How do giant squid regulate their temperature?

Answer 1

The giant squid must keep its body temperature regulated because it will suffocate in warm water. To keep itself cool, it remains in cooler water and migrates as necessary.

Answer 2

Giant squid are poikilotherms, which means their body temperature varies with that of their surroundings. They are known to inhabit cold, deep ocean waters where temperature changes are minimal, helping them maintain a relatively stable internal temperature. Additionally, their large body size and low surface area-to-volume ratio helps to mitigate heat loss.
