Better to run than to have your liver squeezed out.
The great white shark—a fast, powerful, 16-foot-long torpedo that’s armed to the teeth with teeth—has little to fear except fear itself. But also: killer whales.
For almost 15 years, Salvador Jorgensen from the Monterey Bay Aquarium has been studying great white sharks off the coast of California. He and his colleagues would lure the predators to their boats using bits of old carpet that they had cut in the shape of a seal. When the sharks approached, the team would shoot them with electronic tags that periodically emit ultrasonic signals. Underwater receivers, moored throughout Californian waters, detected these signals as the sharks swam by, allowing the team to track their whereabouts over time.
