The legendary “doom fish” has returned to California.
A long, ribbon-shaped oarfish, rarely seen and believed to signal disaster, has washed up on California’s shores for the second time this year.
PhD candidate Alison Laferriere from the Scripps Institution of Oceanography at UC San Diego discovered the nearly 10-foot-long oarfish on a beach in Encinitas, in southern California, last week.
Oarfish are elusive creatures that dwell in the deep ocean — often as far as 3,300 feet below the surface — in the mesopelagic zone, a dark region beyond the reach of sunlight.
These mysterious fish, which can grow up to 20 feet long, remain largely unstudied by scientists, according to the National Oceanic and Atmospheric Administration.
Rare, monstrously-proportioned and strangely-shaped, oarfish have sparked myths and legends for centuries and are sometimes referred to as the “doomsday fish” due to their reputation as predictors of natural disasters or earthquakes.
In 2011, the largely forgotten “earthquake fish” legend resurfaced after 20 oarfish washed ashore in the months leading up to Japan’s most powerful recorded earthquake.
The devastating tsunami that struck Japan on March 11, 2011, killed more than 15,000 people and was triggered by a 9.0-magnitude earthquake that gave the sea floor a massive shove toward Honshu, Japan’s largest island.
According to the Scripps Institution of Oceanography at UC San Diego, oarfish are incredibly rare.
Since 1901, only 21 oarfish have been documented washing up on California shores, according to the institution.
Ben Frable, a researcher at Scripps Institution of Oceanography, suggested that shifts in ocean conditions, along with a potential increase in oarfish populations, may be behind the uptick in sightings, he said in a statement this August.
This year’s previous oarfish, which measured 12 feet long, was spotted this summer by kayakers and snorkelers in La Jolla Cove, north of downtown San Diego. The fish was later transported to the NOAA’s Fisheries Science Center in La Jolla for further study.
“Rare encounters like this offer an incredible opportunity to learn more about this species and its behavior,” said Frable.
Frable also noted in a statement that while scientists are still unsure of the exact causes, La Jolla’s shores, which is near two underwater canyons that funnel deep water up to shore, tends to be a hotspot for disoriented or injured deep-sea fish to wash up.
As scientists continue to study these rare appearances, the mysterious oarfish is sparking curiosity and intrigue.
A 2019 study by researchers in Japan, found no solid scientific evidence linking oarfish to earthquakes — leaving the doom they may or may not portend open to anyone’s guess.
