It is a deep water, azooxanthellate coral with a semi-cosmopolitan distribution. DescriptionSolenosmilia variabilis grows into small bushy colonies, the dichotomous branches often joining together. It grows from an encrusting base on which there are a few corallites. The branches are thick near the base of the colony but more slender above; sometimes upper branches are just {{convert|3|to|5|mm|in|2}} in diameter. The coenosteum can be smooth and white, granular, glossy and pale grey, or ridged with eight to ten transverse costae. The corallites are up to {{convert|5|mm|in|1}} in diameter, with the septa grouped in sixes, arranged in three or more cycles. Growth of the colony is by intratentacular budding.[3]DistributionS. variabilis has a semi-cosmopolitan distribution. It is widespread in both the Atlantic and Indian Oceans and has a circumpolar distribution in the Southern Ocean. Locations where it has been found include off South Africa, off Prince Edward Island, off Île Saint-Paul, off southeastern Australia, off New Zealand, off South Orkney Islands, off Tristan Island, on the Hjort Seamount (south of Macquarie Island), on the Macquarie Ridge, and on seamounts in the South Pacific and Drake Passage.[2] Its known depth range is {{convert|220|to|2165|m|ft|-1}}.[1]EcologyS. variabilis is a widespread species of deep sea reef-building coral; in the southwestern Pacific it is the dominant coral species on seamounts and rocky substrates in the depth range {{convert|1000|to|1300|m|ft|-2}}.[6] In this location, it is a major part of a diverse community which is easily damaged by deepwater trawling. It is a long-lived species with a growth rate of about {{convert|1|mm|in|2}} per year and it may be adversely affected by ocean acidification and climate change.[3]References1. ^1 2 {{cite WoRMS |author=Hoeksema, Bert |year=2015 |title=Solenosmilia variabilis Duncan, 1873 |id=135168 |accessdate=2015-06-24 }} {{Taxonbar|from=Q3952555}}2. ^1 {{cite web |url=http://invertebrates.si.edu/antiz/taxon_view.cfm?taxon=5668 |title=Solenosmilia variabilis Duncan, 1873 |work=Antarctic Invertebrates |publisher=Smithsonian Museum of Natural History |accessdate=2015-06-24}} 3. ^1 {{cite journal |author1=Fallon, S.J. |author2=Thresher, R.E. |author3=Adkins, J. |year=2014 |title=Age and growth of the cold-water scleractinian Solenosmilia variabilis and its reef on SW Pacific seamounts |journal=Coral Reefs |volume=33 |issue=1 |pages=31–38 |doi=10.1007/s00338-013-1097-y }} 2 : Caryophylliidae|Animals described in 1873 |
