}} and {{convert|8|C|F}}.[2][3] It is found widespread in the northern Atlantic Ocean including on seamounts and knolls, and was first described by the Swedish naturalist Carl Linnaeus in 1758.[1] DescriptionParagorgia arborea can grow to heights of {{convert|6|m|ft}}, and are brightly coloured white, pink, red or orange, in a branching, fan-shaped structure with a tough central trunk and many branches. The branch tips are bulbous giving this octocoral its common name of bubblegum coral.[3]Distribution and habitatParagorgia arborea is well established in the North Atlantic Ocean where it generally grows at depths between {{convert|200|and|1300|m|ft|-2}}. It occurs along the entire Norwegian coast, and at depths of {{convert|40|m|ft}} in Norwegian fjords, especially those with poor visibility and abundant planktonic life.[3] It often grows on reefs created by the stony coral Lophelia pertusa. Like other gorgonians, it prefers exposed locations with strong currents.[4] In the western Atlantic, it occurs in Nova Scotia waters including Oceanographer Canyon, off George's Bank, the Grand Banks, Davis Strait, and southern Greenland.[1]EcologyParagorgia arborea is often associated with the Gorgon's Head basket star Gorgonocephalus caputmedusae which uses it as a perch on which to catch plankton drifting past.[4] It sometimes forms denge underwater forests with such octocorals as Primnoa resedaeformis, Paramuricea grandis and Keratoisis ornata and the sea pen Pennatula borealis.[5]References1. ^1 2 {{cite WoRMS |author=van Ofwegen, Leen |year=2015 |title=Paragorgia arborea (Linnaeus, 1758) |id=125418 |accessdate=2015-08-15|db=}} {{corals}}{{Taxonbar|from=Q2672614}}2. ^{{cite web|url=http://eol.org/pages/322525/overview|title=Bubble Gum Coral (Paragorgia arborea)|publisher=Encyclopedia of Life|accessdate=4 September 2014}} 3. ^1 2 {{cite web|url=http://www.seawater.no/fauna/cnidaria/arborea.html|title=Sea Fan - Paragorgia arborea|publisher=SeaWater|accessdate=4 September 2014}} 4. ^1 {{cite web |url=http://www.seawater.no/fauna/cnidaria/arborea.html |title=Sea Fan - Paragorgia arborea |author= |date=2015-05-29 |work=The Marine Flora & Fauna of Norway |accessdate=2015-08-15}} 5. ^{{cite web |url=http://lophelia.org/case-studies/cscanada/cscanada |title=Atlantic Canada |work=Ophelia.org |publisher=Deep-sea Conservation for the United Kingdom Project |accessdate=2015-08-15}} 3 : Alcyonacea|Corals described in 1758|Taxa named by Carl Linnaeus |
