In the depths of the ocean, creatures of nightmarish proportions lurk, rarely seen by human eyes. Recently, one such denizen of the deep made an unprecedented appearance at the surface, sending shockwaves through the marine biology community. The Johnson’s abyssal anglerfish, aptly nicknamed the “black devil of the abyss,” was spotted off the coast of Tenerife, Spain, in a sighting that has both thrilled and terrified observers.
Unexpected visitor from the deep
On January 26, 2025, members of the NGO Condrik Tenerife were in for the shock of their lives when they encountered a living Johnson’s abyssal anglerfish near the surface waters off Guía de Isora, a municipality on the western coast of Tenerife. This extraordinary event marks what experts believe to be the first-ever observation of a live “black devil” during daylight hours at the ocean’s surface.
Typically dwelling at depths between 200 and 2000 meters, these elusive creatures are adapted to the crushing pressures and eternal darkness of the abyssal zone. Their sudden appearance in shallow waters has puzzled scientists and raised questions about the changing dynamics of our oceans. Much like the unpredictable nature of underwater volcanoes, the emergence of deep-sea life at the surface is a reminder of the ocean’s mysterious and ever-changing nature.
The footage captured by Condrik Tenerife shows the anglerfish engaged in a vertical swim, seemingly disoriented and out of its element. This behavior is highly unusual for a species that typically ambushes its prey in the lightless depths. Marine biologists are now scrambling to understand what could have driven this abyssal resident to ascend to such unfamiliar territory.
Anatomy of a deep-sea predator
The Johnson’s abyssal anglerfish is a marvel of evolutionary adaptation, its form honed by millions of years in the unforgiving deep. Its jet-black coloration serves as perfect camouflage in the lightless abyss, while its disproportionately large mouth is lined with needle-sharp teeth, capable of engulfing prey larger than itself.
Perhaps the most distinctive feature of this otherworldly creature is the bioluminescent lure that dangles from its forehead. This natural fishing rod, known as an esca, emits a soft glow that attracts unsuspecting prey in the pitch-black environment of the deep sea. The anglerfish’s ability to produce light in the darkness is a fascinating example of bioluminescence, a phenomenon that continues to captivate scientists and nature enthusiasts alike.
The recent sighting has allowed researchers to observe these features on a live specimen outside of its natural habitat, providing invaluable insights into the physiology and behavior of this elusive species. Much like rescued animals finding new homes, this anglerfish’s journey to the surface has opened up new avenues for scientific study and public fascination with deep-sea life.

Theories behind the surface sighting
The unexpected appearance of the Johnson’s abyssal anglerfish at the ocean’s surface has sparked intense speculation among marine biologists. Several theories have been proposed to explain this rare event, each shedding light on the complex ecosystems of the deep sea and the challenges faced by its inhabitants.
One hypothesis suggests that the fish may have been disoriented by a powerful upwelling current, forcibly carrying it from its abyssal home to the surface waters. These vertical movements of water can transport nutrients and organisms across vast distances, potentially explaining the anglerfish’s dramatic ascent.
Another possibility is that the creature was fleeing from a predator, driven to unfamiliar territory in a desperate bid for survival. The deep sea, while often thought of as a barren wasteland, is home to a complex food web where even apex predators must remain vigilant. The anglerfish’s journey to the surface might be a testament to the intense pressures of life in the abyss.
Some experts have also speculated that the fish may have been suffering from a illness or injury that impaired its ability to regulate its buoyancy. Much like abandoned animals finding new hope, this anglerfish’s appearance at the surface could be seen as a last-ditch effort for survival in an alien environment.
Implications for marine research and conservation
The sighting of the Johnson’s abyssal anglerfish at the surface is more than just a curiosity; it represents a unique opportunity for scientific advancement and raises important questions about the health of our oceans. Researchers are now analyzing the video footage and the circumstances surrounding the event to glean new insights into deep-sea ecology and the potential impacts of climate change on abyssal ecosystems.
This rare encounter underscores the importance of continued exploration and study of the deep sea. Despite advances in technology, much of the ocean’s depths remain unexplored, with new species and phenomena waiting to be discovered. The anglerfish’s appearance serves as a reminder of how much we have yet to learn about the vast underwater world that covers much of our planet.
Conservation efforts may also be influenced by this event. As surface waters warm due to climate change, deep-sea creatures may be forced to adapt or seek out new habitats. The plight of the Johnson’s abyssal anglerfish highlights the interconnectedness of marine ecosystems and the potential for disruptions in one area to have far-reaching consequences.
Moreover, this sighting emphasizes the need for responsible ocean exploration and management. As unexpected discoveries can occur during everyday activities, it’s crucial that we approach our interactions with marine life with care and respect, ensuring that our curiosity doesn’t come at the cost of these fragile ecosystems.

Legacy of the black devil’s surface debut
The Johnson’s abyssal anglerfish’s brief foray into the world above has left an indelible mark on marine science and public imagination. While the creature unfortunately did not survive long after its surface appearance, its body has been preserved for further study at the Museum of Nature and Archaeology in Santa Cruz de Tenerife.
This extraordinary event has reignited interest in deep-sea exploration and the bizarre life forms that inhabit the ocean’s darkest recesses. It serves as a powerful reminder of the wonders that still await discovery in the least explored regions of our planet.
As we continue to push the boundaries of ocean research, sightings like this one of the “black devil of the abyss” inspire both awe and a sense of responsibility. They challenge us to look deeper, to question our understanding of marine ecosystems, and to work towards preserving the delicate balance of life in our oceans for generations to come.
