Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. South America’s lush Amazon region is a biodiversity hotspot, which means that every living thing must find a way to co-exist. Even some of the most feared snakes on the planet–anacondas. In a paper published June 16 in the journal Frontiers in Amphibian and Reptile Science, conservation biologists Beatriz Cosendey and Juarez Carlos Brito Pezzuti from the Federal University of Pará’s Center for Amazonian Studies in Brazil, analyze the key points behind the interactions between humans and the local anaconda populations. Ahead of the paper’s publication, the team at Frontiers conducted this wide-ranging Q&A with Conesday. It has not been altered. Frontiers: What inspired you to become a researcher? Beatriz Cosendey: As a child, I was fascinated by reports and documentaries about field research and often wondered what it took to be there and what kind of knowledge was being produced. Later, as an ecologist, I felt the need for approaches that better connected scientific research with real-world contexts. I became especially interested in perspectives that viewed humans not as separate from nature, but as part of ecological systems. This led me to explore integrative methods that incorporate local and traditional knowledge, aiming to make research more relevant and accessible to the communities involved. F: Can you tell us about the research you’re currently working on? BC: My research focuses on ethnobiology, an interdisciplinary field intersecting ecology, conservation, and traditional knowledge. We investigate not only the biodiversity of an area but also the relationship local communities have with surrounding species, providing a better understanding of local dynamics and areas needing special attention for conservation. After all, no one knows a place better than those who have lived there for generations. This deep familiarity allows for early detection of changes or environmental shifts. Additionally, developing a collaborative project with residents generates greater engagement, as they recognize themselves as active contributors; and collective participation is essential for effective conservation.

BC: One of the greatest myths is about the Great Snake—a huge snake that is said to inhabit the Amazon River and sleep beneath the town. According to the dwellers, the Great Snake is an anaconda that has grown too large; its movements can shake the river’s waters, and its eyes look like fire in the darkness of night. People say anacondas can grow so big that they can swallow large animals—including humans or cattle—without difficulty. F: What could be the reasons why the traditional role of anacondas as a spiritual and mythological entity has changed? Do you think the fact that fewer anacondas have been seen in recent years contributes to their diminished importance as an mythological entity? BC: Not exactly. I believe the two are related, but not in a direct way. The mythology still exists, but among Aritapera dwellers, there’s a more practical, everyday concern—mainly the fear of losing their chickens. As a result, anacondas have come to be seen as stealthy thieves. These traits are mostly associated with smaller individuals (up to around 2–2.5 meters), while the larger ones—which may still carry the symbolic weight of the ‘Great Snake’—tend to retreat to more sheltered areas; because of the presence of houses, motorized boats, and general noise, they are now seen much less frequently. A giant anaconda is being measured. Credit: Pedro Calazans. F: Can you share some of the quotes you’ve collected in interviews that show the attitude of community members towards anacondas? How do chickens come into play? BC: When talking about anacondas, one thing always comes up: chickens. “Chicken is her [the anaconda’s] favorite dish. If one clucks, she comes,” said one dweller. This kind of remark helps explain why the conflict is often framed in economic terms. During the interviews and conversations with local dwellers, many emphasized the financial impact of losing their animals: “The biggest loss is that they keep taking chicks and chickens…” or “You raise the chicken—you can’t just let it be eaten for free, right?” For them, it’s a loss of investment, especially since corn, which is used as chicken feed, is expensive. As one person put it: “We spend time feeding and raising the birds, and then the snake comes and takes them.” One dweller shared that, in an attempt to prevent another loss, he killed the anaconda and removed the last chicken it had swallowed from its belly—”it was still fresh,” he said—and used it for his meal, cooking the chicken for lunch so it wouldn’t go to waste.

Some interviewees reported that they had to rebuild their chicken coops and pigsties because too many anacondas were getting in. Participants would point out where the anaconda had entered and explained that they came in through gaps or cracks but couldn’t get out afterwards because they ‘tufavam’ — a local term referring to the snake’s body swelling after ingesting prey. We saw chicken coops made with mesh, with nylon, some that worked and some that didn’t. Guided by the locals’ insights, we concluded that the best solution to compensate for the gaps between the wooden slats is to line the coop with a fine nylon mesh (to block smaller animals), and on the outside, a layer of wire mesh, which protects the inner mesh and prevents the entry of larger animals. F: Are there any common misconceptions about this area of research? How would you address them? BC: Yes, very much. Although ethnobiology is an old science, it’s still underexplored and often misunderstood. In some fields, there are ongoing debates about the robustness and scientific validity of the field and related areas. This is largely because the findings don’t always rely only on hard statistical data. However, like any other scientific field, it follows standardized methodologies, and no result is accepted without proper grounding. What happens is that ethnobiology leans more toward the human sciences, placing human beings and traditional knowledge as key variables within its framework. To address these misconceptions, I believe it’s important to emphasize that ethnobiology produces solid and relevant knowledge—especially in the context of conservation and sustainable development. It offers insights that purely biological approaches might overlook and helps build bridges between science and society. The study focused on the várzea regions of the Lower Amazon River. CREDIT: Beatriz Cosendey. F: What are some of the areas of research you’d like to see tackled in the years ahead? BC: I’d like to see more conservation projects that include local communities as active participants rather than as passive observers. Incorporating their voices, perspectives, and needs not only makes initiatives more effective, but also more just. There is also great potential in recognizing and valuing traditional knowledge. Beyond its cultural significance, certain practices—such as the use of natural compounds—could become practical assets for other vulnerable regions. Once properly documented and understood, many of these approaches offer adaptable forms of environmental management and could help inform broader conservation strategies elsewhere. F: How has open science benefited the reach and impact of your research? BC: Open science is crucial for making research more accessible. By eliminating access barriers, it facilitates a broader exchange of knowledge—important especially for interdisciplinary research like mine which draws on multiple knowledge systems and gains value when shared widely. For scientific work, it ensures that knowledge reaches a wider audience, including practitioners and policymakers. This openness fosters dialogue across different sectors, making research more inclusive and encouraging greater collaboration among diverse groups. The Q&A can also be read here.

To this day, Jaws remains the best example of Steven Spielberg‘s genius as a filmmaker. He somehow took a middling pulp novel about a killer shark and turned it into a thrilling adventure about masculinity and economic desperation. And to the surprise of no one, the massive success of Jaws spawned a lot of knockoffs, a glut of movies about animals terrorizing communities. None of these reach the majesty of Jaws, of course. But here’s the thing—none of them had to be Jaws. Sure, it’s nice that Spielberg’s film has impeccably designed set pieces and compelling characters, but that’s not the main reason people go to animal attack movies. We really just want to watch people get attacked. And eaten. With such standards duly lowered, let’s take a look at the best animal attack movies that came out in the past half-century since Jaws first scared us out of the water. Of course this list doesn’t cover every movie inspired by Jaws ( for example Godzilla Minus One, which devotes its middle act to a wonderful Jaws riff), and some can argue that these movies were less inspired by Jaws than other nature revolts features, such as Alfred Hitchcock‘s The Birds. But every one of these flicks owes a debt to Jaws, either in inspiration or simply getting people interested in movies about animals eating people. Those warning aside, lets make like drunken revelers on Amity Island and dive right in! 20. Sharknado (2013) Sharknado almost doesn’t belong on this list because it’s less a movie and more of a meme, a precursor to Vines and TikTok trends. Yes, many fantastic movies have been made off of an incredibly high concept and a painfully low budget. Heck, that approach made Roger Corman’s career. But Sharknado‘s high concept—a tornado sweeps over the ocean and launches ravenous sharks into the mainland—comes with a self-satisfied smirk. Somehow, Sharknado managed to capture the imagination of the public, making it popular enough to launch five sequels. At the time, viewers defended it as a so bad it’s good-style movie like The Room. But today Sharknado‘s obvious attempts to be wacky are just bad, making the franchise one more embarrassing trend, ready to be forgotten. 19. Orca (1977) For a long time, Orca had a reputation for being the most obvious Jaws ripoff, and with good reason—Italian producer Dino De Laurentiis, who would go on to support Flash Gordon, Manhunter, and truly launch David Lynch‘s career with Blue Velvet, wanted his own version of the Spielberg hit. On paper he had all the right ingredients, including a great cast with Richard Harris and Charlotte Rampling, and another oceanic threat, this time a killer whale. Orca boasts some impressive underwater cinematography, something that even Jaws largely lacks. But that’s the one thing Orca does better than Jaws. Everything else—character-building, suspense and scare scenes, basic plotting and storytelling—is done in such a haphazard manner that Orca plays more like an early mockbuster from the Asylum production company (makers of Sharknado) than it does a product from a future Hollywood player. 18. Tentacles (1977) Another Italian cheapie riding off the success of Jaws, Tentacles at least manages to be fun in its ineptitude. A giant octopus feature, Tentacles is directed by Ovidio G. Assonitis, a man whose greatest claim to fame is that he annoyed first-time director James Cameron so much on Piranha II: The Spawning that he activated the future legend’s infamous refusal to compromise with studios and producers. Tentacles somehow has a pretty impressive cast, including John Huston, Shelly Winters, and Henry Fonda all picking up paychecks. None of them really do any hard work in Tentacles, but there’s something fun about watching these greats shake the the octopus limbs that are supposed to be attacking them, as if they’re in an Ed Wood picture. 17. Kingdom of the Spiders (1977) Spielberg famously couldn’t get his mechanical shark to work, a happy accident that he overcame with incredibly tense scenes that merely suggested the monster’s presence. For his arachnids on the forgotten movie Kingdom of the Spiders, director John “Bud” Cardos has an even more formative tool to make up for the lack of effects magic: William Shatner. Shatner plays Rack Hansen, a veterinarian who discovers that the overuse of pesticides has killed off smaller insects and forced the tarantula population to seek larger prey, including humans. These types of ecological messages are common among creature features of the late ’70s, and they usually clang with hollow self-righteousness. But in Kingdom of the Spiders, Shatner delivers his lines with such blown out conviction that we enjoy his bluster, even if we don’t quite buy it. 16. The Meg (2018) The idea of Jason Statham fighting a giant prehistoric shark is an idea so awesome, it’s shocking that his character from Spy didn’t already pitch it. And The Meg certainly does deliver when Statham’s character does commit to battle with the creature in the movie’s climax. The problem is that moment of absurd heroism comes only after a lot of long sappy nonsense. Join our mailing list Get the best of Den of Geek delivered right to your inbox! It’s hard to figure out who is to blame for The Meg‘s failure. Director Jon Turteltaub hails from well-remembered Disney classics Cool Runnings and National Treasure. But too often he forgets how to pace an adventure film and gives into his most saccharine instincts here. One of the many Chinese/Hollywood co-produced blockbusters of the 2010s, The Meg also suffers from trying to innocuously please too wide an audience. Whatever the source, The Meg only fleetingly delivers on the promise of big time peril, wasting too much time on thin character beats. 15. Lake Placid (1999) I know already some people reading this are taking exception to Lake Placid‘s low ranking, complaining that this list isn’t showing enough respect to what they consider a zippy, irreverent take on a creature feature, one written by Ally McBeal creator David E. Kelley and co-starring Betty White. To those people, I can only say, “Please rewatch Lake Placid and then consider its ranking.” Lake Placid certainly has its fun moments, helped along by White as a kindly grandmother who keeps feeding a giant croc, Bill Pullman as a dumbfounded simple sheriff, and Oliver Platt as a rich adventurer. Their various one-liners are a pleasure to remember. But within the context of a movie stuffed with late ’90s irony, the constant snark gets tiresome, sapping out all the fun of a killer crocodile film. 14. Open Water (2003) Like Sharknado, Open Water had its fans for a few years but has fallen in most moviegoers’ esteem. Unlike Sharknado, Open Water is a real movie, just one that can’t sustain its premise for its entire runtime. Writer and director Chris Kentis draws inspiration from a real-life story about a husband and wife who were accidentally abandoned in the middle of the ocean by their scuba excursion group. The same thing happens to the movie’s Susan Watkins (Blanchard Ryan) and Daniel Travis (Daniel Kintner), who respond to their predicament by airing out their relationship grievances, even as sharks start to surround them. Kentis commits to the reality of the couple’s bleak situation, which sets Open Water apart from the thrill-a-minute movies that mostly make up this list. But even with some shocking set pieces, Open Water feels too much like being stuck in car with a couple who hates each other and not enough like a shark attack thriller. 13. Eaten Alive (1976) Spielberg’s artful execution of Jaws led many of the filmmakers who followed to attempt some semblance of character development and prestige, even if done without enthusiasm (see: Orca). Not so with Tobe Hooper, who followed up the genre-defining The Texas Chainsaw Massacre with Eaten Alive. Then again, Hooper draws just as much from Psycho as he does Jaws. Neville Brand plays Judd, the proprietor of a sleazy hotel on the bayou where slimy yokels do horrible things to one another. Amity Island, this is not. But when one of the visitors annoy Judd, he feeds them to the pet croc kept in the back. Eaten Alive is a nasty bit of work, but like most of Hooper’s oeuvre, it’s a lot of fun. 12. Prophecy (1979) Directed by John Frankenheimer of The Manchurian Candidate and Grand Prix fame, Prophecy is easily the best of the more high-minded animal attack movies that followed Jaws. This landlocked film, written by David Seltzer, stars Robert Foxworth as Dr. Robert Verne, a veterinarian hired by the EPA to investigate bear attacks against loggers on a mountain in Maine. Along with his wife Maggie (Talia Shire), Verne finds himself thrown into a conflict between the mining company and the local Indigenous population who resist them. Prophecy drips with an American hippy mentality that reads as pretty conservative today (“your body, your choice” one of Maggie’s friends tells her… to urge her against getting an abortion), making its depictions of Native people, including the leader played by Italian American actor Armand Assante, pretty embarrassing. But there is a mutant bear on the loose and Frankenheimer knows how to stage an exciting sequence, which makes Prophecy a worthwhile watch. 11. Piranha 3D (2010) Piranha 3D begins with a denim-wearing fisherman named Matt, played by Richard Dreyfuss no less, falling into the water and immediately getting devoured by the titular flesh-eaters. This weird nod to Matt Hooper and Jaws instead of Joe Dante’s Piranha, the movie Piranha 3D is supposed to be remaking, is just one of the many oddities at play yhere. Screenwriters Pete Goldfinger and Josh Stolberg have some of the wacky energy and social satire of the original film, but director Alexandre Aja, a veteran of the French Extreme movement, includes so much nastiness in Piranha 3D that we’re not sure if we want to laugh or throw up. Still, there’s no denying the power of Piranha 3D‘s set pieces, including a shocking sequence in which the titular beasties attack an MTV/Girls Gone Wild Spring Break party and chaos ensues. Furthermore, Piranha 3D benefits from a strong cast, which includes Elizabeth Shue, Adam Scott, and Ving Rhames. 10. Anaconda (1997) With its many scenes involving an animal attacking a ragtag group on a boat, Anaconda clearly owes a debt to Jaws. However, with its corny characters and shoddy late ’90s CGI, Anaconda feels today less like a Jaws knockoff and more like a forerunner to Sharknado and the boom of lazy Syfy and Redbox horror movies that followed. Whatever its influences and legacy, there’s no denying that Anaconda is, itself, a pretty fun movie. Giant snakes make for good movie monsters, and the special effects have become dated in a way that feels charming. Moreover, Anaconda boasts a enjoyably unlikely cast, including Eric Stoltz as a scientist, Owen Wilson and Ice Cube as members of a documentary crew, and Jon Voight as what might be the most unhinged character of his career, second only to his crossbow enthusiast from Megalopolis. 9. The Shallows (2016) The Shallows isn’t the highest-ranking shark attack movie on this list but it’s definitely the most frightening shark attack thriller since Jaws. That’s high praise, indeed, but The Shallows benefits from a lean and mean premise and clear direction by Jaume Collet-Serra, who has made some solid modern thrillers. The Shallows focuses almost entirely on med student Nancy Adams (Blake Lively), who gets caught far from shore after the tide comes in and is hunted by a shark. A lot of the pleasure of The Shallows comes from seeing how Collet-Serra and screenwriter Anthony Jaswinski avoid the problems that plague many of the movies on this list. Adams is an incredibly competent character, and we pull for her even after the mistake that leaves her stranded. Moreover, The Shallows perfectly balances thrill sequences with character moments, making for one of the more well-rounded creature features of the past decade. 8. Razorback (1984) Jaws, of course, has a fantastic opening scene, a thrilling sequence in which the shark kills a drunken skinny dipper. Of the movies on this list, only Razorback comes close to matching the original’s power, and it does so because director Russell Mulcahy, who would make Highlander next, goes for glossy absurdity. In the Razorback‘s first three minutes, a hulking wild boar smashes through the rural home of an elderly man in the Australian outback, carrying away his young grandson. Over the sounds of a synth score, the old man stumbles away from his now-burning house, screaming up into the sky. Sadly, the rest of Razorback cannot top that moment. Mulcahy directs the picture with lots of glossy style, while retaining the grit of the Australian New Wave movement. But budget restrictions keep the titular beast from really looking as cool as one would hope, and the movie’s loud, crazy tone can’t rely on Jaws-like power of suggestion. 7. Crawl (2019) Alexandre Aja’s second movie on this list earns its high rank precisely because it does away with the tonal inconsistencies that plagued Piranha 3D and leans into what the French filmmaker does so well: slicked down and mean horror. Set in the middle of a Florida hurricane, Crawl stars Kaya Scodelario as competitive swimmer Haley and always-welcome character actor Barry Pepper as her father Dave, who get trapped in a flooding basement that’s menaced by alligators. Yet as grimy as Crawl can get, Aja also executes the strong character work in the script by Michael Rasmussen and Shawn Rasmussen. Dave and Haley are real people, not just gator-bait, making their peril feel all the more real, and their triumphs all the sweeter. 6. Piranha (1978) Piranha is the only entry on this list to get a seal of approval from Stephen Spielberg himself, who not only praised the movie, even as Universal Pictures planned to sue the production, but also got director Joe Dante to later helm Gremlins. It’s not hard to see why Piranha charmed Spielberg, a man who loves wacky comedy. Dante’s Looney Tunes approach is on full display in some of the movie’s best set pieces. But Piranha is special because it also comes from legendary screenwriter John Sayles, who infuses the story with social satire and cynicism that somehow blends with Dante’s approach. The result is a film about piranha developed by the U.S. military to kill the Vietnamese getting unleashed into an American river and making their way to a children’s summer camp, a horrifying idea that Dante turns into good clean fun. 5. Slugs (1988) If we’re talking about well-made movies, then Slugs belongs way below any of the movies on this list, somewhere around the killer earthworm picture Squirm. But if we’re thinking about pure enjoyable spectacle, it’s hard to top Slugs, a movie about, yes, flesh-eating slugs. Yes, it’s very funny to think about people getting terrorized by creatures that are famous for moving very, very slowly. But Spanish director Juan Piquer Simón, perhaps best known for his equally bugnuts giallo Pieces (1982), pays as little attention to realism as he does to good taste. Slugs is filled with insane and ghastly sequences of killer slugs ending up in unlikely places, swarming the floor of someone’s bedroom or inside a fancy restaurant, and then devouring people, one methodical bite at a time. 4. Deep Blue Sea (1999) When it comes to goofy ’90s CGI action, it’s hard to top Deep Blue Sea, directed by Renny Harlin and featuring sharks with genetically enhanced brains. Deep Blue Sea doesn’t have a strong sense of pacing, it lacks any sort of believable character development, and the effects looked terrible even in 1999. But it’s also the only movie on this list that features LL Cool J as a cool chef who recites a violent version of the 23rd Psalm and almost gets cooked alive in an oven by a genius-level shark. It’s scenes like the oven sequence that makes Deep Blue Sea such a delight, despite its many, many flaws. The movie tries to do the most at every turn, whether that’s clearly reediting the movie in postproduction so that LL Cool J’s chef becomes a central character, stealing the spotlight form intended star Saffron Burrows, or a ridiculous Samuel L. Jackson monologue with a delightfully unexpected climax. 3. Alligator (1980) In many ways, Alligator feels like screenwriter John Sayles’ rejoinder to Piranha. If Joe Dante sanded down Piranha‘s sharp edges with his goofy humor, then Alligator is so filled with mean-spiritedness that no director could dilute it. Not that Lewis Teague, a solid action helmer who we’ll talk about again shortly, would do that. Alligator transports the old adage about gators in the sewers from New York to Chicago where the titular beast, the subject of experiments to increase its size, begins preying on the innocent. And on the not so innocent. Alligator shows no respect for the good or the bad, and the film is filled with scenes of people getting devoured, whether it’s a young boy who becomes a snack during a birthday party prank or an elderly mafioso who tries to abandon his family during the gator’s rampage. 2. Grizzly (1976) Grizzly stands as the greatest of the movies obviously ripping off Jaws precisely because it understands its limitations. It takes what it can from Spielberg’s masterpiece, including the general premise of an animal hunting in a tourist location, and ignores what it can’t pull off, namely three-dimensional characters. This clear-eyed understanding of everyone’s abilities makes Grizzly a lean, mean, and satisfying thriller. Directed by blaxploitation vet William Girdler and written by Harvey Flaxman and David Sheldon, Grizzly stars ’70s low-budget king Christopher George as a park ranger investigating unusually vicious bear attacks on campers. That’s not the richest concept in the world, but Girdler and co. execute their ideas with such precision, and George plays his character with just the right amount of machismo, that Grizzly manages to deliver on everything you want from an animal attack. 1. Cujo (1983) To some modern readers, it might seem absurd to put Cujo on a list of Jaws knockoffs. After all, Stephen King is a franchise unto himself and he certainly doesn’t need another movie’s success to get a greenlight for any of his projects. But you have to remember that Cujo came out in 1983 and was just the third of his works to get adapted theatrically, which makes its Jaws connection more valid. After all, the main section of the film—in which mom (Dee Wallace) and her son Tad (Danny Pintauro) are trapped in their car and menaced by the titular St. Bernard—replicates the isolation on Quint’s fishing vessel, the Orca, better than any other film on this list. However, it’s not just director Lewis Teague’s ability to create tension that puts Cujo at the top. Writers Don Carlos Dunaway and Lauren Currier key into the complicated familial dynamics of King’s story, giving the characters surprising depth. It’s no wonder that Spielberg would cast Wallace as another overwhelmed mom for E.T. The Extraterrestrial the very next year, proving that he still has a soft spot for animal attack movies—even if none of them came close to matching the power of Jaws.
