A deep-sea drama is unfolding in the globe of shark science. An fascinating scientific record of a uncommon species in a new spot may well in fact just be a photo of a plastic toy.
By way of published commentary, tweets, and in conversations with Gizmodo, biologists, shark enthusiasts, and other professionals have expressed intense skepticism that an alleged photo of a goblin shark truly shows a after-living animal.
If it have been genuine, the image in query would be the 1st-ever record of the species in the Mediterranean Sea—a notable and critical variety expansion for the uncommon animal. But if it is in fact a image of a toy goblin shark, as various sources recommend, it is a cautionary tale about citizen science, negligent editing and peer assessment, and the stress scientists face to publish new findings as rapidly and often as attainable.
To unravel this shark controversy, let’s commence at the starting.
The Published Record
Final year, scientists published a paper in which they documented a supposed juvenile goblin shark specimen, located dead and washed up on a beach in Greece. It was the 1st time a single of the nightmarish hunting deep sea-sharks had ever been observed in the Mediterranean Sea, according to the write-up published in the journal Mediterranean Marine Science in Might 2022. In that paper, the researchers stated they’d been sent the photograph by a citizen scientist none of the group had personally noticed or examined the specimen.

Goblin sharks are elusive creatures, hardly ever noticed dead or living. Not considerably is identified about their reproduction or habits, in massive portion mainly because they invest most of their lives thousands of feet beneath the surface of the ocean. They are believed to be broadly distributed, and reputable specimens have been located in diverse components of the Atlantic, Pacific, and Indian Oceans. However no a single had ever published proof of a goblin shark in the Mediterranean Sea, till this study.
Months right after that 1st publication, in November 2022, a group of ichthyologists and independent researchers responded with a comment on the initial paper, in the exact same scientific journal, questioning the specimen’s legitimacy. “On close examination of this image…doubts arise about the authenticity,” they wrote. The commenters listed ten motives for their skepticism, from the shape of the jaw and other bits on the “specimen” in the photograph, to the incorrect quantity of gills, the rigidity of the fins, and the lack of detail in the write-up description.
In response, the original study authors published their personal comply with-up comment in January—doubling down on the specimen’s authenticity and attempting to rebut each and every of the issues. Each comments have been published on the net for the 1st time this Monday.
A Rebuttal to a Rebuttal
However with the rebuttal, inconsistencies and far more holes emerged, and the goblin shark truthers stay unconvinced. “In my opinion, it is a model of a such a shark,” stated Jürgen Pollerspöck, an independent shark researcher and lead author of the November 2022 comment, in an e mail to Gizmodo. When he 1st saw the image, he stated he “immediately noticed the ‘unnatural look’ of the shark. Stranded animals usually show injuries or indicators of decomposition.” But the photographed specimen didn’t.
He also pointed out that the original write-up described a supposedly juvenile goblin shark, with an estimated length of 80 centimeters. In their reply, the authors stated that, in fact, the citizen scientist estimated the total specimen length of 17 to 20 centimeters, and it could potentially be a shark embryo, not a juvenile. In Pollerspöck’s view, 20 centimeters is also smaller to be a viable goblin shark, immature, embryonic, or otherwise.
Gizmodo reached out to the lead researcher who had initially published the alleged goblin shark record, as effectively as the editor in chief of the journal. Neither responded by time of publication.
The Web Weighs in
Meanwhile, the ‘is it a true shark’ discussion had shifted on the net. David Shiffman, a shark ecologist and marine biologist, weighed in on Twitter in at least two different threads. In one tweet, Shiffman posted an eBay hyperlink to a model toy goblin shark that appears a especially excellent match for the photo.
Deep-sea ecologist Andrew Thaler also chimed in on Twitter to say he was convinced by the distinct eBay toy. “The mystery comes to an finish. It is a toy shark,” he wrote. In an e mail to Gizmodo, he clarified: “This is outdoors my region of experience… My only comment is that it appears an awful lot like a toy shark.”
Many shark enthusiasts responded to Thaler and Shiffman’s tweets, affirming their observations that the photographed “shark” appears incredibly considerably like the toy shark.
But a single marine researcher took the quest additional. Matthew McDavitt, who is a lawyer by trade but a published independent shark researcher in his absolutely free time, compiled his personal image comparisons and report on the controversy, which he shared with Gizmodo.

The original photo “just looked off,” McDavitt told Gizmodo in a telephone get in touch with. He cited the drooping rostrum, tail, and mouth as issues that didn’t add up with his expertise of actual goblin sharks. He also reiterated Pollerspöck’s concern about size. “It just didn’t appear ideal.”

McDavitt stated this wouldn’t be the 1st time that a false photo had been published as proof of a fish variety expansion (yes, sharks are fish). The researcher relayed a story in which he previously noticed some inconsistencies in a image of a uncommon wedge fish, published as 1st proof of a that species living off the coast of Portugal. In the end, he stated, the image turned out to be from an aquarium. A photographer had fraudulently passed it off as a dive photo.
Circumstances like this, he stated, can have true unfavorable impacts on researchers. McDavitt noted that, in the wedge fish instance, he ended up hearing from some scientists who had been ready to fund an expedition to survey the waters off of Portugal to obtain far more examples of the uncommon fish. Clearly, they would’ve been disappointed.
A marine biologist who requested anonymity out of worry of expert harm told Gizmodo in a telephone get in touch with that he’s quite confident the goblin shark photo is a fake. Upon 1st hunting at the image, he felt it wasn’t ideal, he stated. The scientist explained that this is not how most species records are presented—with a single photograph with out even a scale bar.
Even though he does not know the publishing scientists personally, he does not think they had malicious intentions. In his view, they failed to do due diligence. Irrespective of whether the citizen scientist who sent them the photo knew it wasn’t a true goblin shark or not is not clear, he stated.
Each the marine biologist and McDavitt stated a main situation right here is negligence on the portion of the publishing journal and the common stress inside academia to publish new and fascinating findings. The most accountable and finest outcome right here would be for either the original researchers to withdraw their paper or for the journal to situation a retraction, each stated.
Pollerspöck echoed the sentiment. The lead researcher on the goblin shark study is a student, he pointed out. “In my opinion, the dilemma and duty lies far more with the editor of the journal and the reviewers,” he wrote to Gizmodo. He is “convinced that it was an accident,” on the original authors’ portion.
It is Superb. Is It Plastic?
Marine scientists and shark enthusiasts are not the only ones who told Gizmodo the “goblin shark” specimen appears suspect. Two plastics professionals echoed issues about the veracity of the alleged fish.
“I assume it is incredibly attainable that it could be [a] degraded plastic toy,” Joana Sipe, a plastic degradation researcher at Duke University, told Gizmodo in a telephone get in touch with. Sipe stated she couldn’t possibly be specific, as the only way to figure out the material would be to inspect it straight, but that lots of elements of the photo recommend the “shark” could be a molded synthetic material.
She agreed that the line subsequent to the mouth could simply be a seam from machine-molded plastic. Then there are the flecks of what could be sand, or may well as an alternative be remnant plastic dye sticking to the model. Sipe also pointed out the “L” shaped dark imprint on the tale, which she stated looked like intentional colour shading.
Additional, the droopiness of the tail and rostrum (i.e. shark snout), and faded colour could be the outcome of heat or put on on a plastic toy—especially out in the sun on a Greek beach, Sipe added.
Greg Merrill, a Duke University graduate student who research plastic pollution in marine mammals, also believed the photographed “animal” was a plastic model. “I am not a shark specialist I study whales and plastic,” he wrote to Gizmodo in an e mail. Nonetheless, “I’m confident this is a toy,” he stated.
His critique echoed these of other researchers he also pointed out the lack of photo scale and the lax description in the original publication. He noted that it is extremely uncommon to obtain a completely intact specimen of any marine organism washed up on a beach. “Scavengers—crabs, gulls, etc—are keen on a absolutely free meal and will usually consume soft tissues, like the eyes, pretty much quickly,” Merrill wrote. “This is if the animal ever tends to make it ashore.”
