Panagrolaimus superbus is a species of terrestrial free-living

anhydrobiosis for extended periods of time.[2]

Ecology

P. superbus is a non-parasitic terrestrial

Surtsey, Iceland.[5][3]

Metabolism

In order to combat rapid

dj1 and 1 Cys-Prx to help scavenge and reduce reactive oxygen species, mitogen-activated protein kinases that phosphorylate heat shock proteins such as Hsp27 to stabilise microfilaments, and casein kinase 2 that helps in DNA repair, among others.[7] P. superbus's ability to enter anhydriobiosis has given it polyextremotolerance, a tolerance of various extreme environments, being the first multi-cellular organism able to withstand immersion and reproduce in heavy water, albeit with a reduced metabolic rate, withstand immersion in gallium, and tolerate g-forces up to 400,000 times the Earth's.[8][9][10]
