Description
''Callogorgia'' is a genus of soft corals in the familyLife Cycle
''Callogorgia'' can reproduce both sexually and asexually. Mature eggs enter the body cavity and spawned via the mouth. A planktonic disc-shaped larva grows from the fertilized egg. The early growth of tentacles, body cavity, and mouth begins their change into adults. ''Callogorgia'' cling to a surface in the water as they mature into adults.Habitat
''Callogorgia'' can be found in upper bathyal region of the sea between 750–8200 feet deep. ''Callogorgia'' inhabit parts of the ocean across the world, from the Atlantic to the Indo-Pacific. The species ''Callogorgia veriticillata'' is found in the Mediterranean Sea, while other species such as ''C. americana'' are found in the Atlantic. They can reside in brackish water as well, areas with less salinity than true marine environments. Each species of ''Callogorgia'' will bunch together in dense colonies'','' inhabiting a unique site of ecological parameters. They are often found with brittle stars attached to their branchesRelationships
The variety of colonies in ''Callogorgia'' species makes them an ideal habitat for certain brittle stars. The brittle stars have a commensal relationship with the octocorals, with the ophiurans benefitting by the elevation provided by ''Callogorgia'', allowing them to suspension feed. The genus Callogorgia Gray is known for its propensity to form habitats for fauna in the Pacific Ocean and Gulf of Mexico. In experiments carried out in Eastern Tropical Pacific, the octocoral ''Callogorgia'' cf. ''galapagensis'' Cairns was found with specimens of the ''Astrodia'' cf. ''excavata'' ophiuroid. In the Caribbean Sea, ''Callogorgia gracilis'' was found with ophiuroids from the genera ''Asteroschema'' and ''Ophiomitra.'' Cat sharks use ''Callogorgia'' as a nursery habitat by depositing their egg cases on the branches of the sponge. ''Callogorgia'' has also formed associations with copepods, zoanthids, and scale worms. A zoanthid, ''Isozoanthus primnoidus,'' was found to exhibit a parasitic relationship by benefitting from the support of the coral and its sclerites for protection, while consuming the coral's tissue. Threats to ''Callogorgia'' include damage from fishing gear and equipment as they trawl the floor of the ocean, which can change the environment the corals grow in. They are also highly sensitive to climate change and ocean acidification which can hinder the growth of ''Callogorgia.'' Due to being a coral, they grow very slowly, therefore, any change affecting their rate of growth has profound effects and can linger for decades.Species
