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".
Dendyae is a genus of calcareous sponges in the family Dendyidae.
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. Sponges are mostly asymmetrical, but Leucosolenia is symmetrical.
Grantia is a genus of calcareous sponges belonging to the family Grantiidae. Species of the genus Grantia contain spicules and spongin fibers.
Axinella is a genus of sponges in the family Axinellidae first described in 1862 by Eduard Oscar Schmidt. Species of Axinella occur in the Indian and Pacific Oceans. Most of these sponges are smaller than 20 cm, and have a yellow or orange colour.
Leucandra is a genus of calcareous sponge belonging to the family Grantiidae. Its earliest known fossils are from the Jurassic.
Leuconia is a genus of calcareous sponges in the family Baeriidae. It was described by English anatomist and zoologist Robert Edmond Grant in 1833.
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.
Suberites is a genus of sea sponges in the family Suberitidae. Sponges, known scientifically as Porifera, are the oldest metazoans and are used to elucidate the basics of multicellular evolution. These living fossils are ideal for studying the principal features of metazoans, such as extracellular matrix interactions, signal-receptor systems, nervous or sensory systems, and primitive immune systems. Thus, sponges are useful tools with which to study early animal evolution. They appeared approximately 580 million years ago.
Aaptos is a genus of sea sponges in the family Suberitidae.
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.
Cinachyrella is a genus of marine sponges in the family Tetillidae.
Crella is a genus of marine demosponges in the family Crellidae.
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.
Soleneiscus radovani is a species of calcareous sponge in the family Dendyidae, and was first described in 1999 by Gert Wörheide and John Hooper. The species epithet, radovani, honours Radovan Borojevic for "his substantial and pioneering achievements in calcarean taxonomy".
Vosmaeropsis macera is a species of calcareous sponge in the family Heteropiidae, and was first described in 1886 by Henry John Carter as Heteropia macera, and was later described as Vosmaeropsisis dendyi by Row and Hôzawa in 1931. It is the type species of the genus, Vosmaeropsis. The species epithet, macera, comes from the Latin, macer.
Heteropia is a genus of sponges in the family, Heteropiidae, and was first described in 1886 by Henry John Carter. The type species by monotypy is Heteropia ramosa, which he first called Aphroceras ramosa in the very same publication.
Leucettusa is a genus of sponges belonging to the family Leucaltidae. The species of this genus are mostly known from the Arctic and Antarctic, New Zealand and Southwest Australia.
Fibulia is a genus of sponges belonging to the family Dendoricellidae. The species of this genus are found in Southern South Hemisphere.
