intelligent predator such as a shark knows that octopi use ink clouds for camouflage, it might simply
attack the ink cloud blindly, hoping to make contact with the octopus inside. However, some sneaky
octopi will release the ink cloud in one direction and scurry away in another direction, leaving the predator
with nothing but a mouthful of ink. In addition to confusing predators’ sense of sight, these ink clouds also
confuse their sense of smell.
