It’s uncommon that predatory animals like sharks have simply meat of their stomachs. Whereas most sharks primarily prey on fish, marine mammals, and different sea life, they’re nonetheless indiscriminate predators who by accident eat stuff that’s not precisely edible. For millennia people have misplaced, wrecked, or purposely dumped all types of stuff within the ocean. That features all the pieces from clothes and jewellery to priceless paintings and historical artifacts. And on condition that the our trendy oceans are stuffed with plastic, steel, and common flotsam and jetsam, the stuff you’ll find inside a shark’s abdomen more and more resemble the contents of a dumpster.
That’s why inspecting the contents of a shark’s intestine is such an fascinating pursuit, significantly for anglers, marine biologists, and even forensic specialists. We are able to’t resist a good shark story, so we rounded up of a few of the wildest gadgets — and physique components — discovered inside sharks’ stomachs all through historical past.

Earlier than we dive into the roundup of the bizarre stuff sharks eat, let’s get a greater thought of why sharks find yourself consuming all this junk within the first place (and the way they survive the indigestion).
Most marine species are displaying growing indicators of consuming plastic, steel, and different non-food refuse. As these supplies enter the marine meals chain, they work their manner as much as apex predators like sharks. In different phrases, when sharks eat fish they eat all the pieces that fish has eaten, which helps clarify a few of the smaller trash, microplastics, and different oddities discovered inside a shark’s abdomen.
However as the next checklist demonstrates, sharks will generally simply eat trash outright. The truth is, sure species of sharks are extra vulnerable to consuming rubbish than others. Tiger sharks, for instance, are nicknamed the “trash cans of the sea” as a result of they’ll lock their serrated enamel round absolutely anything. Whereas tiger sharks are generally known as one of many prime species liable for unprovoked assaults on people, we additionally know that sharks are likely to explore their surroundings with their mouths. They’ve delicate nerve endings of their enamel and sometimes their exploratory bites may cause fatalities (in people, for example) or lead to an unnatural meal. (Keep in mind, the percentages of dying from a shark assault as we speak are extraordinarily uncommon: Only one in 4.3 million, in accordance with the International Shark Attack File on the Florida Museum.)

Fortunately, shark stomachs comprise acids which might be robust sufficient to finally dissolve steel, in accordance with the Hawaii Department of Land and Natural Resources. Some species are even able to pushing their stomachs inside out, rinsing them, then placing them again in place. However neither of those methods helped sharks digest a few of these really outlandish abdomen treasures we have now found all through historical past.

A sixteenth century French doctor named Guillaume Rondelet recorded this discovery in his Libri de Piscibus Marinis, or “Abstract of Marine Fishes” after discovering the armor in a useless nice white shark. Each the situation of the discover and the way the armor ended up within the water within the first place stay mysteries.
Fur Coats
Talking of protecting outerwear, that 1994 shark exhibit additionally had a fur coat on show. However this wasn’t the one identified occasion of sharks consuming coats. In response to Shark! Killer Tales from Dangerous Depths by Robert Reid, the early twentieth century Australian surgeon and creator V.M. Coppleson spoke of a tiger shark discovered off the coast of the Adriatic Sea that had consumed not one, not two, however three overcoats — plus a nylon raincoat for good measure.
License Plates

The trope of the shark consuming the license plate was popularized after the 1975 launch of — what else — “Jaws,” throughout which Richard Dreyfuss pulls a Louisiana plate out of a tiger shark’s abdomen throughout a autopsy. (Theories circulate across the license plate being a nod to the James Bond sequence with the “007” in the beginning of the plate quantity, as Spielberg wished to work on the British spy film sequence however was turned down.)
An actual license plate (from Florida) has been discovered inside actual shark’s abdomen, and it was additionally on show in that 1994 exhibit. Some anglers hypothesize that steel license plates resemble large steel fishing lures, which set off a fish’s predatory response. There are additionally plenty of license plates on the market, so it’s not stunning that that sharks have eaten their fair proportion.
One Tattooed Human Arm

In 1935 a tiger shark was hooked from an Australian seashore and brought to the Coogee Aquarium and Swimming Baths in Sydney. It was laborious to overlook it when the shark regurgitated an entire, heavily-tattooed human arm into the aquarium. The invention of the distinctive arm began what would turn into a monthslong murder investigation involving a boxer-turned-billiards-club proprietor named James Smith. Smith had disappeared mysteriously that April after having lied to his spouse about going fishing.
As a substitute, he had gone to a seashore cottage to go to a buddy identified to be concerned in petty crime. After an insurance coverage rip-off fell by means of, investigators theorized that Smith’s buddy murdered and dismembered Smith, then packed him in a barrel and tossed him out to sea. (It’s not clear if the barrel broke aside at sea, a shark bit into the barrel itself or, maybe strangest of all, the arm merely didn’t match into the barrel and was tossed overboard.)
Smith could have met an unlucky finish, however his resting place inside a shark’s abdomen is way from distinctive. Human stays have been discovered inside greater than only one shark. We all know sharks have eaten loads of people over the centuries; what’s outstanding is catching one earlier than it digests its meal.
An Whole Reindeer
Few sharks could be able to swallowing a mature reindeer entire. Nice white sharks come to thoughts, however their ranges don’t precisely overlap with that of a reindeer. So leeave it to the Greenland shark, the world’s longest-living vertebrate that swims within the North Atlantic and Arctic oceans, to swallow reindeer whole, together with components of a horse. Greenland sharks are identified to feed on carrion and are sometimes drawn to smelly spots like business fishing operations.
Greenland sharks can reside as much as 400 years. Whereas they’re largely understudied as a consequence of their distant and reclusive nature, they’re thought of a globally susceptible species. They will develop to some 21 ft lengthy and weigh as much as 2,255 kilos.(This video of Swedish kayak angler Joel Abrahamsson catching and releasing one weighing 1,225 kilos is price watching.) A fisherman named Terje Nordtvedt caught the IGFA all-tackle Greenland shark report in Trondheimsfjord, Norway on Oct. 18, 1987. The shark weighed 1,708 kilos 9 ounces.
An Unopened Bottle of Wine
In 1942 the crew of a French fishing trawler discovered an outdated bottle of Portuguese madeira wine within the abdomen of a 6.5-foot blue shark. Madeira is a fortified wine made within the Portuguese islands of the identical title. In response to Atlas Obscura, madeira was typically made and aged on transatlantic ships headed from Europe to the North American continent, which drove a excessive demand for it. With this a lot wine continually at sea, it’s unsurprising {that a} bottle ended up overboard. The French fishermen allegedly sampled the booze and located it to be in completely drinkable situation.

Coppleson, the physician who wrote concerning the disembodied arm in Sydney, additionally extracted the entrance half of a bulldog with a leash round its neck from a tiger shark present in Sydney Harbor. The bulldog was accompanied by limbs from a number of completely different inventory animals, together with pigs, sheep, and even chunks of horse. Coppleson additionally found a special tiger shark off Bondi Seashore (close to Sydney), whose abdomen contents included a mature spaniel canine with a collar nonetheless fixed round its neck.
Migrating Songbirds
In 2017 a study revealed within the analysis journal Ecology revealed that child tiger sharks within the Gulf of Mexico have been overwhelmingly consuming songbirds as they migrated over the big expanse of ocean. Mississippi State College researcher Marcus Drymon led a group of scientists to catch and pump the stomachs of some 107 child tiger sharks earlier than releasing them into their residence waters. Of these sampled specimens, 41 of them had remnants of songbird meals previous.

“Tiger sharks will see a simple meal and snatch it up, however I used to be stunned to study that the sharks have been consuming songbirds — I assumed that they’d be seabirds,” co-author Kevin Feldheim instructed Science Day by day of the examine. Drymon added, “None of them have been seagulls, pelicans, cormorants, or any type of marine hen.”
Different Unusual Issues Sharks Have Eaten
It’s unimaginable to rattle off all of the bizarre stuff ever to satisfy its finish inside a shark’s abdomen (who is aware of what they’ve digested within the depths of the oceans). Listed here are a couple of different honorable mentions:
- An unopened can of salmon
- A inexperienced iguana from the Galapagos Islands
- A leather-based pockets
