They have been recorded at depths exceeding 2,200 meters, combining crushing pressure with near-freezing temperatures.

Greenland sharks inhabit Arctic and deep North Atlantic waters that often remain between -1°C and 4°C, temperatures that would rapidly debilitate most large vertebrates.

Specialized biochemical adaptations allow their enzymes and cellular structures to function under constant cold stress where metabolic reactions typically slow to near inactivity.

These adaptations provide rare insight into protein stabilization under extreme pressure and cold, informing cryobiology research and expanding understanding of how life persists at thermal boundaries.
