, and that, in fact, sharks really tolerate people and tend to avoid them,” said Neil Hammerschlag, director of the UM Shark Research and Conservation Program, of the study.To find out if this was the case, scientists monitored sharks’ movement using a method called passive acoustic telemetry, according to a U of Miami. Specifically, the scientists outfitted three different species of shark — Bull, Nurse, and Great Hammerhead — with transmitters that emit ultrasonic sounds.
“When a shark swims within a few hundred feet of one of those listening stations, it can detect that transmitter, hears it, and will record that … that shark swam by that location,” Hammerschlag said. Researchers found that sharks were “spending quite a lot of time close to what we call like urban areas.”
