Chrysogorgiidae is a family of soft corals in the suborder Scleralcyonacea.[1]
Currently the only fossil record for the family are specimens tentatively identified as a member of the genus Radicipes from the Oligocene epoch. It was found in deep-water strata in western Washington State, USA.
Distribution
It is a widely distributed family being found worldwide in deep-sea environments. Most species are found in the Atlantic and Pacific Oceans with only a reports from the Indian Ocean.[2] Chrysogorgiids are the most abundant family of corals on deep sea seamounts southwest of Hawaii.[3]
Taxonomy
The following genera are recognised as members of the family Chrysogorgiidae:[4][5]
- Chrysogorgia Duchassaing & Michelotti, 1864
- Iridogorgia Verrill, 1883
- Metallogorgia Versluys, 1902
- Parachrysogorgia Xu, Zhan & Xu, 2023
- Pseudochrysogorgia Pante & France, 2010
- Radicipes Stearns, 1883
- Ramuligorgia Cairns, Cordeiro & Xu in Cairns et al., 2021
- Rhodaniridogorgia Watling, 2007
Taxonomic history
There have been a number of other genera that have been previously assigned to this family. A recent taxonomic revision based on phylogenomic analysis either found them not to belong to the family or couldn't place them because there was no suitable molecular data for analysis.[5]

- Distichogorgia Bayer, 1979
