Ascandra izuensis is a species of sea sponge in the family Clathrinidae. The species is named after the Izu peninsula where the holotype was collected.
Ascandra izuensis is a calcareous sponge. It is found in the Central Kuroshio Current, Japan. [1] The sponge consists of loosely branched and anastomosing ascon-tubes directly attached to a substratum. There is no pseudoderm covering the whole colony and no endogastric network. The sponge is rather small and attains a length of about 6 mm. The diameter of the ascon-tubes varies from 0.3 mm to 1 mm and the dermal surface of the tubes have a hispid appearance on account of projecting oxea. The colour of the sponge is yellowish-white when preserved in alcohol. The skeleton of the sponge is composed of triradiates, large and small quadriradiates, and oxea. The tri- and quadriradiates are arranged in a few layers in the sponge wall. The quadriradiates are more numerous than the triradiates and their apical rays project into the gastral cavity. The larger quadriradiates are usually arranged in the dermal skeleton. The oxea occur vertically or obliquely to the surface of the ascon-tubes. [3]
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.
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.
Clathrina multiformis is a species of calcareous sponge from Russia.
Trichogypsia is a genus of calcareous sponges in the order Baerida.
Racekiela ryderi is a species of freshwater sponge in the family Spongillidae. It was first described by Edward Potts in 1882. It was collected on Sable Island in 1899 by John Macoun, a biologist with the Geological Survey of Canada, and given the name Heteromeyenia macouni by A.H. Mackay in 1900. It was originally assumed to be endemic to Sable Island but is now considered to be the same species as Racekiela ryderi, which is more broadly distributed.
