The Weirdest Things Ever Found Inside a Shark’s Stomach

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 devour 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 things from clothes and jewellery to priceless paintings and historic artifacts. And provided that the our fashionable oceans are filled with plastic, metallic, and basic flotsam and jetsam, the stuff you will discover 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 will’t resist a good shark story, so we rounded up of a few of the wildest objects — and physique components — discovered inside sharks’ stomachs all through historical past.

Why Do Sharks Eat Rubbish?

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 exhibiting growing indicators of consuming plastic, metallic, 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 things 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 record demonstrates, sharks will generally simply eat trash outright. Actually, sure species of sharks are extra susceptible 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 often known as one of many prime species chargeable 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 infrequently their exploratory bites could cause fatalities (in people, as an illustration) or lead to an unnatural meal. (Bear in mind, the chances of dying from a shark assault in the present day are extraordinarily uncommon: Only one in 4.3 million, based on the International Shark Attack File on the Florida Museum.) 

Fortunately, shark stomachs comprise acids which might be robust sufficient to ultimately dissolve metallic, based on 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.

The Weirdest Stuff Ever Discovered Inside a Shark

A Swimsuit of Metal Armor

A 1994 New York Times article reported on a touring shark exhibit that appeared on the American Museum of Pure Historical past in New York.

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 lifeless nice white shark. Each the placement 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 recognized occasion of sharks consuming coats. Based on 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 collection with the “007” initially of the plate quantity, as Spielberg needed to work on the British spy film collection 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 metallic license plates resemble big metallic fishing lures, which set off a fish’s predatory response. There are additionally lots of license plates on the market, so it’s not shocking that that sharks have eaten their justifiable share.

One Tattooed Human Arm

In 1935 a tiger shark was hooked from an Australian seaside and brought to the Coogee Aquarium and Swimming Baths in Sydney. It was onerous 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 out to be 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 seaside cottage to go to a buddy recognized to be concerned in petty crime. After an insurance coverage rip-off fell by way 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 might have met an unlucky finish, however his resting place inside a shark’s abdomen is much 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 Total Reindeer

Few sharks could be able to swallowing a mature reindeer complete. 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 recognized to feed on carrion and are sometimes interested in smelly spots like industrial fishing operations.

Greenland sharks can stay 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’ll 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 identify. Based on Atlas Obscura, madeira was usually 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 always 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.

Canines (Collars, Leash, and All)

Coppleson, the physician who wrote in regards to 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 totally different inventory animals, together with pigs, sheep, and even chunks of horse. Coppleson additionally found a unique tiger shark off Bondi Seaside (close to Sydney), whose abdomen contents included a mature spaniel canine with a collar nonetheless mounted 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 had been overwhelmingly consuming songbirds as they migrated over the massive expanse of ocean. Mississippi State College researcher Marcus Drymon led a staff 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 had been consuming songbirds — I assumed that they’d be seabirds,” co-author Kevin Feldheim instructed Science Every day of the research. Drymon added, “None of them had been seagulls, pelicans, cormorants, or any form of marine fowl.”

Different Unusual Issues Sharks Have Eaten

It’s unattainable to rattle off all of the bizarre stuff ever to fulfill 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
• A coil of copper wire
• The propeller from an outboard motor
• A bison cover
• A keg of nails
• Porcupine spines

Remaining Ideas

Sharks are curious creatures that discover their environment utilizing all of their senses and talents, and which means biting with their mouths. Sharks each by accident and intentionally eat all types of peculiar objects, significantly as trash continues to pile up in our oceans. Thankfully, they’ve iron-clad stomachs that may usually dissolve even the hardest meals, together with metallic.
