Andy Casagrande, a world-renowned shark cinematographer, recounts his accidental path from childhood shark obsession through software engineering to filming for National Geographic, Discovery’s Shark Week, and major Hollywood productions, sharing extraordinary stories of close encounters, conservation battles, and the evolving ethics of wildlife filmmaking.
Andy’s origin story: from shark-obsessed kid to accidental filmmaker
A childhood fascination with sharks sparked by TV and books, tempered by parents warning not to believe everything on screen, led to a lifelong obsession.
His father advised becoming a businessman to fund shark adventures, but Andy pursued marine biology, then photojournalism, then psychology after his mother’s paranoid schizophrenia (she once threatened him with a butcher knife at age 11).
A Semester at Sea circumnavigation at 19, including a terrorist attack targeting their ship in Egypt, reshaped his worldview.
After a boring software engineering job in San Francisco during the dot-com boom, he googled great white research teams worldwide, wrote a “Great White Shark Song,” and got invited to Cape Town as an unpaid research cameraman.
National Geographic filmed the research team, the director heard his song, invited him on a coast-of-Africa shoot, and offered him a job — launching his career by accident.
National Geographic vs. Shark Week: the “dark side” of ratings-driven shark TV
Nat Geo cultivated an “explorer” prestige brand (the “yellow border club”), but now chases ratings like everyone else with Shark Fest.
Discovery’s Shark Week was seen as the “dark side”: Jaws-and-claws sensationalism, fear-based programming (“if it bleeds, it leads”), producing 20–30 hours of shark content yearly.
Andy joined Shark Week because no other animal gets 40+ hours of annual programming across networks — it was the only way to film sharks constantly.
He acknowledges both networks now prioritize ratings, but Shark Week’s volume created unprecedented opportunities for shark cinematographers.
High-profile shoots: Mick Fanning, Michael Phelps, MrBeast, and Dolphin Tale
ESPN hired him to film Mick Fanning months after Fanning’s live-streamed great white encounter at Jeffreys Bay; Andy had never filmed surfing, struggled in the lineup, and Fanning later declined shark documentaries, still visibly shaken.
For Shark Week’s “Phelps vs. Shark,” production wanted Michael Phelps to swim at Fish Hoek, South Africa — a beach where two people were consumed by great whites in public (witnesses filmed remains recovered by seagulls). Andy secretly warned Phelps, showing him the International Shark Attack File; Phelps’ team moved the swim.
MrBeast hired him for a shark logistics day off Jupiter, Florida: $100K cash thrown in water among bull sharks for a subscriber challenge (a sidekick retrieved it); MrBeast got seasick, filmed 15 minutes, left his hat — Andy gave it to his son.
On Dolphin Tale (3D, beam-splitter rigs), he met Pete Zuccarini; the Hollywood union rules, rigid departments, miserable veterans, and a set photographer reporting him for a cell-phone photo made him reject feature-film work for wildlife freedom.
Shark behavior, biology, and the limits of scientific knowledge
Great whites hunt seals at dawn/dusk using low sun angle to silhouette prey; tiger sharks use unpredictable timing so prey never learns safe windows.
Great whites start on fish/rays, shift to mammals as teeth calcify; they can go months without eating — metabolism poorly understood, flume (underwater treadmill) studies failed on large whites.
Two tagged great whites (Cape Cod and South Carolina, two years apart) appeared at the same Naples offshore Navy tower on the same night within an hour — Andy suspects they hunt 800-lb Goliath grouper there at night.
Tiger sharks are “Swiss Army knives”: generalist eaters, crafty, unpredictable; great whites more predictable but can have “bad attitudes” (nicknamed “Psycho,” “Biteface”) — scarred individuals more aggressive.
All sharks have two claspers (penises); mating is violent — males bite female pectoral fins, females evolved skin twice as thick. Only one verified great white mating sighting (New Zealand, from a bluff).
Whale sharks have dermal denticles (tiny teeth) on eyeballs for protection — they’re slow, filter-feeders, can’t defend eyes otherwise.
Greenland sharks live 400+ years (carbon-dated vertebrae); polar bear remains found in stomachs — unknown if scavenged or hunted.
Rig sharks (New Zealand) make rapid high-frequency clicks when handled — first recorded active shark sounds (Royal Society Open Science, 2024); suggests sharks may communicate acoustically.
Close calls and attacks: the reality of shark-human encounters
Andy’s wife nearly decapitated by a tiger shark in the Bahamas during a baited shoot: she was filming, let shark leave frame, didn’t watch its head; shark contorted, nictitating membranes covered eyes, mouth opened over her head. Mark Healey (freediving) grabbed dorsal fin, yanked shark away. GoPro corporate demanded footage deletion; Andy kept it but can’t find it.
Fatal Tiger Beach dive (unreported): Austrian diver, experienced, boat drifted in current; she had to swim 150 ft back with multiple tigers in tow. One grabbed her arm, ragdolled her; dive masters couldn’t free her; reef sharks joined; she was consumed. Andy: “They’re not malicious, but they’re capable of whatever they want.”
Kenna (New Zealand sea urchin diver) hit by 5m+ great white at Chatham Islands: shark grabbed weight belt and thigh, lead weights saved him; he surfaced, friends dragged him to boat, applied tourniquets, medevaced. He didn’t tell the story for a decade — “when you think you’re dying, it’s the last thing you want to relive.”
South Australian spearfisherman consumed by 5m great white in front of four buddies swimming formation; shark took him to chest, tail kicking sand on bottom; they watched, screamed, swam away. Tattoo memorial on survivor’s arm.
Drone footage (Australia, California) shows 16-ft whites circling surfers/swimmers, turning away — no bites captured. Santa Barbara swimmer (vet) had 11-ft white swim arm-length away; he later said, “If this is my time, at least I’m in my element.”
Foilers chased for 15 minutes; one knocked off, shark attacked foil board.
Andy’s only unexpected great white encounter: murky South Africa reef dive, husband/wife couple pointed frantically, he turned, shark turned off, he swam toward it (“alpha the shark”), it left. Couple bolted to boat.
Orcas: the only predator great whites fear
Wild orcas never attack humans (only captivity); they’re cultural — NZ orcas eat sharks/rays, not seals; CA/Patagonia orcas eat seals/whales; Norway orcas eat herring.
Ingrid Visser (NZ orca expert) taught Andy: if orcas get bored, act injured/erratic (one fin, circles) — they investigate. He did it; they returned close.
Orcas target great white livers (25% body weight, nutrient-dense); now theory: orcas detect tagged sharks’ 69 kHz pings, use tags to locate liver-rich prey — researchers may inadvertently help orcas hunt whites.
Orcas ramming/sinking boats off Iberia: theory — calf harassed by boats, adults retaliate; they disable rudders, never harm people.
Conservation battles: quotas, NOAA’s “research fishery,” and the shark fin trade
Gulf commercial fishing: Individual Fishing Quota (IFQ) system federalized catch history into tradable quotas — Wall Street buys/leases quota, driving down fisherman pay; “seahab”: crews detox at sea on 10-day trips to earn more drug money.
NOAA Shark Research Fishery (since 2008): issues 200,000 lbs/year sandbar shark quota (admitted overfished) to fishermen who sell whole carcasses — including massive dorsal fins. Andy calls it “subsidized federal shark fin trade.” 18 years of killing for “size, sex, abundance” data.
Fishermen threatened Andy’s family over his opposition to shark kill tournaments; he screenshots but doesn’t police-report — “degenerate fishermen.”
The Cove (Taiji dolphin hunts): dolphin meat (high mercury) fed to schoolkids; Yakuza involved; Rick O’Barry threatened. Andy trained freediving with Kirk Krack (Cove team).
Paul Watson (Sea Shepherd): single pirate ships catch vast % of illegal fish; countries fish maritime zone borders at night with bribed complicity.
Filmmaking philosophy: passion over credentials, YouTube over TV
Andy never went to film school (bad grades, skipped to surf); Dolphin Tale was his film school — he learned from Zuccarini, hated union rigidity.
Jane Goodall had zero academic training, became greatest naturalist — Andy hates “you need a PhD” gatekeeping. Scientists who’ve never seen their study animal underwater (Stanford white shark PhDs refused to cage-dive) vs. Ocean Ramsey (passion, access, inspiration).
Both needed: empirical science + field observation + storytelling. A 15-sec YouTube short reaches billions; a paper reaches thousands.
Shark Week dying down; YouTube is the future — level playing field, $300 GoPro can capture great shots, no gatekeepers.
Andy’s holy grail: film great white mating via fin cameras (remote, no divers). He’s filmed nurse/gray reef mating; whites likely belly-to-belly, males bite fins, claspers cross over.
Polar bears, freediving, and the psychology of wild places
Nat Geo Killer Shots polar bear episode: two failed shoots in James Bay (wrong place, low budget). Andy self-funded Churchill trip ($5K), got bears in two days.
Earlier shoot: producers left him alone on sea ice with high-powered LEDs to attract bears (Inuit avoid fires — bears investigate), no electrified fence (forgot battery), shotgun frozen, snowmobile wouldn’t start, coat caught fire on propane heater, doused with thermos hot chocolate — panic nearly killed him, not bears. Lesson: human error > animal danger.
Freediving > scuba: knows his limits, no gauge anxiety. Scuba close calls: ran out of air at 90 ft in Cayman cave, buddy gave octopus; rapid ascent from 100 ft in self-propelled cage (over-inflated ballast), exhaled all the way, paramedic/O2 on boat.
Cave freediving near-death: swam through reef hole, buddy slow, he pushed on, couldn’t find exit, life flashed in reverse, found tiny light shaft at last second, scraped through.
Anxiety melts in wild places — “most alive underwater with sharks,” hyper-vigilant, not romanticizing. Karma belief: doesn’t kill sharks, doesn’t want it coming back.
Memorable characters and untold stories
Mark Healey: first great white encounter = freedived with it at Guadalupe; speared fish near it; Andy filmed 360° hammerhead fin-cam — shark returned repeatedly, not distressed.
Chris Fallows: iconic Air Jaws breaching photographer; Andy saw first breach on TV Aug 2001, quit software job, moved to Cape Town; Sept 11 attacks next month (his son’s birthday).
Kenna (Skoll): attacked by white shark, survived, now works on Gollum (LOTR); shot The Meg with Statham (calls him “naughty”).
Nick Caloyianis: cameraman bitten in ribs by bull shark after tagging release — shark retaliated.
John Lilly (NASA-funded): sensory deprivation tank inventor; cut dolphin heads open for brain probes; woman lived in flooded house with dolphin, manually stimulated it for vocalizations.
MIT/Harvard (1946–53): fed radioactive isotopes to disabled boys at Walter E. Fernald State School — Clinton declassified.
The big picture: why sharks matter and where media is going
Sharks balance oceans; healthy oceans = 70% of oxygen. “They’ve been here before dinosaurs.”
Fear sells, but media also shifted perception from “only good shark is dead shark” to fascination/conservation.
Andy’s kids now say “I love dolphins” — he pushed sharks too hard. Little people hate being told what to do.
Final thought: “It’s the greatest accident of my life — stumbling into filmmaking for sharks. Met my wife in Serengeti filming lions. Three kids. Said no to jobs for birthdays. YouTube now lets me teach cameras, share passion, no gatekeepers.”
