Giant Squid Caught on Film

caffeined writes "I think almost every geek's heart must skip a beat when they hear about giant squids (think "Jules Verne"). It appears the two Japanese researchers have managed (for the first time) to get actual footage of a live giant squid in action. It was "only" 26 feet long (a little more than 8m) which is big enough for me." Update: Pictures and no registration required at National Geographic.

How long?

[the-amazing-blob]

How long until we start catching them and getting them in aquariums?

Re:How long?

[mrchaotica]

Aren't giant squids one of those animals that lives so deep that it can't survive without really high pressure (too high for an aquarium)?

According to Wikipedia, giant squids don't have swim bladders. Instead, they use ammonia in some way or another.

Actually, yes, for awhile. The primary problem is that we have too many moist mucous membranes that will loose fluid. A face mask, covering ones nose and mouth would let one stay alive in space, even without a suit. However, one's eardrums would burst and one's eyes would boil away and probably burst as well. Add pain to the mixture as you think appropriate.

Arguably, one could make a space suit that was simply a skin tight layer + helmet. The problem with that would be that it would have to be *perfectly* skin tight. I.e. Any gas between the suit and you, and you will be VERY uncomfortable, as the gas makes the suit expand like a balloon. Assuming that was worked out, it would have of number advantages over conventional space suits. The joints would be MUCH more flexible, and less complex, as they wouldn't require complicated pressure equalization systems to allow the joints to move.

Hey, I just thought out how to get around the skintight issue. Cover the human in vaseline, or some other viscous nonvolatile (which means the vaseline wouldn't work very long, depending how much was evaporating through the suit) fluid, to fill in all the empty spaces left by the suit!

So you get a system that is = person + skin tight body suit + nonvolatile fluid + bubble helmet + Air supply. I'm certain it would work, just not sure for how long. The limiting factor is how fast you lose volatiles, but it could easily be made to work as long as the longest spacewalks the US has ever attempted, and would be a hell of a lot lighter, simpler, and cheaper.

Pressure is a BIG issue. Chemistry changes at pressure, reactions go differently.

Divers going below about 90 feet (30 metres) breathing air suffer nitrogen narcosis as dissolved nitrogen in the nerves cause an effect akin to drunkenness or partial anaesthesia.

Because the human breathing response is driven by the absolute partial pressure of carbon dioxide in the bloodstream, not its ratio to oxygen, deep diving means breathing much more air than is needed simply to flush out the apparent elevated level of co2 in the blood - the physiology is tricked by the pressure. Anyone practising emergency surfacing from a deep dive is astonished that they don't need to breath as they rise - you continuously exhale as the gas in the lungs expands (I was taught to sing on the way up) and the breathing response isn't triggered because the detected co2 level keeps falling.

Now this may not affect squid much, it's hard to believe that there are no pressure effects on the chemistry underpinning their biology.

That's not the primary problem. The primary problem is that the human brain needs a minimum level of oxygen to operate; that oxygen can only be provided by the respitory system at a rate directly proportional to the o2 pressure in the respirated environment(or "partial pressure" in mixed gas environments, like earth at sealevel). If you decrease pressure, you must likewise increase o2 or risk cognitive failure and rapid blackout (with little-to-no warning either). Now, as with all biology, individuals differ widely, but .... even in a pure o2 environment (which certainly is already required for EVA), anything below about 3psi is dangerous. Lungs are a nice flexible organ, but they aren't capable of withstanding more than a very slight pressure differential without over-expansion and potential embolism occuring.

That means that any environmental suit must maintain the same approximate force upon the wearer as exerted by the wearer's respiration gas pressure. Likewise, in order to prevent circulatory damage, the force needs to be exerted pretty evenly across the entire body. So, in effect, you're talking about a suit that can "squeeze" the wearer evenly at a minimum of three or so lbs/sq inch. Assuming such could be designed, how do you propose one would don such an outfit in a pressurised environment? I don't care how great your lubricant of choice is, I can't imagine someone getting into one of these things in the first place without great physical harm occuring.

"The fact that the average temperature of all space is 4' kelvin is also an issue. "

Nope. In the void there is no convection -- and that's how you lose most heat. In space you only lose it through thermal radiation.

Re:How long?

[moonbender]

It doesn't sound like it's fun, though: "At NASA's Manned Spacecraft Center (now renamed Johnson Space Center) we had a test subject accidentally exposed to a near vacuum (less than 1 psi) in an incident involving a leaking space suit in a vacuum chamber back in '65. He remained conscious for about 14 seconds, which is about the time it takes for O2 deprived blood to go from the lungs to the brain. The suit probably did not reach a hard vacuum, and we began repressurizing the chamber within 15 seconds. The subject regained consciousness at around 15,000 feet equivalent altitude. The subject later reported that he could feel and hear the air leaking out, and his last conscious memory was of the water on his tongue beginning to boil."

Thanks for the link.

Titanic Struggle

[Quirk]

My step Dad, a naval officer (pilot), now retired, saw a whale surface with a giant squid engulfing it's head. The whale breached a couple of times with the giant squid unrelentingly attached, attacking and maybe feeding.

I've read that during WWII giant squid would attack red life boats filled with sailors from sunk ships. Apparently the red colour attracts them.

By all accounts they are extremely aggresive, suggesting they don't see themselves as prey and know no predators.

I think I'll keep my exposure to them second hand.

Re:Titanic Struggle

[Wazukkithemaster]

From my immense pool of knowledgem gathered mostly from years of watching the discovery channel, i have learned that giant squid would not be able to survive at the surface of the ocean. their blood is EXTREMELY thin and thus easily influenced by their surrounding environment. Furthermore, their blood temperature must stay around 10 degrees Celcius and too much variation would cause death. Also, The water pressure that they are used to be subject to is much greater in the depths of the ocean (obviously) than at its surface. That said, its unlikely the stories of giant squid feeding on red lifeboats filled with sailors (and what-not) are unlikely, as for the whale... i'm not sure

Now that you mention sperm whales..

[Spy der Mann]

http://en.wikipedia.org/wiki/Sperm_Whale

There was an episode on Discovery's Animal Face-off about a Giant Squid versus a Sperm Whale: The winner was the sperm whale, which stunned the squid with its sonic emitter, and then ate it whole. Of course, before this, the whale had to swim at a very high speed to get rid of the squid's clawed tentacles (this is why some sperm whales have scars on their heads, because you can't just take off a squid's tentacle, you have to rip it off - ouch).

It was an exciting and interesting episode :)

Re:WOW.

[Ironsides]

though I can't imagine there's too many predators that want to tangle with a 40 foot long tentacle monster.

It only takes one, and the squid is dead. That one happens to be sperm whales, maybe other giant squid as well. Possibly even some other large predators we have never found as of yet (or think are extinct).

did you know...

[Kadmos]

Given the ability of squid to join together with other "squids" the potential for the size of these groups (or "caches" as I prefer to call them) of squid is almost limitless! For maximum effeciancy in these groups the squid talk to each other and help each other out. The communication between each squid relies primarily on each squids role in the "cache" and can be anything from a "parent" or "child" squid to "siblings" (please note these relationships no not denote the lineage of family groups, but simply the authoritive role each squid plays). From what I have seen you could be quite close to one of these "caches" right now and not even be aware of it!

Kraken

[Ironsides]

I'm reminded of the old "tales" that seamen told when they came back from sea. Circa ~1400s, give or take a few centuries. There was a giant seamonst that looked a lot like a giant squid, except it had a beak below the eyes on the outside of it's head. Well, giant squid have a beak, it's just betweent he tentacles instead. Here's a picture of a Kraken. Look familiar?

An even bigger species than the Giant Squid...

[DesScorp]

...is the colossal squid, Mesonychoteuthis hamiltoni. Where giant squid are thought to get up to 60 ft long, no one knows just how large the CS can get. Remains of the two species have been compared, and the CS is bigger in just about everything, including the beak. They live only in Antarctic waters (that we know), and the remains of one washed up in the Ross Sea in 2003.

Ummm, no, not EVERY time...

[DesScorp]

...according to this:

In 1965, a Soviet whaler watched a battle between a squid and a 40 ton sperm whale. In this case neither were victorious. The strangled whale was found floating in the sea with the squid's tentacles wrapped around the whale's throat. The squid's severed head was found in the whale's stomach.

Re:Skip a beat, eh?

[Neo-Rio-101]

Although it looks like it on the outside, Japan is not open about sex at all. Otherwise all my Japanese colleagues would be having orgies every second week - but none of them can even get a date. In fact, it's not very open socially much at all. Non-comformity is flattened by society as it ignores anyone loud who dares stick out. Anyone trying to get attention is viewed as an attention whore and is summarily ignored. Anyone who truly NEEDS attention is ignored as well - which is the sad part.

IMHO the whole sex perversion thing is basically due to hordes of men not being able to get laid. Pure and simple. That frustration has got to come out somewhere. The reason they can't get laid is that most of the men are unromantic, selfish, uncaring, and have no respect for women basically. The only reason why foreigners get laid is because they are the exact opposite of Japanese men, and have blonde hair.

The whole octopus thing extends farther back than mere penis censoring. I have seen old Japanese art depicting Japanese women being mauled by octopus. Why octopus, you may ask? I don't know, but since the Japanese eat so much of it I figure "you are what you eat".

Re:WOW.

Sperm whales can't get enough of them, apparently. I once saw some utterly incredible TV footage where they'd stuck a camera to the back of a sperm whale in the hope of seeing a giant squid when it went hunting. The camera was designed to pop off once it reached a certain depth so that they could recover it. They didn't find any squid, but the whale behaviour was amazing. There was a whale on either side of the one carrying the camera as they went diving down, and all the way they were chattering away to each other. At one point, they stopped (the depth was displayed in the corner of the screen), had a bit of a discussion, then the whale on the right swam right up to the camera and the screen was filled with whale eye. A few seconds of staring later, they had another chat among themselves and carried on. It seemed pretty obvious to me that the camera-carrier had said "hey, there's something stuck to my back, would you check it out?" and the other whale had a look, said words to the effect of "move on, nothing to see here" and off they went...
