I think this is a mistranslation. Lots of giant squid have washed up over the past hundred years or so. A really big one in Australia like a couple of months ago. I think they mean a giant octopus like the one that washed up in Florida.
I think I remember seeing a special on giant squids on the discovery channel. They had a bunch of bodies to show that there have been quite a few, and they showed how real they are. (I don't know about others, but I didn't really know giant squids existed or at least not that many.) They did say that they had never seen one alive, though, and they pretty much had to guess on how they lived.
actually, we know (supposedly) more about the surface of the moon than we do about the ocean floor (deep regions). probably true.
