Deep-sea: The ocean has always been full of mysteries, but every now and then, something happens that makes scientists, nature lovers, and even casual observers stop and wonder. Recently, such a moment unfolded when a rare black seadevil anglerfish—a creature that usually lives in the crushing darkness of the deep sea—was spotted swimming close to the surface of the Atlantic Ocean.
This extraordinary encounter took place off the coast of Tenerife near the Canary Islands, where marine life photographer David Jara Boguna and the Spanish NGO CondriK Tenerife were studying sharks. What they saw was something they never expected—a living black seadevil anglerfish gliding through the sunlit waves. According to The New York Times, this may be the first recorded sighting of a live adult black seadevil (Melanocetus johnsonii) in broad daylight, at the ocean’s surface.
A video of the fish, shared on Instagram, quickly caught the world’s attention. The caption called it “the first recorded sighting of a black demon alive, in daylight, and on the surface.” The female fish, whose Latin name literally means “black sea monster,” appeared surreal against the bright ocean backdrop. Sadly, the creature died soon after the footage was captured, making the sighting even more precious and rare.
Why was this deep-sea predator so far from home? Experts aren’t certain. The black seadevil usually dwells between 650 and 6,500 feet beneath the waves, in an environment with no sunlight and immense pressure. Theories suggest the fish may have been sick or escaping a predator. In deep-sea folklore, such rare surface appearances have sometimes been linked to upcoming natural disasters, though science has yet to confirm any direct connection.
Life in the deep sea is unlike anything at the surface. The darkness is absolute, the pressure immense, and food scarce. To survive, many species have evolved extraordinary features—like bioluminescence to attract prey, enormous jaws, and needle-sharp teeth to capture anything edible. The black seadevil’s bizarre appearance is simply an adaptation to one of the harshest environments on Earth. As Ben Frable, senior collection manager of marine vertebrates at the Scripps Institution of Oceanography, explains: “The deep sea is a very different environment from surface waters. The organisms there are highly adapted and appear very different to us.”
This sighting is more than just a strange event—it’s a reminder of how little we know about the oceans. It offers scientists a rare opportunity to study a creature that spends its life in a world far beyond human reach, and it leaves us with the same feeling the deep sea always inspires: awe, curiosity, and a touch of unease.
