A number of giant squids have been caught along the coast of the Sea of Japan this year, raising concerns among fishermen that it might represent some kind of "omen."

The giant squid, classified as Architeuthis, is the largest invertebrate.

One giant squid was taken to Himi fishing port in Toyama Prefecture on Jan. 4. Another was found in a stationary net off Sado Island in Niigata Prefecture on Jan. 8.
