‘Jaws' made people fear sharks. 50 years later, can it help save them?

‘Jaws' made people fear sharks. 50 years later, can it help save them?

Washington Post20-06-2025
When 'Jaws' debuted in U.S. theaters 50 years ago today, it helped launch a new era in American movies. Steven Spielberg's blockbuster about a bloodthirsty great white terrorizing a beach town also stoked fear and fascination, exacting a toll on sharks.
After 450 million years of evolutionary history, shark populations are collapsing, and more than a third of shark species and their relatives face extinction. Now scientists are trying to use the lure of 'Jaws' to advance shark conservation efforts.
With the exception of surfers and fishermen, people 'didn't think about sharks much' 50 years ago, said David Shiffman, a marine conservation biologist at Arizona State University. But after 'Jaws' was released, many summer beachgoers began to worry about sharks, even though attacks on humans are rare. Last year, there were 28 confirmed unprovoked bites in the United States — and only 47 worldwide.
This excessive fear of sharks was termed the 'Jaws effect' and helped fuel a surge in shark-fishing competitions — especially targeting white sharks.
Although sportfishing posed a threat to sharks, Shiffman said the most significant impact of 'Jaws' was more indirect. When the film came out, industrial fishing was just beginning to ramp up, and the risks posed to shark populations by commercial fisheries have become clear over time.
'Unsustainable fishing practices are the single largest threat to marine biodiversity, including but not limited to sharks, more so than climate change, more so than plastic pollution, more so than oil spills,' Shiffman said.
Following the release of 'Jaws,' efforts to protect sharks lost traction. The lack of movement to curb indiscriminate fishing techniques or take specific action to prevent the targeting of sharks for their fins and meat led to sharp declines in global shark populations.
An estimated 100 million sharks are killed each year, according to studies, and the global number of oceanic sharks and rays has declined by 71 percent since 1970.
'We know over the last 50 years, in the period really since 'Jaws' came out, that shark populations worldwide have been absolutely smashed by fishing,' said Colin Simpfendorfer, a shark fisheries researcher at James Cook University in Australia. 'We didn't do a lot about it because a lot of people thought sharks were bad and getting rid of them was probably a good thing.'
In 2022, Congress attempted to address the issue of shark finning — the practice of chopping the valuable fins off live sharks and dumping their bodies overboard. But banning finning in the United States has had little effect on the practice in international waters, especially in Asia, where the fins are prized as the main ingredient in shark fin soup.
Studies have shown that bans on finning have been largely unsuccessful as long as the sale of shark meat remains legal.
The European Union restricts the trade in shark fins, and the 2022 Convention on International Trade in Endangered Species of Wild Fauna and Flora expanded protections for 97 shark species and further restricted the international shark trade, but effective enforcement remains a challenge.
Citizen-led efforts across the world have gained momentum, including the launch of the Asian Shark and Ray Alliance this year to drive conservation across the continent. An increase in dive tourism has also spurred protection efforts in Southeast Asian nations like the Maldives and Indonesia.
For endangered sharks, it's a race against time to gather information that might help save them. And while 'Jaws' might have contributed to the harms of unsustainable fishing practices, researchers and conservationists are now attempting to use the film to further scientific understanding and influence public policy.
'It created a fascination with sharks, and people began to realize we don't know that much about them, and a huge amount of research has happened on sharks and exploration of their lives in the last 50 years,' said Steve Palumbi, a marine biologist at Stanford University.
Wendy Benchley, a conservation advocate and widow of author Peter Benchley, who wrote the novel on which 'Jaws' is based, said the enthusiasm generated by the film has been a powerful tool.
'Thousands of people around the world wrote letters to Peter saying, 'Oh I'm just riveted by sharks, I can't wait to learn more,' ' Benchley said. ' 'Jaws' has, and I have, been working on this for 50 years. So this moment is important because people are concentrating on sharks and on 'Jaws.' '
This interest has driven scientific advances that enabled researchers to study sharks' responses to pollution, stress and environmental change. The key to that research can be found in sharks' jaws: their teeth.
Shark teeth, which are replaced every few weeks, can number in the thousands over a shark's lifetime. The chemical makeup of the teeth can reveal information about the environment the sharks lived in. And increasingly, their accumulation — or absence — is helping track how human activity has reshaped ocean life.
'There's been some really interesting work to reconstruct the population of sharks to understand exactly when human populations start to really affect sharks, and how dramatic that effect has been,' Simpfendorfer said.
Recent studies have also confirmed sharks' importance to maintaining coastal food ecosystems, with significant human implications.
'Understanding the role they play in ecosystems is a powerful argument for understanding why we should protect them,' Shiffman said. 'We want healthy food chains off our coasts because they provide billions of humans with food and tens of millions of humans with jobs. And to have a healthy food chain, you need a healthy top of the food chain.'
Yet as shark populations hurtle toward extinction, the perception issue persists.
Other apex predators such as tigers, polar bears and lions have benefited from forceful worldwide conservation campaigns that have translated into legal protections. But sharks haven't received the same degree of attention.
'Jaws' has already given white sharks a much-needed boost, and conservationists are hoping this will translate to other species.
'Great white sharks are actually one of the best studied and best protected species of sharks, and that is in no small part because of the fascination from 'Jaws,' ' Shiffman said. 'There are many other species that are doing much, much worse. There are many shark species that don't have five scientific papers about them.'
In the United States, some researchers are noticing a greater harmony between the public and sharks.
'Over the last five to eight years, more and more sharks have been hanging around the beaches of Cape Cod,' Palumbi said. 'It's led to more people realizing that they have to give way, that they have to share space with white sharks, and that means moving someplace else to swim, not going to places that the white sharks are hunting.'
John Baker, president and chief program officer at WildAid, a conservation group, is hoping this trend will continue.
'With the spotlight back on 'Jaws' after 50 years, we kind of need to elevate the image of sharks as the 'polar bear of the ocean,' ' Baker said.

Report: WWE SmackDown To Extend Three-Hour Format

WWE SmackDown may not return to a two-hour format… yet. 2025 began with WWE SmackDown running as a three-hour show on the USA Network, instead of its usual two hours. This was a significant change for the blue brand, which had largely been a two-hour show since its inception in 1999. Triple H later mentioned in January that this change was only temporary and that SmackDown would go back to two hours later. Advertisement In September 2024, WrestleVotes reported SmackDown would switch back to two hours in June after many three-hour episodes. Last month, WrestleVotes confirmed this again and said the change would likely happen with the June 6 episode of SmackDown, with Dave Meltzer also confirming this detail. However, recent reports from PWInsider say that things might not go as expected. The reports mentioned that the USA Network had internally listed WWE SmackDown as running three hours long in early June. This means the show might continue with the longer, three-hour format instead of going back to the usual two-hour format. It remains to be seen how much longer this format will last, but it looks like SmackDown will be a three-hour show a bit longer. WWE SmackDown May 23rd match card update The May 23 episode of Friday Night SmackDown will air live from the EnMarket Arena in Savannah, Georgia. This show will be the final stop before Saturday Night's Main Event. Below is updated match card for upcoming edition of SmackDown.

Patriots, Blues pay tribute to legendary musician Ozzy Osbourne after singer's death at 76

Legendary metal singer and frontman Ozzy Osbourne died Tuesday. He was 76. Osbourne leaves behind quite the legacy. After a successful (and, at times, controversial) music career — both as a solo artist and as the frontman for Black Sabbath — Osbourne was introduced to an entirely new audience on the MTV reality show "The Osbournes." Given the hard-rocking, energetic nature of some of his most popular songs, Osbourne made a few appearances at NFL games over his career. One of those appearances came prior to a New England Patriots game in 2005. The Patriots used Black Sabbath's "Crazy Train" to introduce its players during the team's dynasty. Prior to the team's opener in 2005, it invited Osbourne to sing the song at the stadium in person. He obliged. The Patriots thanked Osbourne for being the voice of that introduction in a tweet Tuesday. Osbourne made a similar appearance during the Los Angeles Rams' season opener in 2022. Doing a live performance of two songs during halftime as the team took on the Buffalo Bills. His sports moments weren't limited to just NFL games. In 2003, he appeared at a Chicago Cubs game, where he sang an ... interesting ... rendition of "Take Me Out to the Ball Game" with his wife Sharon. Osbourne also found himself connected to the St. Louis Blues thanks to an unfortunate image. In 1984, Osbourne was arrested for public intoxication. In his mugshot, Osbourne is wearing a Blues jersey. He had played in St. Louis a few days before the arrest. Osbourne, however, decided to poke fun at the moment years later. When the Blues were in the midst of a playoff run in 2019, Osbourne tweeted out an image of the mugshot with the message "Let's go @StLouisBlues." He later tweeted out a picture of himself wearing an updated Blues jersey to show he was still supporting the team. The Blues replied to that tweet Tuesday, saying, "St. Louis loves you, Ozzy. RIP."
