Lissodendoryx Collinsi
''Lissodendoryx collinsi'' is a species of demosponge first found on the coast of South Georgia island, in the south-western Southern Ocean The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-small .... The discovery of ''Lissodendoryx collinsi'' and 14 other new species resulted in increasing the previously reported low sponge endemicity off South Georgia.

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal 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. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

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 ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

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 ...
