Friday Squid Blogging
It's from last September, but it's the biggest giant squid news in years -- a live giant squid caught on camera:
In their efforts to photograph the huge cephalopod, Tsunemi Kubodera and Kyoichi Mori have been using a camera and depth recorder attached to a long-line, which they lower into the sea from their research vessel.
Below the camera, they suspend a weighted jig -- a set of ganged hooks to snag the squid -- along with a single Japanese common squid as bait and an odour lure consisting of chopped-up shrimps.
At 0915 local time on 30 September 2004, they struck lucky. At a depth close to 1km in waters off Japan's Ogasawara Islands, an 8m-long Architeuthis wrapped its long tentacles around the bait, snagging one of them on the jig.
Kubodera and Mori took more than 550 images of the giant squid as it made repeated attempts to detach itself.
The pictures show the squid spreading its arms, enveloping the long-line and swimming away in its efforts to struggle free.
Finally, four hours and 13 minutes after it was first snagged, the attached tentacle broke off, allowing the squid to escape. The researchers retrieved a 5.5m portion with the line.

"Bottom-trawling by fisheries is destroying squid egg masses on the seabed, Dr O'Shea claimed."
Ah, so it is safer for the squid to carry her eggs after all.
"That it has been hard for humans to figure out what they do is tribute to its effectiveness."
Or the ineffectiveness/inattentiveness of humans. "Hey, look, it's the moon."

No. Architeuthis has a very high concentration of ammonia in its tissues, so high it would likely burn your mucous membranes. It is completely inedible to humans -- although apprently not to whales.
Call it "security through toxicity", a well know scheme from the natural world!
"I'm sorry for having posted four identical comments yesterday. I had problems with my network and misinterpreted the delayed publication as some technical defect on my side.
"But you could have left one copy - Full censorship of my contribution was not appropriate... dicontent, yours"
Sorry. The idential comments were from different names, and the text didn't make sense to me. I figured it was a troll.
Please repost the comment.
