Marine biologists have made an extraordinary discovery off the coast of Tenerife, where a rare deep-sea black devil anglerfish was observed in broad daylight for what might be the first time ever. This rare event has sparked global interest, as the black seadevil anglerfish typically resides in the ocean’s darkest depths.
Unexpected Encounter With the Deep Sea Black Devil Fish
While conducting a shark research expedition, a team from the NGO Condrik encountered the mysterious creature just two kilometers from Tenerife’s coast. Underwater photographer David Jara Boguñá first spotted the fish, recognizing it as an adult Melanocetus johnsonii, a species known for its bioluminescent lure and menacing teeth.
This deep-sea predator, often called the deep-sea black devil anglerfish, is typically found between 200 and 2,000 meters below the surface. Until now, observations were limited to submarine images, larvae, or dead specimens. Seeing a deep-sea anglerfish alive and near the surface is an event almost unheard of.
Why Did the Black Seadevil Anglerfish Appear Near the Surface?
Scientists remain uncertain about what caused this deep-sea anglerfish to rise from its natural habitat. Marine biologist Laia Valor, who was present during the discovery, shared her thoughts:
“There could be thousands of reasons why it was there. It’s an extremely rare and isolated sighting. While we can’t say it never happens, if it were more common, we would see it more frequently. This could very well be the first time it has ever been filmed in these conditions.”
One theory suggests that El Niño, a weather phenomenon known to disrupt ocean currents, might have influenced the fish’s unusual behavior. Reduced cold water upwelling could have forced some deep-sea creatures to venture closer to the surface.
What Happens Next?
Sadly, the black seadevil anglerfish was in poor condition and only survived a few hours after being found. After its death, researchers transferred the specimen to the Museum of Nature and Archaeology (MUNA) in Santa Cruz de Tenerife for further study.
This rare encounter offers marine scientists a unique opportunity to study the deep-sea black devil anglerfish up close. Researchers hope to gain new insights into its behavior, anatomy, and the impact of environmental changes on deep-sea life.
A Glimpse Into the Deep Sea’s Most Elusive Predator
The deep-sea black devil fish is one of the ocean’s most mysterious predators. Despite its terrifying appearance, this species uses bioluminescence rather than speed or strength to hunt. The glowing lure on its head, filled with bacteria that produce light, attracts unsuspecting prey straight into its large, sharp-toothed mouth. Though rarely seen, the black seadevil anglerfish remains an icon of the deep ocean’s eerie beauty. This recent sighting may help uncover more about the hidden world of deep-sea creatures. Proving once again that the ocean still holds many secrets waiting to be discovered.
