Biochemistry Professor Kenneth Storey from the Storey Lab , has a piece published on squids and their ability to survive the worst of conditions.
Genetic regulation is behind the seasonal hibernation of bears, allows many species to survive in low- or no-oxygen environments and lets others withstand extreme dehydration. It even allows some creatures to endure the freezing, oxygen-deprived, radiation-filled vacuum of space, which may be happening now to the thousands of miroscopic tardigrades that crash-landed on the moon in 2019.
It turns out that is also how krakens survive in the abyss.
