State
Tardigrades are microscopic ecdysozoans capable of entering a dormant, dehydrated state called cryptobiosis, letting them survive extreme temperature, pressure, and radiation.
Show
A dehydrated tardigrade in cryptobiosis survives exposure well beyond what its active, hydrated form could tolerate, then revives once rehydrated.
Watch for
Cryptobiosis nearly stops a tardigrade's metabolism — it is not evidence the organism is immune to damage while active.
