Chunellidae is a family of sea pens, a member of the subclass Octocorallia in the phylum Cnidaria.
The World Register of Marine Species list the following genera: [1]
Xenia is a genus of photosynthetic soft marine coral in the family Xeniidae. They resemble a mushroom, with "arms" coming out from the top that end in many-fingered "hands". It is unique among corals because of its ability to use its "hands" to "pulse" or push water away from the colony in a constant, grabbing motion. Common names include fast-pulse Xenia. Species of Xenia are sometimes referred to as pulse corals.
Gorgonia is a genus of soft corals, sea fans in the family Gorgoniidae.
Muricellisis is a genus of deep-sea bamboo coral in the family Isididae, containing two species:
Keratoisis is a genus of deep-sea bamboo coral in the family Isididae, containing the following species:
Scleraxonia is a suborder of corals, a member of the phylum Cnidaria.
Nephtheidae is a family of soft corals in the phylum Cnidaria. Members of this family are known as carnation corals, tree corals or colt soft corals. They are very attractive and show a wide range of rich and pastel colours including reds, pinks, yellows and purples. They are popular with reef aquarium hobbyists.
Gersemia is a genus of soft corals in the family Nephtheidae. Species in this genus are found in cold temperate and polar seas at depths ranging from 20 metres (66 ft) to over 2,000 metres (6,600 ft). The type species is Gersemia loricata.
Funiculana is a genus of sea pens. It is the only genus in the family Funiculinidae. It contains three species:
Melithaea is a genus of octocorals in the family Melithaeidae. Members of the genus are commonly known as fan corals and are found in the tropical Indo-Pacific region. The type species is Melithaea ochracea.
Leptogorgia is a genus of soft coral in the family Gorgoniidae. The genus has a widespread distribution with members being found in the eastern Atlantic Ocean from Western Europe to South Africa, the Mediterranean Sea, the Atlantic coasts of North and South America, the Antilles and the Pacific coast of America. Species are found in both shallow and deep waters.
Plexauridae is a family of marine colonial octocorals in the phylum Cnidaria. Members of this family are found in shallow tropical and subtropical seas. Many species contain symbiotic photosynthetic protists called zooxanthellae.
Stilifer celebensis is a species of sea snail, a marine gastropod mollusk in the family Eulimidae. The species is one of a number within the genus Stilifer.
Nidaliidae is a family of soft corals in the phylum Cnidaria. Some members of this family are similar in appearance to gorgonians. They are difficult to keep in the reef aquarium because they do not contain symbiotic zooxanthellae and therefore need to be fed on zooplankton. Others, in the genera Agaricoidea, Nidalla and Pieterfaurea, more resemble members of the family Nephtheidae and these are somewhat easier to keep in the aquarium.
Siphonogorgia is a genus of soft corals in the family Nidaliidae. Like other members of this family, these corals do not contain symbiotic zooxanthellae.
Anthomastus is a genus of soft corals in the family Alcyoniidae.
Nephthyigorgia is a genus of soft corals of the family Nidaliidae.
Litophyton is a genus of soft corals in the family Nephtheidae.
Chrysogorgia is a genus of soft corals in the family Chrysogorgiidae.
Villagorgia is a genus of gorgonian-type octocorals in the family Plexauridae.
Chunella is a monotypic genus of corals belonging to the family Chunellidae. The only species is Chunella gracillima.
