Plakinidae is a family of marine sponges. It is composed of seven genera: [1]
Plakinidae and Oscarellidae are the two families that compose the fourth and smallest class of the porifera phylum, Homoscleromorpha. [2]
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.
Stelletta is a genus of sea sponges belonging to the family Ancorinidae.
Tethya is a genus of sea sponges belonging to the family Tethyidae. Members of this genus all have a spherical body form and some are known to be able to move at speeds of between 1 and 4 mm per day.
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.
Clathria is a large genus of demosponges in the family Microcionidae.
Haliclona is a genus of demosponges in the family Chalinidae.
Darwinellidae is a family of sponges in the order Dendroceratida.
Chondrilla is a genus of sea sponges belonging to the family Chondrillidae.
Myxilla is a genus of demosponge belonging to the family Myxillidae. These sponges usually form encrustations on rock surfaces.
Plakortis edwardsi is a species of sea sponge in the order Homosclerophorida, first found in vertical walls of reef caves at depths of about 23 to 28 metres in the Caribbean Sea. This species has diods of a single category, with thick and S-shaped centres ; triods which are T-shaped. It is the only species of this genus exhibiting small diods.
Plakortis myrae is a species of sea sponge in the order Homosclerophorida, first found in vertical walls of reef caves at depths of about 23 to 28 metres in the Caribbean Sea. This species has diods of two categories: large ones which are abundant, and rare small ones with S-shaped centres; triods which are Y- or T-shaped, and possesses abundant microrhabds.
Plakina nathaliae is a species of sea sponge in the order Homosclerophorida, first found in vertical walls of reef caves at depths of about 23 to 28 metres in the Caribbean Sea. It has a leaf-like flat body, which is loosely attached to the substrate and a perforated, unlobate surface; it contains two bacterial morphotypes and is characterized by two mesohylar cell types with inclusions.
Oscarellidae is a family of marine sponges.
Mycale is a genus of demosponge with 240 recognised species in 11 subgenera. It has been a large genus with multiple subdivisions since it was first described in 1867.
Acarnus is a genus of sponges belonging to the family Acarnidae. The genus has almost cosmopolitan distribution.
Phorbas is a genus of demosponges belonging to the family Hymedesmiidae.
Penares is a widely distributed genus of demosponges.
Plakortis is a genus of marine sponges in the order Homosclerophorida, first described by Franz Eilhard Schulze in 1880.
Corticium is a genus of sponges in the order Homosclerophorida. first described by Eduard Oscar Schmidt in 1862.
