Asingle, dark gray fin pierces the water at False Bay. It’s a clear morning near Cape Town, South Africa. T e fin belongs to a 1,000-kilogram, male great white shark. T e shark dives deep. 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 his environment. He’ll also rely on his senses. He picks a direction and swims. His


first step in finding prey is to listen. Great whites don’t have ears that stick out. Instead, two small openings above the eyes lead to inner ears. He listens for sounds of prey swimming. Silence.


Searching for Prey Great whites are the largest predatory fish on the planet. T at puts this shark at the top of the food chain. Orcas or larger sharks could be a threat. T e only other danger to him is people. Sharks can be killed by fishing lines


and nets. T ey’re hunted by sports fishers. And poachers sell their fins to make shark fin soup. For now, the water seems to be


safe. T e shark keeps hunting, but the ocean seems silent. So the great white must use another one of his senses to continue hunting.


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