What do Copper Sharks eat?
The diet of these sharks consists mainly of bony fish, cuttlefish, skates, stingrays, squid, sardines and even Dogfish Sharks. The annual sardine run that occurs along the east coast of South Africa attracts a lot of predators, with Copper Sharks being the most numerous of all the sharks that prey on the sardines. The sardines comprise 69 – 95 % of these specific Copper Shark’s diet. Seemingly cooperative hunting has been observed, comprising of large numbers of Copper Sharks in a group. Schools of prey are herded into a tight ball, with the sharks taking turns to rush into the ball of fish, mouth agape. A “wing” formation is adopted by the group of sharks, in the case of larger prey and Tuna, forcing the prey closer together, with each shark targeting a specific, single prey.
