Kuarrhaphis is a genus of calcareous sponges in the family Trichogypsiidae. It consists of one species, Kuarrhaphis cretacea. [2]
Sponges, the members of the phylum Porifera, are a basal Metazoa (animal) clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. The branch of zoology that studies sponges is known as spongiology.
The calcareoussponges of class Calcarea are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made out of calcium carbonate in the form of calcite or aragonite. While the spicules in most species have three points, in some species they have either two or four points.
Leucosolenida is an order of sponges in the class Calcarea. Species in the order Leucosolenida are calcareous with a skeleton composed exclusively of free spicules without calcified non-spicular reinforcements.
Calcareous is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines.
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.
Clathrinidae is a family of calcareous sponges in the order Clathrinida. It contains the following genera:
Ascute is a genus of calcareous sponges. It contains two species, both found in Australia:
Baerida is an order of sea sponges in the subclass of Calcaronea, first described in 2000 by Radovan Borojevic, Nicole Boury-Esnault and Jean Vacelet.
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.
Clathrina aurea is a species of calcareous sponge from Brazil. Specimens of this species were previously misidentified with Clathrina clathrus
Arturia canariensis, commonly known as the yellow calcareous sponge, is a species of sponge in the family Clathrinidae. It is found in shallow seas in the Canary Islands, Cape Verde, the Adriatic Sea and the Caribbean Sea. The specific epiphet "canariensis" was given to this species because it was first described from Lanzarote in the Canary Islands.
Clathrina clathrus is a species of calcareous sponge belonging to the family Clathrinidae.
Clathrina conifera is a species of calcareous sponge from Brazil. The species name refers to the cone-shaped appearance of the triactines.
Clathrina lacunosa is a species of calcareous sponge from the British Isles. The species name means "having holes" and refers to the perforations found in the sides of the sponge. It is usually found on vertical solid surfaces at depths down to 220 m. It is distributed in the north-eastern Atlantic from the Arctic to the Mediterranean. It is a fairly common sponge but is often overlooked due to its small size.
Peronidella is an extinct genus of Calcareous sponges found in marine sedimentary rocks dated between the Devonian and the Cretaceous periods.
Clathrina broenstedi is a species of calcareous sponge from the Weddell Sea. The species is named after Holger Brøndsted, a Danish sponge researcher. The only spicules present in this species are triactines.
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.
Trichogypsiidae is a family of sponges in the class Calcarea.
Cliona orientalis is a species of demosponge in the family Clionaidae. It occurs in the Indo-Pacific region and is a bioeroding species, with various specialisations for living on and inside calcareous substrates such as massive corals and molluscs.
Corticium candelabrum is a species of sponge in the order Homosclerophorida. It is native to the eastern Atlantic Ocean and the Mediterranean Sea where it inhabits the shallow sublittoral zone. The type locality is the Adriatic Sea.
