It&#8217;s also widely credited with inspiring generations of shark scientists who revolutionized what we know about sharks, and they continue to uncover new information about these once mysterious and misunderstood creatures.<\/p>\n<p>&#8220;It\u2019s rare that you meet somebody that got involved in shark biology who was not inspired by the movie. It doesn\u2019t matter what age or generation,\u201d\u00a0said <a href=\"https:\/\/www.neaq.org\/person\/john-mandelman\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">John Mandelman, chief scientist and vice president<\/a> of the New England Aquarium\u2019s Anderson Cabot Center for Ocean Life.<\/p>\n<p>Even though sometimes maligned for heightening fears about one of the ocean&#8217;s mightiest predators, &#8220;the &#8216;Jaws&#8217; phenomenon has been far more positive for the outlook on sharks in the grand scheme,\u201d Mandelman said. \u201cIt did elevate their plight and inspire many people, myself included, to get into this field.&#8221;<\/p>\n<p>While sharks often surface in summer conversations given the hordes who visit the beach and the Discovery Channel&#8217;s annual Shark Week, they&#8217;re not just a seasonal phenomenon for shark biologists. They fuel a year-round passion among researchers who are sometimes mystified others don&#8217;t feel the same way.<\/p>\n<p>\u201cIf someone said there was a velociraptor in Tennessee, thousands of people would come from all over the world,\u201d said Gavin Naylor, a geneticist and professor who studies sharks at the University of Florida. \u201cWe\u2019ve got animals in the ocean that are much older than velociraptors and we see them every day. \u201cThey\u2019re so ancient and old they\u2019ve been around since before there were flowering plants.&#8221;\u00a0\u00a0<\/p>\n<p>&#8220;If you\u2019re curious and attentive, the more you look, the more interesting they are,\u201d said Naylor, director of the Florida Program for Shark Research at UF&#8217;s Florida Museum of Natural History. \u201cIt\u2019s kind of frustrating that 90% of the world thinks they\u2019re dangerous and less than .001% of the world thinks they\u2019re really, really cool and that\u2019s the nerds.\u201d\u00a0<\/p>\n<p>New shark facts discovered all the time<\/p>\n<p>When the movie was released in 1975, there were a lot of unanswered questions about sharks. Sharks are hard to study, Naylor said. \u201cIt\u2019s hard to find them. They\u2019re particularly large, and you have to take steps not to get injured.\u201d\u00a0<\/p>\n<p>But there have been huge advances in the five decades since moviegoers first heard Roy Scheider utter the ad-libbed: <a href=\"https:\/\/www.youtube.com\/watch?v=qCzncv0ISaE\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">&#8220;You&#8217;re gonna need a bigger boat.&#8221;<\/a><\/p>\n<p>New things are being discovered all the time, such as new species, as well as information about <a href=\"https:\/\/www.usatoday.com\/story\/news\/nation\/2023\/05\/01\/rare-video-shows-courtship-ritual-oceanic-whitetip-sharks\/11735196002\/\" rel=\"nofollow noopener\" target=\"_blank\">their genetics and reproduction<\/a> and their migration patterns.<\/p>\n<p class=\"related-link\"><a href=\"https:\/\/www.usatoday.com\/story\/news\/nation\/2024\/08\/23\/rare-sawfish-trying-to-make-comeback-off-florida-georgia\/74785593007\/\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">&#8216;Prehistoric&#8217; relative of sharks struggle to make a comeback near Florida<\/a><\/p>\n<p>Scientists have identified 570 or so species of sharks still in existence, Mandelman said. If you include their close relatives, the rays and skates, there are more than 1,000 species around the world, many of which are imperiled.<\/p>\n<p>Studies have shown that white sharks wander great distances, but females <a href=\"https:\/\/www.floridamuseum.ufl.edu\/science\/theres-something-fishy-going-on-with-great-white-sharks-that-scientists-cant-explain\/\" rel=\"nofollow noopener\" target=\"_blank\">return to their home waters to reproduce<\/a>.<\/p>\n<p>Naylor is fascinated by the information that sharks don&#8217;t have many babies, but live a very long time, he said. Although it might seem like an animal with those traits might tend toward extinction, instead, sharks have been through two major extinction events, including\u00a0the Permian (period), \u201cwhen 90% of all life forms on Earth died. And the sharks made it through.\u201d\u00a0<\/p>\n<p>Scientists are interested in how the animals navigated such changes in their environment.\u00a0\u00a0<\/p>\n<p>\u201cWe think they\u2019re super flexible,\u201d Naylor said. \u201cJust like you put on a parka or a rain coat, internally they\u2019ve got all these special tricks to modify how they\u2019re responding to the environmental changes.\u201d\u00a0<\/p>\n<p>\u201cThey\u2019re very resilient and we\u2019d like to understand the architecture of that resilience,\u201d Naylor said. \u201cMy primary passion is to understand how these animals have lasted a long time. They\u2019re really unusual.\u201d\u00a0<\/p>\n<p>Naylor recently co-authored <a href=\"https:\/\/www.pnas.org\/doi\/10.1073\/pnas.2507931122\" rel=\"nofollow noopener\" target=\"_blank\">a study about white sharks.<\/a> They had been reduced to a single population somewhere in the southern Indo-Pacific Ocean, then began to genetically diverge about 7,000 years ago. Researchers have identified three distinct white shark populations, the one in the northern Atlantic, one in the northern Pacific and one in the southern hemisphere around Australia and South Africa.<\/p>\n<p>\u201cThere are probably about 20,000 individuals globally,\u201d Naylor said. \u201cThere are more fruit flies in any given city than there are great white sharks in the entire world.\u201d<\/p>\n<p>About those shark bites<\/p>\n<p>Naylor often talks with people about shark bites, and whether they&#8217;re provoked or unprovoked, thanks to duties that include overseeing the International Shark Attack File at UF\u2019s Museum of Natural History. They maintain a database that keeps track of and classifies <a href=\"https:\/\/www.usatoday.com\/story\/news\/nation\/2024\/02\/05\/fatal-shark-bites-doubled-in-2023\/72426440007\/\" rel=\"nofollow noopener\" target=\"_blank\">all reported shark bites and fatalities<\/a>.<\/p>\n<p><a href=\"https:\/\/www.floridamuseum.ufl.edu\/science\/unprovoked-shark-bites-plummeted-in-2024\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Bites plummeted in 2024.<\/a> So far this year, shark bites have been \u201cabout average,\u201d Naylor said, with no unusual spikes or dips in bites around the world.<\/p>\n<p>They have seen a small dip this year along a stretch of Florida beach often dubbed the \u201cshark bite capital of the world,\u201d he said. Bites are a little lower this year than average along the beach in Volusia County, which includes New Smyrna Beach and Daytona Beach, possibly because of a dredging project underway. He said the county\u2019s shoreline averages 12 to 15 bites or nibbles a year and had seen only four as of late July.\u00a0<\/p>\n<p>Still more to do<\/p>\n<p>When people hear the word sharks, they often think of the 20 or so species of big sharks, Mandelman said. \u201cThere are many, many others that need our focus and they don\u2019t really show up on Shark Week.\u201d<\/p>\n<p>&#8220;It&#8217;s our job as shark biologists to illuminate the plight of the ones that don&#8217;t get as much attention,&#8221; he said. &#8220;We\u2019ve come a long way, but there\u2019s still more to do.&#8221;<\/p>\n<p class=\"related-link\"><strong style=\"margin-right:3px\">My husband wrote &#8216;Jaws.&#8217; <\/strong><a href=\"https:\/\/www.usatoday.com\/story\/opinion\/2025\/06\/20\/ocean-conservation-shark-protection-jaws\/84258732007\/\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">We need to better protect the oceans he loved. | Opinion<\/a><\/p>\n<p>&#8220;We&#8217;ve done a good job at educating the public that sharks have a difficult plate,&#8221; Mandelman said. &#8220;They have more to fear than we do.
