The fish died shortly afterward, but scientists did not establish why it surfaced; the claim that it sought sunlight is an internet interpretation, not confirmed fact.
The footage was moving because it showed an animal almost never encountered in daylight, apparently out of place and vulnerable. The scientific story is no less remarkable than the viral one, but it is more uncertain: researchers can document the fish, its species and its death without knowing what brought it upward.
Key takeaways
- The viral fish was a female humpback anglerfish, also called the black seadevil, scientifically identified as Melanocetus johnsonii.
- The fish was filmed alive near the surface about two kilometres off Tenerife on January 26, 2025, during a Condrik Tenerife pelagic-shark research campaign.
- Melanocetus johnsonii normally lives between 100 and 4,500 metres deep, with a maximum recorded total length of 18 centimetres according to NOAA’s 2018 reference.
- The fish died shortly after the sighting and was later preserved and identified in Tenerife.
- No authoritative source established that the fish deliberately surfaced to see sunlight, and no single cause for its unusual appearance was confirmed.
- The female’s glowing lure, or esca, is a real biological adaptation used to attract prey in the darkness of the deep sea.
What happened to the anglerfish that surfaced?
The viral anglerfish was a female black seadevil, or humpback anglerfish (Melanocetus johnsonii), filmed alive near the ocean surface approximately two kilometres off Tenerife on January 26, 2025. The encounter happened during a Condrik Tenerife campaign researching pelagic sharks, not during a planned anglerfish survey. The project account published by Bluewave Alliance documents the research context and sighting.
The encounter was extraordinary because this is a deep-water species. The fish appeared close enough to the surface to be filmed in daylight, far outside the environment in which a black seadevil is normally seen. Reports described the sighting as the first reported observation under these particular live, near-surface daylight conditions, rather than proof that no member of the species had ever approached shallow water.

The fish died shortly after the encounter. Specialists in Tenerife subsequently preserved and identified the specimen. A report in El País noted the contrast between the animal’s intimidating appearance and its small size, while a later Cadena SER report covered the preserved fish and the continuing uncertainty about why it reached the surface.
Why did the anglerfish come to the surface?
No authoritative source in the available research established why the black seadevil surfaced. Scientists and science-news reports mentioned several possibilities, including illness or another pathology, an upwelling current, escape from a predator, or an unknown factor. Those possibilities are not a confirmed diagnosis.
The popular explanation that the fish “just wanted to see the light” is an emotional social-media interpretation, not a documented motive. There is no evidence that the fish chose to rise in order to experience sunlight, understood the surface as a destination, or anticipated its death. The available scientific coverage of the Tenerife anglerfish likewise leaves the cause unresolved.
| Question | Confirmed account | Social-media account |
|---|---|---|
| What was observed? | A female Melanocetus johnsonii near the surface off Tenerife. | “She finally saw the light.” |
| Why was the sighting unusual? | The species normally lives hundreds to thousands of metres below the surface. | The fish was portrayed as a traveller escaping darkness. |
| Why did it surface? | No single cause was established; illness, currents, predation and other explanations remain possible. | The fish intentionally sought sunlight. |
| What happened next? | The fish died shortly afterward and was preserved for examination. | The death became a tragic character arc and internet memorial. |
| What is the evidence? | Video, a documented research encounter, specialist identification and news reporting. | Memes, reaction videos, fan art and anthropomorphic captions. |
How deep do black seadevil anglerfish live?
Melanocetus johnsonii is a small deep-sea fish adapted to life where sunlight does not reach. According to NOAA’s 2018 Survey Fishes reference, the species occurs from 100 to 4,500 metres, is most commonly found between 100 and 2,100 metres, and reaches a maximum total length of 18 centimetres.

The black seadevil’s oversized mouth, sharp teeth and dark body are striking adaptations, but the animal is not a giant sea monster. The Tenerife fish was small enough to fit in the palm of a hand.
What does the anglerfish’s glowing lure do?
The glowing structure above the female’s mouth is a bioluminescent lure called the esca. The lure helps attract prey in the deep sea, where visual signals are otherwise difficult to produce. Museum and research references associate the glow with symbiotic bioluminescent bacteria. The Natural History Museum of Los Angeles County’s anglerfish reference explains the lure’s role in the animal’s hunting strategy.
The lure is not a lamp used to guide the fish toward the surface. It is a specialised predatory tool: potential prey are drawn toward the apparent point of light and can then be seized by the anglerfish’s large jaws. The Woods Hole Oceanographic Institution’s overview of anglerfish provides additional context on the relationship between deep-sea anglerfish, bioluminescence and feeding.

Are female and male anglerfish different?
Female deep-sea anglerfish have the familiar lure and dramatic teeth; males are dramatically smaller and have a different reproductive role. The striking animal in the Tenerife video was a female. The unusual biology of deep-sea anglerfish means that the word “anglerfish” does not describe one uniform body plan or lifestyle across every species.

The Tenerife animal should also not be confused with shallow-water monkfish, frogfish or other fish that are commonly called anglerfish. The black seadevil is a deep-sea ceratioid anglerfish, and its small size, lure and reproductive biology belong to that specialised group. The Natural History Museum’s discussion of deep-sea anglerfish behaviour illustrates why unusual movement or posture should not automatically be turned into a human-like intention.
Why were people mourning the death of an anglerfish?
Social media converted a rare scientific sighting into a compact emotional story: a strange-looking animal emerged from darkness, appeared vulnerable at the surface, and died soon afterward. The combination of rarity, apparent helplessness and an instantly understandable “journey into the light” made the event unusually easy to narrate and share.
Coverage documented crying videos, memes, fan art and animated interpretations on TikTok, X and Instagram. Some posts used phrases such as “the anglerfish who swam to the surface and died,” “she finally saw the light” and “I’m crying over this anglerfish.” Cybernews quoted one representative reaction as “I’m wrecked.” The phrase describes a user’s emotional response, not a scientific conclusion; the Cybernews report on the reaction records that distinction.
The internet’s response is not evidence that the fish possessed a human-like plan. Anthropomorphism can make an unfamiliar animal memorable, but it can also replace uncertainty with an invented motive. The more accurate summary is that people mourned a real animal after assigning it a tragic story that the evidence does not establish.

A live adult black seadevil near the surface is an exceptionally unusual observation because researchers rarely see this species in its normal habitat. The specimen also allowed specialists to preserve and examine an animal that is difficult to study alive at depth.
Dr. William Ludt, Assistant Curator of Ichthyology at the Natural History Museum of Los Angeles County, described a rare anglerfish specimen in the museum’s coverage this way: “It’s one of only about 30 adult female specimens of this species, and having one washed up in this condition is extraordinary.” The quotation concerns a rare specimen generally and should not be read as a claim that the Tenerife fish was one of that exact group. The museum’s anglerfish reference supplies the relevant specimen context.

The sighting does not by itself prove pollution, climate change or an ecological collapse. Those claims would require separate evidence about the animal’s health, local ocean conditions, population trends and environmental exposure. The responsible conclusion is narrower: the Tenerife encounter was rare, the fish died soon afterward, and the reason for its appearance remained unresolved in the available reporting.
