Dormancy and Metabolic Suppression in Brine Shrimp Cysts
Quick fact
Brine shrimp cysts can remain in a state of nearly zero metabolism for years, and they are so resilient that some have been hatched after being in space for months.
Why this is interesting
Imagine a tiny creature that can be completely dried out, frozen, or even sent into space, and then come back to life decades later. How does it survive without any of the normal requirements for life?
