They have eight tentacles and are also called octocorallia.

The Medusozoa appear to be a sister group to Octocorallia.

Lanthanocephalus is a cnidarian monotypic genus of coral in the subclassis Octocorallia.

He specialized in the study of Octocorallia, a taxonomic subclass that includes sea pens, sea fans and soft corals.

Subclass Octocorallia / Alcyonaria (soft corals and sea pens)

Corals belonging to the subclass Octocorallia have polyps with eight tentacles and octameric radial symmetry.

Echinoptilidae is a family of sea pens, a member of the subclass Octocorallia in the phylum Cnidaria.

Soft corals, including the precious coral (Corallium rubrum), belong to the subclass Alcyonaria, sometimes called Octocorallia.

Originally the members of the family Gorgoniidae included a much wider range of genera than it does now and was used for all of the horny Octocorallia.

Anthozoa is subdivided into two subclasses Octocorallia and Hexacorallia which form monophyletic groups and generally show 8-way and 6-way symmetry in polyp structure respectively.

Related orders in the subclass Octocorallia include Sea pens, Sea fans, Sea whips, Bamboo coral and Xenias.

Bamboo coral, family Isididae, is a family of mostly deep-sea coral of the phylum Cnidaria, class Anthozoa, and subclass Octocorallia.

They are distinguished from the other subclass of Anthozoa, Octocorallia, in having six or fewer lines of symmetry in their body structure and only single rows of tentacles.

Sometimes, in a wider sense, applied to all the Anthozoa, expert the Alcyonaria, whether forming corals or not.

Compound coelenterates of the subclass or order Alcyonaria have polyps with eight-branched tentacles and eight septa.

Subclass Octocorallia / Alcyonaria (soft corals and sea pens)

Soft corals, including the precious coral (Corallium rubrum), belong to the subclass Alcyonaria, sometimes called Octocorallia.

Coenothecalia (also known as Helioporacea) is an order of the class Alcyonaria that forms massive lobed crystalline calcareous skeletons in colonial corals.

Octocorallia (also known as Alcyonaria) is a subclass of Anthozoa comprising 3,000 species of water-based organisms formed of colonial polyps with 8-fold symmetry.
