Hypsibius Explained

Hypsibius is a genus of tardigrades in the class Eutardigrada.

Genome sequencing

The genome of Hypsibius dujardini has been sequenced.^[1] Hypsibius dujardini has a compact genome and a generation time of about two weeks. It can be cultured indefinitely and cryopreserved.^[2] This sequenced strain has been redesignated Hypsibius exemplaris since 2018.
