According to Japanese folklore, there is a rare species of deep-water fish that can predict earthquakes. Legend has it that whenever an earthquake or tsunami is about to strike, the so-called "doomsday fish" will make the journey up from the depths of the ocean to warn the nearby humans.
As a general rule, it is very rare to spot a doomsday fish in shallow waters. In the past few years, however, that has started to change.
