The kraken (/ˈkrɑːkən/)[1] is a legendary cephalopod-like sea monster of giant size that is said to dwell off the coasts of Norway and Greenland. Authors over the years have postulated that the legend originated from sightings of giant squids that may grow to 13–15 meters (40–50 feet) in length. The sheer size and fearsome appearance attributed to the kraken have made it a common ocean-dwelling monster in various fictional works.
