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.
The Clathrinida are an order of calcareous sponges found in marine environments. These sponges have an asconoid structure and lack a true dermal membrane or cortex. The spongocoel is lined with choanocytes.
Homoscleromorpha is a class of marine sponges composed of two families: Plakinidae and Oscarellidae.
Axinellidae is a family of sponges in the order Axinellida.
Clathrina izuensis is a sponge species in the genus Clathrina. The species is named after the Izu peninsula where the holotype was collected.
Clathrina multiformis is a species of calcareous sponge from Russia.
The genus name Aaata has been described as a synonym to two species in the Microcionidae family of sea sponges (Demospongiae). The two species being:
Racekiela ryderi is a species of freshwater demosponge in the family Spongillidae. It was first described by Edward Potts in 1882. It was collected on Sable Island in 1899 by John Macoun, a biologist with the Geological Survey of Canada, and given the name Heteromeyenia macouni by A.H. Mackay in 1900. It was originally assumed to be endemic to Sable Island but is now considered to be the same species as Racekiela ryderi, which is more broadly distributed.
Myxillina is a suborder of poecilosclerid sponges.
Dictyoceratida is an order of sponges in the subclass Ceractinomorpha containing five families. Along with the Dendroceratida, it is one of the two orders of demosponges that make up the keratose or "horny" sponges, in which a mineral skeleton is minimal or absent and a skeleton of organic fibers containing spongin, a collagen-like material, is present instead.
Guancha apicalis was thought to be a species of calcareous sponge in the genus Guancha from Antarctica. It actually never existed.
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.
Chondrocladia concrescens, is a carnivorous sponge in the Cladorhizidae family. It is thought that the object known as the Eltanin Antenna may be an individual of this species. Alexander Agassiz described the sponges as having "a long stem ending in ramifying roots, sunk deeply into the mud. The stem has nodes with four to six club-like appendages. They evidently cover like bushes extensive tracts of the bottom."
Amphimedon massalis is a species of sponge in the taxonomic division of Demosponges. The body of the sponge consists of silica needles and sponge fibres and is capable of taking in much water.
Cladorhiza inversa is a species of sponge in the taxonomic category of Demospongiae. The body of the sponge consists of a spicule and fibers and is water absorbent.
Oscarellidae is a family of marine sponges.
Sycon yatsui is a species of calcareous sponge belonging to the family Sycettidae. The scientific name of the species was first published in 1929.
Spongillida is an order of demosponges in the subclass Heteroscleromorpha.
Leucandra villosa is a species of calcareous sponge in the family Grantiidae. The sponge lives in the sea and its sclereid consists of calcium carbonate. The scientific name of the species was first published in 1885 by Lendenfeld.
