Most species of shark eat things like fish, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have a very acute sense of smell that allows them to detect blood in the water from miles away.
Great white sharks' most acute sense is smell. If there were just a single drop of blood floating in 10 billion drops of water, they could smell it! Their nostrils are on the underside of the snout and lead to an organ called the olfactory bulb. The great whiteâs olfactory bulb is reported to be the largest of any shark. HEARING
