A


single, dark gray fin pierces the glassy


calm of the water at False Bay. It’s a clear morning near Cape Town in South Africa. T e fin belongs to a 1,000-kilogram, male great white shark. T e fin appears only for a moment then disappears as the shark dives deeper. It’s been weeks since this great white last


ate. He’s ready for a meal, but first he has to find one. To search for prey, he’ll rely on both his senses and his environment. He picks a direction and starts


swimming. His first step in finding prey is to listen. Great whites don’t have ears that stick out, but that doesn’t mean their world is silent. He has two small openings above his eyes that lead to his inner ears. He listens intently for sounds of possible prey swimming. At the moment, silence.


Searching for Prey T e great white shark swims along aimlessly. He’s hungry, but he’s not to be rushed. Great whites are the largest predatory fish on the planet. T at puts him at the top of the food chain, with few threats. Orcas or larger sharks could make trouble for him. T e only other danger to him is people. Sharks risk being killed by fishermen’s


fishing lines and nets. T ey’re hunted by sportsfishers and by poachers, who sell the sharks’ fins to make a product called shark fin soup. For now, the water seems empty


of these threats. It’s safe for him to keep hunting. T e ocean is still quiet, though. So the shark uses another one of his senses to continue his hunt.


This great white may have caught the scent of an injured seal.
