Everybody would agree to this fact that we know more about the extinct animals, dinosaurs, than still existing Giant Squids. But the stories of giant squids are popular since ages mostly told by the sailors. The first being, told by the Norwegian sailors, in twelfth century, who described the giant squid as Kraken from the word Krake, which meant twisted or unhealthy.

The French sailors, who claimed to have attacked by the Krakan, off the Canary Islands described it as a 36 feet long monster that created whirlpool that could actually sink ships and the tentacles big enough to reach even the tallest mast.

One of the most popular giant squid legends tell us about a 60-foot giant squid trying its best to grapple and virtually gobble up the entire crew of a ship as detailed by Jules Verne. While this story is technically not amongst the giant squid legends since Jules Verne's "20,000 Leagues Under the Sea" is categorized as entirely fictional, there are other giant squid legends that supposedly root from the ancient times where men used to travel through the open seas in the hopes of discovering new land. These ships used to encounter such giant squids that measure up to 100 feet long, but this basically makes up the entirety of such giant squid legends.
