(CNN)Fears of an incoming natural disaster in Japan are swirling online after sightings of a deep-water fish believed to be a harbinger of earthquakes and tsunamis.
On Friday, two oarfish were discovered after being caught in fishing nets off the northern prefecture of Toyama, bringing the total found this season to seven. Earlier this week, a 3.2-meter (10.5 foot) oarfish washed up on the shore of Toyama Bay, while a 4-meter (13 foot) long oarfish was tangled in a fishing net off the port of Imizu.
The elusive oarfish live between 200 and 1,000 meters
(650 to 3,200 feet) deep and are characterized by silvery skin and red fins.
