If you've ever wondered what would hap if a cattle carcass got dropped into the South China Sea, you've travel to the close place.
Scientists from China decided to driblet a beefy corpse 1,629 meters down disconnected the continental slope southeast of Hainan Island to spot what it would attract.
For grounds purposes, they stuck a camera down determination with the anticipation of gaining caller insights into the earthy whale autumn processes successful the heavy sea.
So, arsenic the carcass was lying determination connected the seabed, a fig of Pacific sleeper sharks amazingly popped up.
These types of sharks are susceptible of diving to depths implicit 1,000 meters and are highly uncommon to observe successful definite areas. But what the researchers didn't spot coming was the quality successful attack betwixt the feeding strategies of the larger sharks (considered successful the survey arsenic 2.7 meters agelong oregon more) and smaller sharks (less than 2.7 meters long).

The larger sharks looked to beryllium enjoying a spot of beef tartare and viciously attacked the carcass, portion the smaller sharks conscionable circled astir it cautiously.
There was besides a batch of polite queuing behaviour going on, arsenic scientists noticed hierarchical feeding patterns.
“This behaviour suggests that feeding precedence is determined by idiosyncratic competitory intensity, adjacent successful deep-water environments, reflecting a endurance strategy suitable for non-solitary foraging among Pacific sleeper sharks,” said Han Tian from the Sun Yat-sen University and Southern Marine Science and Engineering Guangdong Laboratory successful China.
Perhaps the astir unthinkable discovery, however, was by movie fans successful the comments who noticed a pearly achromatic grin connected 1 of the sharks, reminiscent of Bruce successful Finding Nemo.

"I wouldn’t person expected Bruce from Finding Nemo either but I cognize that grin anywhere," 1 idiosyncratic commented.
A 2nd joked: "Beefs backmost connected the paper boys," portion a 3rd pointed out: "Shark has amended dental health than I do!!?"
"Guys gonna beryllium chasing that beef sensation for the remainder of their lives lol," a 4th quipped, arsenic different questioned whether the 'Shark been swimming circular Turkey'.
Well, scientists didn't expect to spot the shark swimming astir successful the South China Sea, arsenic Tian explained: “Although Pacific sleeper sharks person besides been recovered successful the heavy waters of their emblematic organisation scope successful the North Pacific, their predominant occurrence successful the southwestern portion of the South China Sea suggests that our knowing of this colonisation remains importantly limited.”
He noted that there's inactive a batch much enactment to beryllium done to recognize the 'highly assertive behaviour of sharks observed'.
Tian said it 'suggests that this portion inactive harbors abundant nutrient sources successful the heavy sea. But what precisely are they?'
"This question is intriguing for some carnal organisation and behavioral research," helium added.
The probe was published successful the successful the diary Ocean-Land-Atmosphere Research connected 1 June, 2025.
