A living remnant of an ancient world, unseen until now
In the lightless depths of the Pacific Ocean, a creature whose lineage stretches back 125 million years has finally been witnessed alive in its true home. For the first time, researchers have captured footage of the goblin shark moving through the deep — not dying at the surface as all previous encounters had ended, but inhabiting the darkness where it belongs. Two sightings, one near Jarvis Island in 2019 and another at the Tonga Trench in 2024, have quietly redrawn the boundaries of what science believed possible for this ancient and solitary animal.
- Every prior encounter with a living goblin shark ended the same way — hauled to the surface on a fishing line, dying in the open air, never seen in the world it actually inhabits.
- Two Pacific expeditions, five years apart, captured the creature on camera at depths reaching nearly 2,000 metres — 700 metres deeper than any previously recorded goblin shark.
- The sightings place the species in the Central Pacific for the first time, shattering assumptions about its geographic range and raising urgent questions about what else remains unseen in the deep.
- Across more than 50 days of continuous deep-sea footage, the goblin shark appeared for barely 20 seconds — a fleeting glimpse that nonetheless rewrote the scientific record.
- With its range now confirmed as far broader, the goblin shark can finally be folded into regional conservation frameworks, giving this living fossil a measure of formal protection it never had before.
For the first time, scientists have watched a goblin shark alive in the place where it actually lives — not expiring on a ship's deck, but moving through the deep ocean darkness it has inhabited for nearly 125 million years. Every previous encounter with a living specimen had followed the same grim pattern: a fishing line, a haul to the surface, a death. No one had ever documented one in its natural habitat. Until now.
Two separate expeditions changed that. In 2019, the remotely operated vehicle Hercules captured footage of a goblin shark near a seamount northwest of Jarvis Island at 1,237 metres depth. Then in 2024, a baited camera system aboard the R/V Dagon recorded another sighting near the Tonga Trench at 1,997 metres — a depth 700 metres beyond anything previously known for the species. The second observation lasted just over 20 seconds, but it was enough to fundamentally alter the scientific picture.
Conducted by the Minderoo-UWA Deep-Sea Research Centre and the University of Hawaii, the research also expanded the species' known geographic range into the Central Pacific, a region where goblin sharks were not previously thought to exist. Before these sightings, the species was believed to inhabit only narrow coastal zones near the western United States, Australia, and Japan.
Professor Alan Jamieson noted that the creature's appearance — brief, rare, and at such unexpected depths — underscored how little is truly known about the deep ocean. Lead author Aaron Judah pointed to the conservation implications: with its range now confirmed as far broader, the goblin shark can be included in regional management frameworks and biodiversity protection lists. In a world where sunlight never reaches and pressure would crush most living things, an ancient lineage continues quietly on — and science has only just begun to find it.
For the first time, scientists have watched a goblin shark move through the darkness of the deep ocean alive—not gasping on a ship's deck, not dying in the air, but in the place where it actually lives. Two separate sightings, captured on camera in the Pacific, have fundamentally changed what we know about one of the ocean's most elusive creatures.
The goblin shark, Mitsukurina owstoni, belongs to a family of sharks that has existed for nearly 125 million years. It is the last of its kind, a living remnant of an ancient world, which is why scientists sometimes call it a living fossil. Until now, every observation of a living goblin shark came the same way: a fishing line would snag one, haul it to the surface, and the creature would die in the process. No one had ever documented one in its natural habitat, moving in the depths where it belongs.
That changed during two separate expeditions. In 2019, researchers aboard the remotely operated vehicle Hercules captured footage of a goblin shark near an unnamed seamount northwest of Jarvis Island, at a depth of 1,237 metres. Then, in 2024, during an expedition to the Tonga Trench aboard the R/V Dagon, a baited camera system recorded another sighting at 1,997 metres. The second observation was brief—just over 20 seconds of footage—but it revealed something striking: this shark was living 700 metres deeper than any goblin shark previously known to science.
The research, conducted by the Minderoo-UWA Deep-Sea Research Centre and the University of Hawaii and published in the Journal of Fish Biology, extends not only the depth range of the species but also its geographic reach. Before these sightings, goblin sharks were thought to inhabit only narrow coastal areas off the western United States, Australia, and Japan in the Pacific, with small populations in the Atlantic and Indian Oceans. Both new observations place the species in the Central Pacific, a region where it was not previously known to exist.
Professor Alan Jamieson, director of the Deep-Sea Research Centre, expressed the significance of the moment. He noted that seeing the creature alive was remarkable enough, but discovering it at such depths and in such a different location fundamentally changed the picture. During the 2024 expedition alone, researchers filmed more than 50 days of continuous footage across depths ranging from 800 to 10,800 metres. The goblin shark appeared for just a fraction of that time, underscoring how rare and elusive the species truly is.
Aaron Judah, lead author of the study and a researcher at the University of Hawaii's Deep-Sea Fish Ecology Lab, emphasized what these findings mean for conservation. With the geographic range now expanded, the goblin shark can be included in regional management frameworks and added to nations' biodiversity protection lists. The discovery also serves as a reminder of how much remains unknown about the ocean. At depths where sunlight never reaches and pressure would crush most creatures, entire species continue their lives largely unseen by human eyes. Each new sighting is a small window into a world that still holds countless mysteries.
Citas Notables
I never thought we'd see one alive. It's not only seeing it alive that was fascinating, but also the fact the Tonga Trench goblin shark was 700 metres deeper than previous known.— Professor Alan Jamieson, Director of Minderoo-UWA Deep-Sea Research Centre
New discoveries like this demonstrate that there is still so much to explore in our deep ocean home. Given the newly expanded geographic range of the goblin shark, this species can be included in regional management and a nation's biodiversity list.— Aaron Judah, lead author and researcher at University of Hawaii
La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that we finally saw one alive, rather than just studying the ones that were caught?
Because a dead fish on a ship's deck tells you almost nothing about how it actually lives. You see a corpse, not a creature. Seeing it move through the water, in the darkness where it evolved, changes everything—you understand its habitat, its behavior, its place in the ecosystem.
The footage was only 20 seconds long. How much can you really learn from that?
You'd think very little, but that's the point. In 50 days of filming, they captured 20 seconds of a goblin shark. That brevity is the data. It tells you how rare this animal is, how deep it goes, where it actually lives. One sighting would be luck. Two sightings in the same study is a pattern.
So these sharks were living 700 metres deeper than anyone thought. Does that change how we protect them?
Completely. If you don't know where a species lives, you can't protect it. Now that we know goblin sharks inhabit the Central Pacific at these depths, countries in that region can include them in their conservation plans. It's the difference between protecting a phantom and protecting something real.
What strikes you most about this discovery?
That it took until 2024 to see one alive in nature. We've had submarines, cameras, deep-sea technology for decades. And yet this creature—a living fossil, the last of its family—remained almost completely unknown to us. It reminds you how much of the ocean is still genuinely unexplored.
Do you think there are other species down there we haven't seen yet?
Almost certainly. The ocean at those depths is vast and dark. We've barely scratched the surface.
