The type species is Homaxinella balfourensis.[2] DescriptionHomaxinella was originally included in the sponge family Axinellidae but the structure of the skeleton shows that it lacks a reticulation and has bundles of calcareous spicules at the surface which led to its inclusion in Suberitidae.[2] The members of the genus are rooted to the substrate and have stalks, a much branched habit of growth and an axially condensed choanosomal skeleton. They have an extra-axial skeleton of bundles of megascleres which are exclusively styles, and a profusion of further incoherently arranged styles, in a wide range of sizes. There are no microscleres.[2]SpeciesThe World Porifera Database recognises the following species:[1]
