What is hypobiosis?

Answer 1

Hypobiosis is an arrested state of development that is usually seen with larvae of nematodes. It is where the larvae are in an inactive state for a period of time, then a stimulus of some kind makes them active again (it is not always known what this stimulus is).

Answer 2

hypothermia (i guess that's what you're talking about) is basically freezing to death. you get so cold, your heart slows to the point where it eventually stops.
