Polymerurus

	Polymerurus ''Polymerurus'' is a genus of gastrotrichs belonging to the family Chaetonotidae. The genus has almost 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.

picture info	Gastrotrichs The gastrotrichs (phylum Gastrotricha), commonly referred to as hairybellies or hairybacks, are a group of microscopic (0.06-3.0 mm), worm-like, acoelomate animals, and are widely distributed and abundant in freshwater and marine environments. They are mostly benthic and live within the periphyton, the layer of tiny organisms and detritus that is found on the seabed and the beds of other water bodies. The majority live on and between particles of sediment or on other submerged surfaces, but a few species are terrestrial and live on land in the film of water surrounding grains of soil. Gastrotrichs are divided into two orders, the Macrodasyida which are marine (except for two species), and the Chaetonotida, some of which are marine and some freshwater. Nearly 800 species of gastrotrich have been described. Gastrotrichs have a simple body plan with a head region, with a brain and sensory organs, and a trunk with a simple gut and the reproductive organs. They have adhesive gl ...

	Chaetonotidae Chaetonotidae is a family of gastrotrichs in the order Chaetonotida. It is the largest family of gastrotrichs with almost 400 species, some of which are marine and some freshwater. Current classification is largely based on shape and external structures but these are highly variable. Molecular studies show a high level of support for a clade containing Dasydytidae nested within Chaetonotidae. Genera The following genera are included in the family Chaetonotidae according to the World Register of Marine Species: Subfamily Chaetonotinae Kisielewski, 1991 :Genus '' Arenotus'' Kisielewski, 1987 ::''Arenotus strixinoi'' Kisielewski, 1987 :Genus '' Aspidiophorus'' Voigt, 1903 :Genus '' Caudichthydium'' Schwank, 1990 :Genus '' Chaetonotus'' Ehrenberg, 1830 :Genus '' Fluxiderma'' d'Hondt, 1974 :Genus ''Halichaetonotus'' Remane, 1936 :Genus '' Heterolepidoderma'' Remane, 1926 :Genus '' Ichthydium'' Ehrenberg, 1830 :Genus '' Lepidochaetus'' Kisielewski, 1991 :Genus '' Lepidoder ...

	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 ...
