This is from the Guiness World Book
Largest Eye
The Atlantic giant squid (Architeuthis dux) has larger eyes than any other animal. A record-breaking specimen found in Thimble Tickle Bay, Newfoundland, Canada, in 1878, had eyes with an estimated diameter of 50 cm (20 in).
If this was from the older book I used to have, this animal was over 6 tons. They were not absolutly certain until a DNA sample was done years later and found it to be a squid.
For Octopi it was about 4700lbs.
In WWII they were found to be picking off sailors and pilots who were floating in the waters after ships and planes went down. A destroyer radar tech was monitoring the radar one day when the screen went blank. He watched and wondered what happened. He rechecked the instruments and then it suddenly came back on. When the ship docked in port he checked the front of the ship where the radar bra was and found what looked to be a tooth embeded in the bra. He pulled the massive tooth free and had it analyzed. It was found to be of a squid and it was estimated that the squid would have had to have been 200 foot in length.
I would imagine they only speak about these smaller ones as to not bring attention to the fact that the oceans are so overfished that they cannot support life they way it used to be only a short time ago.
