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 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 the whole lot from clothes and jewellery to priceless paintings and historic artifacts. And on condition that the our fashionable 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 analyzing the contents of a shark’s intestine is such an attention-grabbing pursuit, significantly for anglers, marine biologists, and even forensic specialists. We will’t resist a good shark story, so we rounded up of among 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 displaying rising indicators of consuming plastic, steel, and different non-food refuse. As these supplies enter the marine meals chain, they work their means as much as apex predators like sharks. In different phrases, when sharks eat fish they eat the whole lot that fish has eaten, which helps clarify among 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. In truth, sure species of sharks are extra liable 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 tooth round absolutely anything. Whereas tiger sharks are often known as one of many high species accountable 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 tooth and sometimes their exploratory bites could cause fatalities (in people, as an example) or end in an unnatural meal. (Keep in mind, the percentages of dying from a shark assault in the present day are extraordinarily uncommon: Only one in 4.3 million, in accordance with the International Shark Attack File on the Florida Museum.) 

Fortunately, shark stomachs include acids which can be sturdy sufficient to ultimately 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 now have found all through historical past.

There are additionally numerous 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.

Smith could 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.

They will develop to some 21 toes 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.)

In accordance with 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 continuously 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.

Canine (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 completely different inventory animals, together with pigs, sheep, and even chunks of horse. Coppleson additionally found a special tiger shark off Bondi Seaside (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 printed 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 massive 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 shocked to be taught that the sharks have been consuming songbirds — I assumed that they’d be seabirds,” co-author Kevin Feldheim advised Science Each day of the examine. Drymon added, “None of them have been seagulls, pelicans, cormorants, or any form of marine hen.”

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 below are just a few different honorable mentions:
