Thoosa is a genus of sea sponges in the family Thoosidae.This genus is known for boring holes in corals. It contains sixteen described species.
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. Corals species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
Species in this genus include:
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.
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.
Homosclerophorida is an order of marine sponges. It is the only order in the monotypic class Homoscleromorpha. The order is composed of two families: Plakinidae and Oscarellidae.
Plakinidae is a family of marine sponges composed of seven genera:
Ascandra izuensis is a species of ssea sponge in the family Clathrinidae. The species is named after the Izu peninsula where the holotype was collected.
Clathrina multiformis is a species of calcareous sponge from Russia.
Cliona is a genus of demosponges in the family Clionaidae. It contains about eighty described species.
Amphimedon is a genus of sponges with over 60 described species. In 2009, Amphimedon queenslandica was the first species of sponge to have its genome sequenced.
Ptilocaulis is a genus of demosponges. The species within this genus are usually red or orange. They are often called tree sponges, as they grow many branches from a single stem resembling trees. They can grow to large size.
Ancorinidae is a family of marine sponges belonging to the order of Tetractinellida.
Chondrilla is a genus of sea sponges belonging to the family Chondrillidae.
Homaxinella is a genus of sea sponges in the family Suberitidae. The type species is Homaxinella balfourensis.
Pachymatisma is a genus of sponges belonging to the family Geodiidae.
Guancha apicalis was thought to be a species of calcareous sponge in the genus Guancha from Antarctica. It actually never existed.
Aplysina is a genus of sea sponges in the order Verongiida. It was first authenticated and described by Nardo in 1834.
Agelasida is an order of sea sponges in the class Demospongiae.
Merliida is an order of demosponges in the subclass Heteroscleromorpha.
Spongillida is an order of sea sponges in the subclass Heteroscleromorpha.
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.
