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.

The proximity of these strandings has reignited discussions about the oarfish's mythical reputation as a predictor of natural disasters.

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.
