A dead oarfish spotted along the Southern California coast marks the state's third sighting of the so-called "doomsday fish" this year.

The doomsday fish got its name because it looks like a mythical sea creature, with a long, ribbon-shaped body that can grow up to 30 feet.

A rare deep-sea oarfish has washed up in California, the third to do so in a few months and only the 22nd since 1901.
