Chaetonotida
The Chaetonotida is an order of gastrotrichs. They generally have a tenpin or bottle-like shape. Chaetonotids inhabit both freshwater and marine environments. They can be distinguished from other gastrotrichs by the absence of pores in the pharynx, and by the presence of adhesive glands at the posterior end of the animal only. Most freshwater species are parthenogenetic Parthenogenesis (; from the Greek grc, παρθένος, translit=parthénos, lit=virgin, label=none + grc, γένεσις, translit=génesis, lit=creation, label=none) is a natural form of asexual reproduction in which growth and development .... The smooth or complex cuticle has a variable number of adhesive tubes, and the pharyngeal lumen of Chaetonotids is Y-shaped. A valve may be present at the junction of the pharynx and midgut. The epidermis in most organisms in this order is partly syncytial. The Chaetonotids are divided into two suborders, Multitubulatina and Paucitubulatina. Multitubulatina are ...

Gastrotrich
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 gla ...

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 ...

Gastrotricha
The gastrotrichs (phylum Gastrotricha), common name, 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 (ocean), marine environments. They are mostly Benthos, benthic and live within the periphyton, the layer of tiny organisms and detritus that is found on the seabed and the beds of other Body of water, 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 Order (biology), orders, the Macrodasyida which are marine (except for two species), and the Chaetonotida, some of which are marine and some freshwater.

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...
