BLUE SHARK 10.tif
Blue sharks feed mainly on squid, which are most accessible when they have ascended into shallower water at night. There the sharks feed in the dark, using only their acute sense of electroreception, virtually mapping the position of their prey even in complete darkness.
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.
