Mysterious 'doomsday fish' washes up on California beach
Listen to article
A rare oarfish, long associated with myths of impending disaster, has washed up on a California beach for the second time this year.
The nearly 10-foot-long creature was discovered last week on a beach in Encinitas, southern California, by Alison Laferriere, a PhD candidate at the Scripps Institution of Oceanography at UC San Diego.
Oarfish, which can grow up to 20 feet long, are elusive deep-sea creatures that typically live in the mesopelagic zone, about 3,300 feet below the ocean surface, where light cannot reach.
These ribbon-shaped fish, with their serpentine bodies, are rarely seen by humans, and as a result, have been steeped in legend for centuries.
Often referred to as the "doomsday fish," oarfish have long been associated with mythical predictions of natural disasters, particularly earthquakes.
The legend gained widespread attention in 2011, when 20 oarfish washed ashore in Japan in the months leading up to the devastating 9.0-magnitude earthquake and tsunami that struck the country.
The proximity of these strandings to the earthquake gave rise to the belief that the appearance of oarfish might signal impending seismic activity.
However, scientists remain sceptical of any direct link between oarfish and natural disasters. The Scripps Institution of Oceanography, where Alison Laferriere works, noted that oarfish sightings in California are extremely rare.
Since 1901, only 21 oarfish have been documented washing up on the state's shores. This most recent sighting is the second in 2024, following the discovery of a 12-foot-long oarfish found dead in the water off San Diego in August.
The increase in sightings has led to speculation about changing ocean conditions. Ben Frable, a fish expert with the Scripps Institution, suggested that broader shifts in the environment—such as El Niño or La Niña patterns—could be behind the increase in oarfish strandings, although it is unclear whether these changes are directly responsible. These oceanic fluctuations affect water temperature, currents, and other factors that may influence marine life.
Oarfish are typically very deep-water creatures, far removed from coastal ecosystems, which makes their appearances in shallow waters all the more mysterious. "Oarfish are incredibly rare. Their deep-sea habitat makes them difficult to study, and sightings are a huge event," Ben Frable explained in a statement.
When Alison Laferriere and her colleagues at Scripps found the washed-up oarfish, they collected samples for further analysis. An autopsy was conducted to study the fish's internal organs, providing valuable data for marine biologists.
The fish will also be preserved for further study in the institution's marine vertebrate collection. In fact, the researchers plan to use the recovered specimen to generate the 'first high-quality, chromosome-level genome' for the species, which has been largely understudied by scientists.
Despite their ominous reputation, oarfish are harmless creatures that feed on plankton, small fish, and squid in the deep ocean. The fish's large size and elongated body shape, however, have often been interpreted in folklore as signs of disaster. Beyond their connection to earthquake myths, oarfish continue to capture the imagination of both scientists and the general public.
Ben Frable and other researchers caution against jumping to conclusions based on the fish's appearance. While the strandings of oarfish may seem to coincide with seismic events, there is no direct evidence to suggest that their appearance signals an impending disaster. Rather, the strandings may be linked to broader ecological factors, such as shifts in the ocean environment, that impact deep-sea species.
As the mystery of the oarfish continues to intrigue, researchers remain focused on studying this elusive species. The ongoing research aims to better understand the oarfish's biology and its role in the deep-sea ecosystem, while also examining the possible links between climate change, ocean conditions, and these rare strandings.
For now, the appearance of oarfish on California's shores remains a rare and fascinating event, drawing attention both for its scientific value and its continued place in myth.

Clownfish shrink during marine heat wave to survive, scientists say
Listen to article Some clownfish off the coast of Papua New Guinea shrank their bodies during a marine heat wave — and the smaller fish were more likely to survive, according to a new study. Scientists tracked 134 clownfish in Kimbe Bay during a record marine heat wave in 2023 that continues to bleach coral reefs around the world. Of those, 101 were observed to have temporarily shrunk in length, researchers reported. 'We were really shocked at first when we saw that they were shrinking at all,' said Morgan Bennett-Smith of Boston University, one of the study's authors. The findings, published Wednesday in Science Advances, shed new light on how coral reef fish are adapting to more frequent and intense marine heat waves linked to climate change. The researchers suspect the clownfish may reabsorb bone matter to reduce their size. Shrinking could help conserve energy, as smaller bodies require less food to survive in high-stress environments. In some cases, clownfish pairs appeared to synchronise their shrinking. Female fish remained larger than males, preserving the species' female-dominated social structure even as both fish lost size. 'Certain pairs adjusted together to maintain hierarchy — it's fascinating,' said study co-author Melissa Versteeg from Newcastle University. While temporary size reduction is known in other animals — such as marine iguanas during El Niño events — this is the first time scientists have documented the behaviour in coral reef fish. 'This is another tool in the toolbox that fish are going to use to deal with a changing world,' said Simon Thorrold, an ocean ecologist at Woods Hole Oceanographic Institution, who was not involved in the research. Importantly, the scientists observed that the clownfish grew back to normal size once conditions improved, suggesting a temporary coping mechanism rather than a permanent shift. 'These natural systems really are under stress, but there's a capacity for incredible resilience,' Versteeg said. Researchers caution, however, that it's not yet clear whether the fish can continue to shrink and regrow if marine heat waves persist or become more severe.

'Doomsday' fish washes up in Canary Islands, sparking fears of disaster
Listen to article A rare oarfish, often associated with myths predicting natural disasters, has washed up on a beach in the Canary Islands, prompting concern among locals and online commentators. The deep-sea creature was discovered by beachgoers at Playa Quemada, with footage of the incident quickly going viral. The video, shows a man in swim shorts approaching the silver fish with its striking translucent orange fins in an attempt to rescue it. In Japanese mythology, the oarfish is known as Ryūgū no tsukai—or "messenger of the Sea God"—and has long been considered an omen of catastrophic events such as earthquakes, tsunamis, and hurricanes. Photo: The sea creature was discovered by bathers Jam Press/Greg Hayes Its presence near the surface is rare, as the species typically inhabits deep ocean waters, making it difficult to study. The sighting has fueled speculation online, with social media users expressing alarm. One commenter wrote, "Something bad is going to happen," while another stated, "They show up before natural disasters." Others urged people to return the fish to the sea, fearing its presence could signal an impending seismic event. Last time a rare oarfish, long associated with myths of impending disaster, had washed up on a California beach for the second time since November 2024. The nearly 10-foot-long creature was discovered last week on a beach in Encinitas, Southern California, by Alison Laferriere, a PhD candidate at the Scripps Institution of Oceanography at UC San Diego.

2025 sets record for hottest January ever
Listen to article The World Meteorological Organization (WMO) announced on Thursday that January 2025 was the hottest January ever recorded, according to data analyzed by the UN's Copernicus Climate Service. The month saw temperatures 1.75°C above pre-industrial levels and 0.79°C higher than the 1991-2020 average, defying expectations that the La Niña weather phenomenon would bring cooler temperatures. In 2015, the international community agreed to limit global temperature rise to 1.5°C above pre-industrial levels. Despite this, January's data came as a surprise to climate experts at Copernicus, who noted it marked the 18th month in the last 19 with global-average surface temperatures more than 1.5°C above pre-industrial levels. Samantha Burgess, Copernicus Strategic Lead for Climate, described January 2025's temperatures as 'surprising,' continuing the record-high trend observed over the past two years, despite the development of La Niña conditions, which typically have a temporary cooling effect. In terms of regional weather patterns, January 2025 will be remembered for "wetter-than-average conditions" in western Europe, parts of Italy, Scandinavia, and the Baltic countries, with heavy precipitation and flooding in some areas. Meanwhile, drier-than-average conditions were observed in northern UK and Ireland, eastern Spain, and areas north of the Black Sea. Globally, wetter-than-average conditions were reported in Alaska, Canada, central and eastern Russia, eastern Australia, southeastern Africa, and southern Brazil, with floods causing significant damage. Conversely, the southwestern United States, northern Mexico, northern Africa, the Middle East, Central Asia, eastern China, and much of southern Africa, South America, and Australia experienced drier-than-average weather. The rise in global temperatures is largely attributed to human activities, particularly the burning of fossil fuels, which has led to record levels of greenhouse gases in the atmosphere. Deforestation and other factors also contribute to the ongoing temperature rise.
