Leucosolenida
Leucosolenida is an order of sponges in the class Calcarea and the subclass Calcaronea. Species in Leucosolenida are calcareous, with a skeleton composed exclusively of free spicules without calcified non-spicular reinforcements. According to ''Systema Porifera'' (2002), Lucosolenida contains 9 families, ranging from fully asconoid forms (Leucosoleniidae) to fully leuconoid forms. These body plans are on a continuum based on an increasingly complex skeletal system and compartmentalized choanocytes. A few sources (such as the ''Treatise on Invertebrate Paleontology'', 2004) place non-asconoid families into a separate order, Sycettida.''Treatise on Invertebrate Paleontology'' Part E, Revised. Porifera, Volume 3: Classes Demospongea, Hexactinellida, Heteractinida & Calcarea, xxxi + 872 p., 506 fig., 1 table, 2004, availablhere . Leucosolenids have a poor fossil record, with only a few ambiguous grantiid fossils reported from the Jurassic and Carboniferous. Families * Achramo ...

Calcaronea
Calcaronea is a subclass of sea sponges Sponges or sea sponges are primarily marine invertebrates of the animal phylum Porifera (; meaning 'pore bearer'), a basal clade and a sister taxon of the diploblasts. They are sessile filter feeders that are bound to the seabed, and are on ... in the class Calcarea. They are Calcarea with the triactines and the basal system of tetractines sagittal (i.e. the rays of the spicule make unequal angles with each other), exceptionally regular. In ontogeny the first spicules to be secreted are diactines. Choanocytes are apinucleate. Calcaronea have amphiblastula larvae External links * * Sponge subclasses {{calcarea-stub ...

Grantia Compressa
''Grantia compressa'' is a species of calcareous sponge belonging to the family Grantiidae. It is a very common species of rocky shores along the Atlantic coasts of Europe from France northwards. It appears as flattened, purse-shaped vases up to 5 cm long with slit-like oscula at the ends, hanging downwards attached by a stalk to rocky overhangs, often in groups among seaweed Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of ''Rhodophyta'' (red), '' Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as .... This is a pale sponge ranging in color from grey to yellow. The body of sponge looks like a branching tree with slender. Vaselike cylinder of 5to6 mm in diameter. The entire body of the sponge is pierced by numerous holes, the inhalent pores or ostia. The free end of each cylinder communicates outside by large osculum. The osculum is encircled by oscula ...
