Marine biologist Dr. Sarah Chen still remembers the moment she first saw a coelacanth in a museum as a child. “I pressed my nose against the glass case and thought someone was playing a joke,” she recalls. “This thing looked like a dragon that forgot how to be mythical.” That same sense of wonder hit her again last month when she watched grainy footage from French divers who had done something extraordinary.
They had captured the first clear video of a living coelacanth in Indonesian waters.
For most of us, fish are just fish. But this particular catch represents something far more profound than your average nature documentary moment. These French divers didn’t just film a rare species – they documented a living piece of Earth’s ancient history swimming in our modern oceans.
When Living Fossils Refuse to Stay Extinct
The coelacanth filming expedition off Sulawesi’s coast wasn’t supposed to be a history-making dive. The three-person team from Marseille had spent months preparing for what they expected might be another disappointing search for one of evolution’s most elusive survivors.

“We’ve been chasing rumors and fishermen’s stories for years,” explains marine photographer Laurent Ballesta, who led the expedition. “Every time someone claims they’ve seen a coelacanth in these waters, we investigate. Usually, it turns out to be a grouper or some other large fish.”
But this time was different. At 80 meters depth, their high-definition cameras captured something that scientists thought was impossible in this region. The footage shows a prehistoric-looking fish with thick, fleshy fins moving along a vertical rock wall like it’s walking underwater.
The coelacanth has earned its reputation as a “living fossil” for good reason. While most species evolved dramatically over millions of years, this ancient fish has remained virtually unchanged since the Devonian period, roughly 400 million years ago.
Think about that timeline for a moment. This fish was swimming around before trees existed on land, before dinosaurs, before mammals, before pretty much everything we recognize as modern life.
What Makes This Discovery So Groundbreaking
The significance of this coelacanth filming goes beyond just getting pretty underwater footage. Scientists have been studying these creatures since 1938, when the first living specimen was caught off South Africa’s coast. But most research has relied on dead specimens, sonar readings, and occasional brief sightings.
Here’s what makes this Indonesian footage so valuable to researchers:
- Natural behavior documentation: For the first time, scientists can observe how coelacanths move and behave in their natural deep-water habitat
- Population distribution: The discovery suggests coelacanth populations might be more widespread than previously thought
- Conservation insights: Understanding their habitat preferences helps protect critical underwater ecosystems
- Evolutionary research: Live footage provides clues about how these ancient fish have survived while similar species went extinct
“This footage is like finding a dinosaur walking through your backyard,” notes Dr. Michael Roberts, a paleontologist at the Natural History Museum. “We’re literally watching evolution in slow motion.”

Why This Matters for Ocean Conservation
The successful coelacanth filming in Indonesian waters has immediate implications for marine conservation efforts. These fish serve as indicator species – their presence suggests healthy deep-water ecosystems that support countless other marine life forms.
But here’s the concerning part: coelacanths are critically endangered. Scientists estimate fewer than 1,000 individuals remain worldwide. Each filmed encounter becomes crucial data for understanding how to protect these living relics.
“When you’re dealing with a species that has survived four mass extinction events, losing them on our watch would be particularly tragic,” explains marine conservationist Dr. Elena Rodriguez. “This footage gives us hope that there might be unknown populations we can still protect.”
The discovery also highlights the importance of protecting deep-water habitats that remain largely unexplored. These underwater environments face increasing threats from deep-sea mining, pollution, and climate change.
Local Indonesian fishing communities have reported occasional coelacanth sightings for decades, but their accounts were often dismissed by the scientific community. This filming validates traditional knowledge and emphasizes the importance of working with local populations for conservation efforts.
The French diving team plans to return to Indonesian waters for additional filming expeditions. They’re hoping to document coelacanth feeding behavior, social interactions, and reproduction – aspects of their biology that remain largely mysterious.
“Every second of footage we capture is precious,” Ballesta explains. “We’re not just making a documentary – we’re creating a scientific record of a species that bridges the gap between ancient and modern life.”
FAQs
What makes the coelacanth a “living fossil”?
The coelacanth has remained virtually unchanged for 400 million years, retaining primitive features like lobed fins and a unique joint in its skull that most fish lost long ago.
Why is filming coelacanths so difficult?
These fish live at extreme depths (150-700 meters) in dark waters, making them nearly impossible to locate and film without specialized deep-diving equipment and low-light cameras.
How many coelacanths are left in the wild?
Scientists estimate fewer than 1,000 individual coelacanths remain worldwide, making them critically endangered and extremely rare to encounter.
Where else have coelacanths been found?
Besides the new Indonesian location, coelacanths have been documented near the Comoros Islands and off the South African coast, with most specimens coming from these two regions.
What do coelacanths eat?
These ancient fish are opportunistic predators that feed on smaller fish, squid, and crustaceans, using their unique lobed fins to maneuver in rocky deep-water environments.
Could there be more unknown coelacanth populations?
This Indonesian discovery suggests other populations might exist in unexplored deep-water habitats around the world, giving scientists hope for the species’ survival.
