Cladorhiza is a genus of carnivorous sponges, comprising around 40 species found in oceans around the world. Cladorhiza is the type genus of the family Cladorhizidae.
Polymastia is a genus of sea sponges containing about 30 species. These are small to large encrusting or dome-shaped sponges with a smooth surface having many teat-shaped projections (papillae). In areas of strong wave action, this genus does not grow the teat structures, but instead grows in a corrugated form.
Cladorhiza caillieti is a carnivorous sponge of the family Cladorhizidae described in 2014 from specimens collected from the Juan de Fuca Ridge off the coast of Vancouver Island. It feeds on small crustaceans such as amphipods and copepods. C. caillieti is an elongate, bottlebrush-shaped sponge with filaments projecting from a main stem, and ranges from 7 to 9 cm in height. The specific epithet honors Dr. Gregor M. Cailliet of the Moss Landing Marine Laboratories.
Euplectellidae is a family of glass sponges (Hexactinellids) belonging to the order Lyssacinosa.
Rossellidae is a family of glass sponges belonging to the order Lyssacinosa.
Caulophacus is a genus of glass sponges belonging to the subfamily Lanuginellinae.
Caulophacus elegans is a species of glass sponges belonging to the subfamily Lanuginellinae. The type specimen has been found in Central Kuroshio Current, near Japan.
Staurocalyptus is a genus of sponge. It was circumscribed in 1897 by Isao Ijima.
Amphidiscella is a genus of sea sponge in the family Euplectellidae.
Sceptrulophora is an order of hexactinellid sponges, commonly known as Glass sponges, characterized by sceptrule spicules, that is, "microscleric monactinal triaxonic spicules that include clavules with terminel umbels or smooth heads." Species of the order Sceptrulophora have existed since the Jurassic period, and still flourish today. While there is ongoing debate about the organization of various taxa in Sceptrulophora, the monophyly of the taxon Sceptrulophora is supported by the presence of sceptrules in most of the extant species, and has recently been further supported by DNA sequencing.
Farreidae is a family of glass sponges in the order Sceptrulophora.
Farrea is a genus of glass sponges in the family Farreidae.
Euretidae is a family of glass sponges in the order Sceptrulophora.
