The Calcaxonia are a suborder of the Octocorallia . They belong to the gorgonian-like corals.
features
Their flexible, horn-like axial skeleton (medulla) consists of individual fibers of gorgonine , between which aragonite or calcite is embedded. The inside of the medulla is also filled with lime. The central axial skeleton (medulla) partially has nodular, heavily calcareous thickenings (internodes), which alternate in the structure of the medulla with flexible, gorgonine-containing parts (nodes). The medulla is covered by the coenenchyme from which the eight-rayed polyps grow.
Way of life
Most Calcaxonia feed on the smallest of plankton , only in the families Ifalukellidae and Isididae there are some species that live in symbiosis with zooxanthellae and obtain a large part of their nutrients from them.

A phylogenetic analysis of the relationships within the Octocorallia shows the Ellisellidae as a sister group of the sea feathers (Pennatulacea) as a whole.
