Milnesium is a genus of tardigrades.[1] It is rather common, being found in a wide variety of habitats across the world.[2] It has a fossil record extending back to the Cretaceous, the oldest species found so far (M. swolenskyi) is known from Turonian stage deposits on the east coast of the United States.[3] Milnesiums are one of the most desiccation and radiation-resistant invertebrates on Earth because of their unique ability to transform into a "tun" state and utilize intrinsically disordered proteins when experiencing extreme environments.[4]
