Ascandra is a genus of calcareous sponges of the family Leucaltidae and are found in oceans around the world.
As of 2019, 15 valid species of Ascandra are recognized: [1]
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".
Leucosolenia is a genus of calcareous sponges belonging to the family Leucosoleniidae. Species of this genus usually appear as groups of curved vases, up to 2 cm long, each ending in an osculum. The overall shape is sometimes likened to a tiny bunch of bananas. They are most often observed in tide pools, clustered around the base of seaweeds or on rocks, and occur in a variety of colours, usually rather pale. Its canal system is of asconoid type. The colony consists of few simple vase-like, cylindrical individuals each terminating in an osculum and united at their bases by irregular horizontal tubes. Leucosolenia reproduces both asexually and sexually. asexual reproduction by budding and sexual reproduction takes place by formation of gametes, i.e., ova and sperms. Lecosolenia is hermaphrodite, because both the gametes are formed in the body of same individual.
Grantia is a genus of calcareous sponges belonging to the family Grantiidae. Species of the genus Grantia contain spicules and spongin fibers.
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.
Ascandra corallicola is a species of calcareous sponge in the family Leucaltidae. It is known from the coastal waters in northeast Atlantic at depths between 90 and 530 m, and on the Reykjanes Ridge as deep as 1,300 m (4,300 ft). It occurs solely on dead parts of the corals Lophelia pertusa and Solenosmilia variabilis, to which its specific name corallicola refers to.
Leucandra is a genus of calcareous sponge belonging to the family Grantiidae. Its earliest known fossils are from the Jurassic.
Trichogypsia is a genus of calcareous sponges in the order Baerida.
Sycon is a genus of calcareous sponges belonging to the family Sycettidae. These sponges are small, growing up to 7.5 cm and having length from 2.5 to7.5, and are tube-shaped and often white to cream in colour. They are known to aquarium hobbyists as "Pineapple" or "Q-Tip" sponges, and are frequent "hitchhikers" accidentally brought in.
Arturia is a genus of calcareous sponge in the family Clathrinidae which contains 14 species. It is named after Arthur Dendy, a prominent researcher of calcareous sponges. It was renamed Arturia in 2017 because the name Arthuria was already assigned to a genus of molluscs.
Borojevia is a genus of calcareous sponge in the family Clathrinidae. The genus is named after sponge researcher Radovan Borojevic.
Ernstia is a genus of calcareous sponges in the family Clathrinidae. The genus was erected in 2013 to contain five species previously assigned to Clathrina. The genus name honors German naturalist Ernst Haeckel for his contributions towards sponge taxonomy and phylogeny.
Clathrina camura is a species of calcareous sponge from the Atlantic Ocean.
Amphoriscus is a genus of calcareous sponges in the family Amphoriscidae.
Geodia hentscheli is a species of sponge in the family Geodiidae. It is found in the waters of the North Atlantic Ocean. The species was described in 2010 by Paco Cárdenas, Hans Tore Rapp, Christoffer Schander & Ole S. Tendal.
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.
Soleneiscus is a genus of calcareous sponges in the family Dendyidae.
Ascaltis is a genus of sponges in the family Leucascidae, first described in 1872 by Ernst Haeckel.
Leucetta is a genus of sponges in the family Leucettidae, which was first described in 1872 by Ernst Haeckel. The type species is Leucetta primigenia Haeckel, 1872 by subsequent designation.
