Completely reversible dehydration of live organisms.

In order to purge the anabiotic process of its spontaneous-generation taint, he says, scientists in this century renamed it cryptobiosis, meaning return to life, or anhydrobiosis, meaning life without water.
Still, he notes, scientists studying anhydrobiosis continue to grapple with the question of life or death.
The technology, based on the principles of anhydrobiosis (life without water), which allows multicellular organisms to survive extreme environments, is providing scientists with the ability to preserve biological samples like RNA and DNA at a fraction of the cost of conventional methods.
Crowe (1974) discusses several types of latent states among tardi grades including anhydrobiosis, the cryptobiotic state induced by desiccation, the state that most limno-terrestrial tardigrades must survive.
