For the second time this year, a rare deep-sea oarfish has washed ashore in San Diego County, giving scientists a chance to study the species without plumbing the depths of the ocean, it was announced Wednesday.
Last week, Scripps Institution of Oceanography PhD candidate Alison Laferriere found the deceased 9.5-foot (2.89m) specimen at Grandview Beach in Encinitas — just the 21st of its species documented to have washed up on California beaches since 1901, officials said.
A 12.25-foot (3.73m) long fish was found in August by kayakers and snorkelers in La Jolla Cove.

Ben Frable, manager of the Scripps Oceanography Marine Vertebrate Collection — one of the largest collections of deep-sea fish in the world — contacted the NOAA Fisheries West Coast team to recover the specimen and transport it to the Southwest Fisheries Science Centre, according to a Scripps statement.
“We took samples and froze the specimen awaiting further study and final preservation in the Marine Vertebrate Collection,” Frable said.
“Like with the previous oarfish, this specimen and the samples taken from it will be able to tell us much about the biology, anatomy, genomics and life history of oarfishes.”
It is unclear why two of the rarely seen, short-crested oarfish have washed up on local shores, Frable said.
“It may have to do with changes in ocean conditions and increased numbers of oarfish off our coast,” Frable said.
“Many researchers have suggested this as to why deep-water fish strand on beaches.
“Sometimes it may be linked to broader shifts, such as the El Niño and La Niña cycle, but this is not always the case. There was a weak El Niño earlier this year. This wash-up coincided with the recent red tide and Santa Ana winds last week but many variables could lead to these strandings.”
The species has a long, scale-less, ribbon-like silvery body with dark spots. A long red dorsal fin crest extends from the top of the head.
Oarfish have a mythical reputation as predictors of natural disasters and earthquakes, though there have been no sizable quakes recently in the San Diego area.
Also known as “sea serpents” or “doomsday fish,” oarfish occupy a hallowed place in the museum of marine oddities: They can grow to dozens of feet in length, are the longest bony fish in the world and generally swim vertically, according to Frable.
“They get at least 25 feet (7.62m), with reports in the 30-plus range,” Frable said.
“In terms of weight, it’s estimated the big ones are 500-plus pounds (226.8kg).”
If someone finds an unusual or rare creature on the beach, they are encouraged to alert the local lifeguards.
