Well, I've never heard of a Giant Squid eating a human but I do know they killed a few. Its likely there are numerous deaths and attacks on fishermen and divers but most go unreported. Technically a Giant Squid has the capability to klil and devour a human. It is even rumored they could and have killed sperm wells but such cases have never been reported. Odds are we will never know if they can kill some of the largest animals in the see since whales sink when they die and rarely wash up on shores.
your dumb, and nothing you could ever do will make it go away
