Since January this year, several giant squids have been caught by fishermen along the Sea of Japan coast. This is viewed as an ominous sign of forthcoming earthquakes as these giant squids normally live in the deep depths of the ocean.

Here is a video of one of the giant squids caught:

Here is a list of the giant squids that have been caught so far:

Jan. 4th: one giant squid caught, 3 to 4-meters long.

Jan. 8th: one giant squid, 4-meters long (13 feet and 1 inch) without its longest tentacles, weighing 150 kg (330 lb.)

Jan. 21st: one giant squid, 8-meters long (26 feet and 3 inches)

Feb. 11th: one giant squid.

Feb. 25th: one giant squid, 9-meters long including the tentacles, weighing 200 kg (440 lb.)

One of the fishermen is quoted as saying, "I had seen no giant squid before in my 15-year fishing career. I wonder whether it may be some kind of omen."

Scientists think it is happening because the ocean is too cold this year and the invertebrate creatures are swimming to the more shallow sea for warmth. Giant squids usually live about 600 meters (almost 2,000 feet) below the water's surface where the temperatures are 6 to 10 degrees Celsius, according to Tsunemi Kubodera, the collection director at Japan's National Museum of Nature and Science. Kubodera speculates that the giant squids swam close to the surface for warmer water but were unable to stay buoyant and got swept toward the beach by winds. Nevertheless, people are advised to take precautionary measures.
