'These sharks are fish eaters, they're not interested in humans,' he said. 'That said, they need to be treated with respect, because they are predators and they have the potential to bite. They're not pets.'

Unlike smooth hammerheads, the increase in white shark sightings is more likely owed to population growth following stricter laws surrounding shark fin removal and harvesting. This increase has also coincided with shifting attitudes towards sharks as the widespread fear of great whites precipitated by 'Jaws' has died down.
Biologists don't yet know what impact the evolving makeup of the regional marine ecosystem will have on local fish populations. However, Chisholm emphasized the importance of reporting shark sightings to scientists like him so that they can continue to gather data on how the changing climate is affecting marine wildlife.

Here's what shark experts do to stay safe in the ocean
Discovery Channel's 'Shark Week' begins Sunday for the 37th year. And Steven Spielberg's movie 'Jaws' celebrated its 50th anniversary in June. Despite the fanfare and some highly publicized reports of shark bites, researchers are quick to point out the apex fish are not the bloodthirsty predators they're made out to be. Instances of sharks biting humans are extremely rare. You're more likely to die falling into a hole at the beach, in a riptide or in an alligator attack than from a shark bite, according to data from the Florida Museum of Natural History's International Shark Attack File. Last year, the museum recorded 47 unprovoked bites worldwide. 'They're not these monster killers that just come flying in whenever there's bait,' said Neil Hammerschlag, a shark researcher based in Nova Scotia, Canada, who charters cage-diving expeditions to bring tourists up close to blue, mako and great white sharks. 'They're very cautious.' Hammerschlag, who's been studying sharks for 24 years, said some are more curious about the color of the boat or the sound of the engine than the 20 pounds of sushi-grade tuna he brings on each trip as bait. Chris Lowe, the director of the Shark Lab at California State University in Long Beach, said he has 'hundreds, if not thousands of hours footage' of sharks near the shore in California. And, most of the time, they're there to relax, he said. For three years, researchers in Lowe's lab surveyed 26 beaches from Santa Barbara to San Diego with drones and saw sharks swim right under surfers without changing course. 'It's like they are ignoring us,' he said. 'We're just flotsam, not food or foe.' The Washington Post asked Hammerschlag and Lowe what they do and the advice they give beachgoers who want to avoid a shark encounter. Lowe said when he's out in the water he spends some time looking behind himself and others, 'like checking my mirrors when I'm driving.' Sharks are stealthy and try to approach other animals from behind. Don't treat the ocean like Disneyland, Lowe said. You're in a wild place where you can't eliminate all risks. His advice: Be vigilant. It will reduce your likelihood of a shark swimming up too closely to investigate you. And, do your homework about the body of water you're swimming in. 'Who are you going to be sharing the ocean with? Is it sharks? Is it stingrays?' Lowe said. 'When we go in the ocean, we are entering someone else's home.' Sharks may confuse a human foot for a fish, or a surfboard for a seal, when visibility is poor, such as in lowlight conditions. Sharks use their mouth and teeth to inspect what's in front of them like we use our hands, Hammerschlag said. 'Most shark bites of people are not predatory,' he said. 'When sharks have bitten people, it seems that they're investigatory or mistaken identity.' The light glimmering off jewelry can look like a fish scale to a shark, Hammerschlag said. He adds reflective stickers to the cage he uses on diving expeditions to try to catch a shark's attention. A fish caught on a line could get the attention of a shark. 'Those vibrations are like ringing the dinner bell for a shark,' Hammerschlag said. However, it can help to swim near other people, Lowe said, since groups of people might be more intimidating than solo swimmers. If you see fish jumping out of water or birds diving for a meal, there could be a 'bait ball' of fish nearby, and that's a feeding opportunity for sharks, Hammerschlag said. There's a myth that a pod of dolphins can ward off sharks. But, he said, the opposite may be the case. 'If there's a big bait ball of fish that dolphins are feeding on, the sharks could be feeing on that, as well,' Hammerschlag said. If you see a shark in the water, don't panic and swim away, Hammerschlag said. If you do, the shark might see you as prey. And, 'you're not going to outswim a shark,' he said. Instead, orient your body so you're always facing the shark and maintain eye contact, Hammerschlag said. Sharks can't sneak up on you if there's no element of surprise. 'You're showing the shark that you see it, and you're responding to it,' he said. 'And that is not a situation that a hunting shark wants to be in.' If you're scuba diving, you can also sit on the ocean floor; sharks tend to approach potential prey from below, Hammerschlag said.

How 'Jaws' Redefined Movie Tech And Ocean Awareness
Director Steven Spielberg on the set of Jaws with the mechanical shark in the background. 'Jaws' is one of the most iconic and instantly recognizable movies ever made. When it premiered in 1975, it didn't just terrify audiences—it reshaped filmmaking technology and introduced groundbreaking techniques that changed cinema forever. National Geographic's new documentary, Jaws @ 50: The Definitive Inside Story, provides a fascinating look into the tools, tech, and improvisation that helped a young Steven Spielberg turn catastrophe into cinematic innovation. Directed by Laurent Bouzereau and produced by Amblin Documentaries in partnership with Wendy Benchley, the documentary offers an unfiltered view into how Spielberg navigated major technical hurdles. I spoke with Benchley about the documentary and the legacy of the movie. Most famously, the mechanical shark—nicknamed "Bruce"—failed so often it became a liability. Spielberg adapted by filming from the shark's point of view, a now-iconic approach that turned absence into tension. 'The genius of Steven,' Benchley notes, 'was knowing when to show less and let the audience imagine more.' Tech Trouble at Sea The film also revisits lesser-known tech struggles, like camera malfunctions from saltwater exposure and the logistical nightmare of ocean shooting. These details underscore a core point: innovation doesn't always start with new technology. Sometimes, it starts with failing technology and a director who's willing to think differently. From Fear to Fascination Incorporating never-before-seen footage from Spielberg's and the Benchley family's archives, the documentary also unpacks the unintended impact of the film on marine life. "We were horrified that some people took 'Jaws' as a license to kill sharks," Wendy Benchley recalls. "We determined then and there to learn about sharks ourselves and fight for their protection." Turning Data into Defense Benchley has since become a global advocate for ocean conservation, helping to drive tech-enabled approaches to protect marine ecosystems. 'We can now track illegal fishing vessels using satellite data, and follow shark migration patterns online in real time,' she explains. 'Technology has been a game-changer for ocean advocacy.' A Legacy of Curiosity That transformation—from shark villain to shark protector—is one of the most compelling narratives in the documentary. Benchley says the legacy of Jaws includes a 30% spike in marine science enrollment at universities shortly after the film's release. 'Peter got thousands of letters from young people who wanted to be the next Matt Hooper,' she says. 'That fascination led to real science.' "Jaws @ 50" premiers on National Geographic on July 10. Creative Impact, Then and Now The documentary also showcases modern filmmakers—including J.J. Abrams, Jordan Peele, and James Cameron—explaining how Jaws shaped their creative process and technical approach. Their reflections show how Spielberg's improvisation set a new benchmark for cinematic problem-solving. Final Cut Fifty years later, Jaws @ 50 reframes a pop culture milestone as a masterclass in creative adaptation. It's a reminder that great storytelling isn't about having the best tools. It's about knowing what to do when those tools break—and turning that breakdown into something unforgettable.
