The story found its way into the archives of the National Geographic, who has opened up the mystery to the public. ("Seeing" as how the Squid experts were busy doing more important things...) Guesses range from Squid to Swordfish to Tuna to Aliens. DNA testing will answer many of these questions as results come in.
Seriously though... what the hell could be so much more important for a Giant Squid Expert?! That seems to me to be the real mystery/conspiracy here. Silly Squid experts...
