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.[1]
H. exemplaris was differentiated from H. dujardini sensu stricto in 2018. Earlier studies refers to this lab species from north-west England as H. dujardini. H. dujardini s.s. is found in France, and has differences in 18S rRNA sequence and morphological details.[1]
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. They can be found in regions like the tropics and the poles.[2]
Genome sequencing
The genome of Hypsibius exemplaris has been sequenced.[3][4] Hypsibius exemplaris has a compact genome and a generation time of about two weeks. It can be cultured indefinitely and cryopreserved.[5]
