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.
Clathrina is a genus of calcareous sponge in the family Clathrinidae. Several species formerly in Clathrina were transferred to the newly erected genera Arturia, Ernstia, Borojevia, and Brattegardia in 2013. The name is derived from the Latin word "clathratus" meaning "latticed".
Grantia is a genus of calcareous sponges belonging to the family Grantiidae. Species of the genus Grantia contain spicules and spongin fibers.
Tetillidae is a family of marine demosponges. Tetillids are more or less spherical sponges which are found commonly in all marine habitats at all depths throughout the world. They are especially common in sedimented habitats. Over a hundred species have been described in eight genera.
Homoscleromorpha is a class of marine sponges composed of two families: Plakinidae and Oscarellidae.
Iophon cheliferum, the white reticulated sponge, is a species of demosponge which lives on the bottom of the ocean. It is a deep water species found in the south eastern Pacific Ocean and South Africa.
Leucopsila is a genus of poriferans in the family Baeriidae. It contains one species, Leucopsila stylifera, which was originally described as Leuconia stylifera in 1870. The genus was described by Dendy & Row in 1913.
Amphimedon is a genus of sponges with over 60 described species. The genome of one, Amphimedon queenslandica, has been sequenced.
Homaxinella is a genus of sea sponges, demosponges in the family Suberitidae. The type species is Homaxinella balfourensis.
Homaxinella balfourensis is a species of marine demosponge in the family Suberitidae. It is found in the seas around Antarctica and can grow in two forms, either branching out in one plane like a fan or forming an upright club-like structure.
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.
Neopetrosia is a genus of marine petrosiid sponges. It was first established by the American spongiologist Max Walker de Laubenfels in 1932. It contains these 27 species:
Cladorhizidae is a family of demosponges which are carnivorous and prey on crustaceans and other small animals. They are deep sea sponges typically found on oceanic ridges and seamount systems. As of 2017, nine new species have been discovered in the Southwest Indian Ocean Ridge (SWIOR) including: Abyssocladia boletiphora, Ab. corniculiphora, Ab. hemiradiata, Asbestopluma (Asbestopluma) unguiferata, As. (A.) jamescooki, As. (A.) laminachela, As. (A.) pseudoisochela, As. (A.) ramuscula and Chondrocladia (Meliiderma) rogersi.
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 segonzaci 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.
Rossellidae is a family of glass sponges belonging to the order Lyssacinosa.
Baeriidae is a family of calcareous sponges in the class Calcarea. It was named by Borojevic, Boury-Esnault, and Vacelet in 2000. The type genus is BaeriaMiklucho-Maclay, 1870, by original designation, though Baeria is now considered a junior synonym of LeuconiaGrant, 1833.
