Rare footage of Squid off Coast of Japan

This is amazing!
Yes it is, thanks @Right Now !

I would really like to see a giant squid in the wild, but don't suppose I ever will.

I saw a school of maybe a dozen once whilst snorkeling in the British Virgin Islands. They were swimming in shallow water and almost instantly changed color to match the bottom just below... Not too fast so I was able to follow for a little while. Quite memorable.
Good to eat and good to use as bait.
Yep, done lots of both!
