If you picture a showdown between the chirpy dolphin and the toothy shark, you might imagine a pod ramming into the ocean’s iconic predator enough times to eventually kill it. To see such a predator done in by the animals we perceive as the underdogs certainly makes for a compelling role reversal.

“You’ve got these amazingly intelligent, incredible dolphin predators, in social groups with complex social lives, and then the iconic shark,” says Michael Heithaus, a professor in the Department of Biological Sciences at Florida International University and expert in marine predator-prey interactions. “What’s not to love about it?”
