The team watches a giant tardigrade fighting a similarly enormous rotifer; another giant water bear bites a man's toe, rendering him comatose for half an hour with its anaesthetic bite. Finally, a four-foot-long tardigrade, waking from hibernation, scares the narrator from his sleep, and he realizes it was all a dream. [69] [70]
The use of tardigrades in space, first proposed in 1964 because of their extreme tolerance to radiation, began in 2007 with the FOTON-M3 mission in low Earth orbit, where they were exposed to space's vacuum for 10 days, and reanimated, just by rehydration, back on Earth. In 2011, tardigrades were on board the International Space Station on STS-134.
Their adaptability has been tested in Low Earth Orbit, according to Guidetti et al. (2012), and the results are crucial for preserving space and lunar habitats for life. [13] Tardigrades can undergo all five types of cryptobiosis, reducing their metabolism to less than 0.01% and their water content to 1% compared to their normal state.

Panarthropoda is a proposed animal clade containing the extant phyla Arthropoda, Tardigrada (water bears) and Onychophora (velvet worms). [3] Panarthropods also include extinct marine legged worms known as lobopodians ("Lobopodia"), a paraphyletic group where the last common ancestor and basal members of each extant panarthropod phylum are thought to have risen.
Johann August Ephraim Goeze (German: [joˈhan ˈʔaʊɡʊst ˈʔeːfʁa.ɪm ˈɡœtsə]; 28 May 1731 – 27 June 1793) was a German zoologist, born in Aschersleben.He is known for the discovery of tardigrades, also called water bears.
Ramazzottius is a genus of water bear or moss piglet, a tardigrade in the class Eutardigrada, named after the Italian zoologist Giuseppe Ramazzotti. Ramazzottius varieornatus (see image) is a terrestrial invertebrate that is extroardinarily tolerant of extreme conditions such as irradiation, chemicals, dehydration and high pressure. [ 2 ]
