BLUE SHARK 11.tif
Being cold-blooded, blue sharks lack any mechanism to regulate their body temperature.
So after feeding at depth, they must rise to the surface to digest their food in the warm water that affords a higher metabolic rate, and faster digestion.
That done, they descend to the cool depths once more—to chill out, as it were, and conserve precious energy for the next nocturnal hunt.
