The deep sea has long been a source of mystery and fear for many, with only about five percent of the world’s oceans having been explored. For those who aren’t afraid of the sea, the idea of what’s lurking beneath the waves might still send a shiver down their spine. However, a recent video shared by OceanX has left viewers utterly terrified after showcasing a prehistoric creature in the deep sea: the bluntnose sixgill shark.

Deep Sea Fear: The Bluntnose Sixgill Shark
In the haunting footage, the first signs of the massive shark are subtle. The camera captures sand stirring up from the ocean floor, creating eerie clouds as a snake-like shape begins to emerge. As the creature gets closer, the full size of the shark is revealed, and it’s nothing short of enormous.
The bluntnose sixgill shark is an ancient species that pre-dates most dinosaurs. This deep-sea predator has been lurking in the shadows of the ocean for millions of years. As the shark swims past the window of the submarine, viewers are left in awe at its size and primal nature. Observers on the vessel react in disbelief, calling it a “monster” and joking about the creature’s immense size, which is “bigger than the submarine.”
The Jaw-Dropping Size of the Bluntnose Sixgill Shark
This species of shark can grow up to a staggering 20 feet in length and can weigh anywhere from 500 to 1,000 kilograms. The sheer size of the shark is enough to send chills down anyone’s spine. But what has many viewers most unsettled is the shark’s large, human-like eye. One user described the eye as “unsettling,” commenting that it would be enough to give them a “straight heart attack.” Its haunting stare is undoubtedly one of the most unnerving aspects of this creature, as it seems to look directly at the observers with a chilling intensity.

A Prehistoric Predator in the Depths
The bluntnose sixgill shark has long been a dominant predator in the deep-sea ecosystem. Its ancient lineage and adaptability make it an apex predator in the dark, isolated world beneath the waves. The footage shared by OceanX, captured in collaboration with the Cape Eleuthera Institute, reveals a species rarely seen by human eyes, making this encounter all the more significant. In the video’s description, it’s noted that a satellite tag was placed on the shark, marking a historic moment for deep-sea exploration.
A Glimpse Into the Unknown
The reaction from viewers is a mix of awe and fear, with many comparing the shark to something out of a science fiction movie. The sight of such an ancient, mysterious creature raises questions about what else might be lurking in the unexplored parts of our oceans. As one commenter put it, it’s “insane to think such creatures exist in such completely isolated parts of our planet,” leaving the possibility of even larger and more frightening creatures just beyond our reach.
Conclusion: What Lurks Beneath?
The bluntnose sixgill shark is a reminder of the mysteries that still lie deep within our oceans, and how little we know about the vast, unexplored parts of the sea. For those fascinated by the deep, the encounter shared by OceanX is a rare and chilling glimpse into a prehistoric world that still exists today. But for others, it’s enough to make them reconsider the idea of deep-sea diving.
As the ocean remains largely unexplored, one can only wonder what other terrifying creatures are out there, waiting to be discovered. Until then, we’ll have to be content with the unsettling footage of the bluntnose sixgill shark and the chilling reminder that some mysteries are best left undisturbed.
