Poecilosclerida
Poecilosclerida is an order of the demosponge class. It is the most speciose demosponge order with over 2200 species (World Porifera Database). It contains about 25 recognised families. They are characterised by having chelae microscleres, that is, the minute spicules scattered through the tissues, usually in the 10-60 μm range, have a shovel-like structure on the end. Most of the families are viviparous with parenchymella larvae that are uniformly ciliated The cilium, plural cilia (), is a membrane-bound organelle found on most types of eukaryotic cell, and certain microorganisms known as ciliates. Cilia are absent in bacteria and archaea. The cilium has the shape of a slender threadlike projecti .... Families As of 2018, the following families are recognized: References {{demosponge-stub ...

Demosponge
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order ( Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are ove ...

Coelosphaeridae
Coelosphaeridae is a family of sponges belonging to the order Poecilosclerida. Species are found across the globe. Description Originally it was believed that this family was restricted to hollow, bladder-like, spherical, club-shaped, tubular, and cushion-shaped growth forms. Other forms, however, were found to have similar spiculation so have since been included, while other genera such as Coelocarteria were removed due to their differing spiculation. This family now contains a diverse array of forms, including fistular (hollow), branching, massive and encrusting sponges. The surface is typically smooth in fistular forms. It is usually irregularly pitted in non-fistular forms, but areolated (colour ringed) pore-fields are absent. The skeletal architecture is similar to that of the myxillid sponges. Both groups are made of a network of tracts that form an isodictyal skeleton. The usual brushes of tomotes assume a partially tangential position. In the bladder-like fistular for ...

Acarnidae
Acarnidae is a family of sponges belonging to the order Poecilosclerida. It has a global distribution, although several genera occur primarily in colder temperate waters, and several have very restricted ranges. It is estimated that there are several hundred species. Description Species form encrusting, massive, fan-shaped or digitate (small, un-splitting branches growing from a spreading base) growth forms that may burrow into the substrate. The species of many genera produce fistules. The outer skeleton is made of tylotes (long, slender megascleres with knobs at both ends) which may be modified to have a spined base as well as strongyles (megascleres with both ends blunt or rounded). These form tangential and/or paratangential tracts, often with an irregular or halichondroid arrangement. The inner skeleton is made of styles (megascleres with end pointed and the other end rounded) or modified styles. These form massive networks to create isodictyal (triangular meshes in whic ...

Crellidae
Crellidae is a family of marine demosponges in the order Poecilosclerida. Characteristics Growth forms are varied and include branching, club-shaped, massive and encrusting. Identification of members of this family is based on microscopic examination of the spicules in their skeleton. The choanosomal A choanosome is an inner region of a sponge, supported on the choanoskeleton, the stucture that contains the choanocyte Choanocytes (also known as "collar cells") are cells that line the interior of asconoid, syconoid and leuconoid body types of ... skeleton is composed of tornotes while the ectosomal skeleton consists of a tangential crust of spined styles or oxeas.

Monanchora Unguifera (Pink Lumpy Sponge)
''Monanchora'' is a genus of demosponges belonging to the family Crambeida. The genus contains 18 species, which have been researched for their potential use in medicine. Description Morphology The species with in ''Monanchora'' vary in their morphology. The genus ''Monanchora'' is defined by belonging to the family Crambeidae while lacking pseudoatrose spicules. The structure of the species belonging to the genus ''Monachora'' varies from encrusting to lobate to ramose. A typical identifying characteristic of this genus is a canal system that is swollen and has a light colored lining. This canal system collapses when taken out of water. Species in this genus have simple skeletal arrangements that can develop bushes at the surface without the use of ectosomal skeletons. The spicules observed vary among and within species and can be categorized by size into two groups: megascleres and microscleres. In some species the microscleres may be reduced, absent or modified, resulti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
