Eutardigrada
Eutardigrada are a class of tardigrades (Tardigrada) without lateral appendices. Primarily freshwater bound, some species have secondarily gained the ability to live in marine environments (''Halobiotus''). By cryptobiosis many species are able to live temporarily in very dry environments. More than 700 species have been described. The order Apochela consists of only one family, Milnesiidae, with two genera: ''Milnesium'' and ''Limmenius''. ''Milnesium tardigradum'' can be found worldwide and is one of the biggest species among tardigrades (up to 1.4 mm); similar-looking species have been found in Cretaceous amber.

Tardigrade
Tardigrades (), known colloquially as water bears or moss piglets, are a phylum of eight-legged segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who called them Kleiner Wasserbär ("little water bear"). In 1777, the Italian biologist Lazzaro Spallanzani named them Tardigrada (), which means "slow steppers". They have been found in diverse regions of Earth's biospheremountaintops, the deep sea, tropical rainforests, and the Antarctic. Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life. Tardigrades have survived exposure to outer space. There are about 1,300 known species in the phylum Tardigrada, a part of the superphylum Ecdysozoa consisting of animals th ...

Hypsibius Dujardini
''Hypsibius dujardini sensu lato'' is a species complex of tardigrade in the class Eutardigrada. A member of this complex, ''Hypsibius exemplaris'', is widely used for various research projects pertaining to evolutionary biology and astrobiology. ''H. exemplaris'' was differentiated from ''H. dujardini sensu stricto ''Sensu'' is a Latin word meaning "in the sense of".

Earlier studies refer to this lab species from northwest England as ''H. dujardini''. ''H. dujardini s.s.'' is found in France, and has differences in 18S rRNA sequence and morphological details. Habitat The species, ''Hypsibius dujardini'', is a tardigrade that prefers freshwater lakes, rivers, and streams. Because they are considered cosmopolitan, their geographical range is immense.
