Paragorgia is a genus of soft coral in the family Coralliidae. It was formerly place in the family Paragorgiidae.

Anthomastus is a genus of soft corals in the family Alcyoniidae.

Heteroxenia is a genus of soft corals in the family Xeniidae.

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 to over . The type species is Gersemia loricata.

Funiculina is a genus of sea pens. It is the only genus in the family Funiculinidae. It contains three species:

Candidella is a genus of corals belonging to the family Primnoidae.

Pleurogorgia is a genus of corals belonging to the family Chrysogorgiidae.

Swiftia is a genus of gorgonian-type octocorals in the family Plexauridae. thumb|right|With tentacles spread for feeding

Acanella is a genus of deep sea corals of the family Keratoisididae. Acanella are mainly studied and found in Hawaii, they are able to survive in high-flow sites and are preyed upon by nudibranch mollusks. It has a high fecundity and small size that allows high dispersal and recruitment; however, it has been classified as a vulnerable marine organism due to its vulnerability to bottom fishing gear.

Plexaurella is a genus of gorgonian-type octocorals in the family Plexauridae. Species of the genus are typically characterised by their slit-pores, however, there are some which lack this distinguishing feature (e.g. P. grisea). Sclerite examination is necessary for species identification, which reveals the characteristic 4-rayed 'butterfly' spicules of the cortex and the lack of purple sclerites in the axial sheath.

Muricella is a genus of corals belonging to the family Acanthogorgiidae.

Callogorgia is a genus of deep sea corals that are ideally suited to be habitats for different organisms. They reproduce both sexually and asexually, clinging to the hard substrate of the ocean during their maturation process. Callogorgia are found at depths ranging from 750-8200 feet in the Gulf of Mexico, Pacific Ocean and the Caribbean Sea. An array of organisms have relationships with Callogorgia, including brittle stars, cat sharks, and copepods. The nature of these relationships are often commensal, with Callogorgia providing a habitat for the organisms.

Paraminabea is a genus of soft corals in the family Alcyoniidae.

Euplexaura is a genus of cnidarians belonging to the family Plexauridae.

Dendrobrachia is a genus of soft corals in the monotypic family Dendrobrachiidae. Dendrobrachiidae is in the order Scleralcyonacea.

Muriceopsis is a genus of gorgonian-type, branching colonial octocorals in the family Plexauridae. They are found on shallow water reefs and are capable of developing sweeper tentacles. The growth of these corals is rapid and they can be kept in a reef aquarium.

Bebryce is a genus of gorgonian-type octocorals in the family Plexauridae.

Paracalyptrophora is a genus of corals belonging to the family Primnoidae.

Eunicea is a genus of gorgonian-type octocorals in the family Plexauridae. These branched octocorals typically have knobby protuberances from which the polyps protrude. They are often stiffened by purple sclerites and some colonies, in brightly lit back-reef areas are purple, though most colonies are brown or grey. The polyps in some species are large and feathery in appearance. The growth of these corals is rapid and they can be kept in a reef aquarium.

Paracis is a genus of corals belonging to the family Plexauridae.

Iciligorgia is a genus of soft coral in the family Melithaeidae. It was formerly placed in family Anthothelidae.

genus of cnidarians

Acanthomuricea is a genus of corals belonging to the family Plexauridae.

Mopsea is a genus of coral belonging to the Mopseidae family. It comprises two species, Mopsea encrinula and Mopsea triaknema, found around the coasts of Australia at depths ranging from . Colonies are orange-brown and grow up to around in size. They comprise multiple branches from which grow feather-shaped structures. Polyps are covered in sclerites and span across the entire colony. The two species can be distinguished by the shape of their sclerites.

Primnoa also known as red tree coral, is a genus of soft corals and the type genus of the family Primnoidae . They are sessile, benthic cnidarians that can be found in the North Pacific, North Atlantic, and Subantarctic South Pacific, and its members often play a vital ecological role as keystone species within their environment as a habitat and refuge for the megafauna that also inhabit those regions. This, in combination with their slow growth, makes the increasing disturbance to their habitats caused by fishing activities particularly impactful and difficult to recover from.
