A rare and almost mythical creature from the deep sea has washed up on a California beach in the form of an oarfish measuring more than 9 feet long!

As for why people consider the oarfish to be a “doomsday” fish, NBC News explains that — as oarfish typically dwell in the deep ocean — the appearance of one suggests a coming natural disaster like an earthquake. About 20, for example, washed up prior to an earthquake in Japan in 2011, the country’s worst on record.

A rare deep sea fish, regarded as a harbinger of doom, has washed up on a southern California shore. The Scripps Institution of Oceanography at the University of California, San Diego, said one of its PhD students discovered an oarfish on a beach in Encinitas last week that was around nine to ten feet long.
