Pacific Sleeper Sharks Spotted in South China Sea—A Deep-Sea Discovery Like No Other

So get this—scientists recently dropped a cow carcass over 1.6 kilometers deep into the South China Sea, not knowing what exactly they’d attract. What they caught on camera next has completely stunned the marine science world. Emerging from the inky black depths was a massive Pacific sleeper shark—an animal that’s never before been recorded in this part of the world. And this wasn’t just one lucky glimpse. The cameras revealed multiple sleeper sharks arriving, feeding, and showing off behaviors we've never seen so clearly before.

Now normally, Pacific sleeper sharks are cold-water dwellers. You'd find them lurking in the frigid environments of the North Pacific—around places like the Bering Sea, the Gulf of Alaska, and near Baja California. So seeing them all the way down in the tropical South China Sea? That’s huge. It means their known range just expanded dramatically. Scientists are now questioning what else we might be missing about these elusive giants of the deep.

The research team, led by Sun Yat-sen University and the Southern Marine Science and Engineering Guangdong Laboratory, was actually conducting a study on how large deep-sea animals feed. They chose a rather bold method: drop a whole cow carcass to the seafloor southeast of Hainan Island and monitor what happens. And what they captured is beyond fascinating.

What’s especially intriguing is how these sharks behaved during feeding. The bigger ones—some over 2.7 meters long—charged in to tear chunks off the carcass with brutal force. But the smaller ones? They hung back, circling, seemingly waiting their turn. The footage actually showed a kind of “queuing” system, where sharks arriving from behind took priority over those already feeding. That’s not something we typically associate with shark behavior. It suggests these animals may have a social or hierarchical structure even in the deep sea.

And here's another weird detail—every shark they recorded was female. That could be coincidence, but it might also point to the South China Sea acting as a kind of nursery for large shark species, similar to patterns seen with megamouth sharks in the area. If that’s true, this part of the ocean could be playing a critical, previously unknown role in shark conservation and biology.

One more thing that stood out? These sharks don’t have the protective eye membranes that many predators do. So what do they do when things get violent during feeding? They retract their eyes into their heads. Researchers believe this is a defense mechanism—a way to shield one of their most vulnerable parts while tearing into prey.

And all of this—every bite, every cautious circle, every eye twitch—was captured because a team of scientists dared to ask: what would happen if we dropped a cow into the abyss?

This groundbreaking footage doesn’t just show sharks feeding. It opens up new questions about species distribution, behavior, deep-sea ecosystems, and maybe even how much we’ve underestimated the life teeming in the dark. The South China Sea, it seems, has more secrets left to tell.
