Try to forget about this footage next time you go swimming.
It's incredibly rare to see a giant squid alive—and it's even rarer to see it cruising along next to your boat anchor.
The cephalopod was seen cruising Toyama Bay on Japan's west coast, an area already known for its stunning firefly squid, which glow an iridescent blue and gather in the area to spawn. This squid, however, was an entirely different beast.
Reports in Japanese say that the creature was filmed on December 24, seen by an underwater camera swimming near boat moorings. It was reportedly about 13 feet long and 3 feet around. Some on Twitter have suggested that the species may be Architeuthis, a deep-ocean dwelling creature that can grow up to 43 feet. Here's some more fascinating and insane footage of the species (try to forget it the next time you go swimming, though):
