Few animals captivate people's imagination like sharks. From the enduring cultural legacy of Jaws, which celebrated its 50th anniversary this year, to the continued popularity of the Discovery Channel's Shark Week, now in its 37th year, media portrayals of the apex predator can shape public perception, illuminate their role within Earth's ecosystems, and influence conservation efforts.
For Cameron Perry, every week is shark week. The Georgia Tech alumnus earned his Ph.D. in ocean science and engineering in 2024 and now leads the whale shark and manta ray initiatives at Georgia Aquarium.
As a 6-year-old listening to his mother read him Twenty Thousand Leagues Under the Sea and imagining the creatures Captain Nemo encountered, Perry had dreams of exploring the oceans for himself. When he saw his first whale shark in Georgia Aquarium's 6.3-million-gallon tank, he set out to learn as much as he could about the gentle giants and help to conserve the endangered species.
Perry's research has taken him around the world to observe whale shark behaviors in St. Helena and the Galapagos Islands, working to understand their migration habits, reproduction, and global ecology. While most people won't encounter sharks daily as he does, Perry sees the aquarium as well as the media as effective tools in showcasing sharks in the proper light.
"They are kind of mysterious and unknown. For many people, they've never encountered sharks in their lifetime, and part of that captivation could lead to fear, but education can turn that fear into wonder and awe. There's a narrative that these animals are mindless eating machines, but the more you learn, you realize that's not the case," he said. "These creatures have existed for 400 million years; they're older than trees, and understanding their role on our planet is important to changing the narrative around sharks."
Perry likens sharks to the white blood cells of the ecosystems in which they live, as they help prevent the spread of disease through the consumption of dead or diseased prey, contribute to population control, and provide balance to the ocean's biodiversity.
Understanding Our Role
While at Georgia Tech, Perry worked alongside Regents' Chair and Harry and Anna Teasley Chair in Environmental Biology Mark Hay, whose research has highlighted the role that sharks, and other large predators, play in habitat regulation within coral reefs. Hay explains that overfishing and other human activities have decimated shark populations in certain parts of the world, significantly affecting coral reefs and the populations that rely on them.
As the manager of a freshwater beach in Kentucky in 1975, Hay saw firsthand the impact that Jaws had on the beachgoing public at the time - including his lifeguards.
"I had about 25 lifeguards, and I made them swim a mile every day on our buoy line. After we all went to see Jaws, about half of them refused to swim the mile for over a week. They'd look at me and say, 'You can fire me. I'm not going in,' and I'd laugh and say, 'We're in freshwater. Jaws isn't in there.'"
Hay said that while the movie remains a favorite of his, its depiction of sharks isn't representative of their behavior in the wild, as shark attacks are often accidents, not predatory actions. Like Perry, Hay believes that education can help protect sharks and bring a renewed focus to solving the ongoing issues facing the oceans.
"These ecosystems are degrading, and it's us that's doing it. What I am trying to do in my teaching is to go beyond cataloging the demise and take a more Georgia Tech-type approach by saying, 'If the bridge is broken, we have to be the ones to rebuild it,'" he said.
Hay keeps a saber-toothed tiger fossil on his desk as a constant reminder to himself that "everything I study was shaped by what used to be here," and how understanding nature can help preserve it for the future. Sharks are a captivating species, and both Perry and Hay stress that continued research and a commitment to education are the key to their conservation.
