...and smothered in soy sauce, will continue to move about. This is pretty bizarre. Not sure I'd be able to eat it.

Think it's just a matter of nerves. Most things will still jerk about a bit after you kill them.

Creepy, gross, and kind of horrifying.

It is. The salt in the soy sauce triggers it.

Regardless, that still makes me feel incredibly bad. I couldn't even watch the entire 42 second video, I felt so bad for the poor thing.

I'd have guessed that a squid with its head cut off was a pile of loose tentacles.

I'm far from an expert (clearly) but I don't think the biological system of a squid is advanced enough for it to really suffer in that sort of situation.

Well, considering that I've done a "live" baby octopus sushi shot, this is something that I'd eat. After you eat balut, you can pretty much eat anything.

Be that as it may, it's difficult to divorce that from seeing it in what I would assume would be the throws of agony.

Serious questions: So, if it's "just the nervous system reacting," what does that mean exactly? How do you know that it doesn't feel pain? Simply because it has no brain to tell it's body that it hurts?

I never did well in biology, so I've always been a little hazy on that sort of thing.

I don't really know. It's something I learned in the course of hunting rather than school.

If you detach the head from the body then I reckon it's assured that the thing is dead. I don't figure it feeling much pain after that, despite its movement.

I just don't know enough about biology to know what makes you feel pain.

Pretty much. The salt provides the ion to create the electrical charge to fire the nerve synapse that's no longer being created by the agonized brain.

What I wonder is, if the squid was only unconscious but alive (of course it would still have to have it's head on) and you poured soy sauce on, would it act similarly?

I imagine it would. It's probably an autonomous instinct to try to get away from something.

(I think I used autonomous correctly.)

I've seen balut. It made me feel ill. There were feathers in it!

Here's what lolwiki has to say on the issue:

wikipedia wrote:
An octopus has a highly complex nervous system, only part of which is localized in its brain. Two-thirds of an octopus's neurons are found in the nerve cords of its arms, which have limited functional autonomy. Octopus arms show a variety of complex reflex actions that persist even when they have no input from the brain.[9] Unlike vertebrates, the complex motor skills of octopuses are not organized in their brain using an internal somatotopic map of its body, as is the motor system in vertebrates[10] Some octopuses, such as the mimic octopus, will move their arms in ways that emulate the shape and movements of other sea creatures.

The neurological autonomy of the arms means that the octopus has great difficulty learning about the detailed effects of its motions. The brain may issue a high-level command to the arms, but the nerve cords in the arms execute the details. There is no neurological path for the brain to receive feedback about just how its command was executed by the arms; the only way it knows just what motions were made is by observing the arms visually.[13]


Kind of interesting. Seems like the arms behave semi-autonomously. Unfortunately I couldn't find out anything about how that affects its pain reception.

Au contraire, I find your sexual habits with Puerto Rican youth boy bands to be equally, if not more creepy.

Pain is a signal interpreted by the brain. No brain, no pain.

But the bulky nervous structure in cephalopod arms is what is responsible for this complex movement. There are many organism that substitute dense nerve structures for what we would call a brain. I don't specifically know what aspects of information are handled by the arms, but it's not as simple as "no brain, no pain."

It's essentially galvanization, which I imagine most people are familiar with. There was that fella named Galvani who used to electrocute dead frogs to make them twitch a couple of centuries ago. Naturally that kind of black magic caused quite a buzz back then.

Even insects are capable of feeling pain despite lacking a complex nervous system, but pain is not the same thing as suffering. Pain is just a sensory experience, like sight, temperature, hearing, etc.. Certain squid consist of some of the most intelligent species in the animal kingdom, which is probably new to no one.

That said, I sort of doubt that any animals are capable of suffering the way it is conceived of by humans. There's seemingly an exceptional amount of intelligence and working memory required to attain sentience, which is critical to the development of identity. Essentially, imagine if you were in crippling pain, but slept right through it. Or liken it to the experiences where you felt immense pain as an infant (which you surely don't recall at all).

To suffer, something must be able to recognize that it has an identity, that said identity is in peril, and it must be able to emote that realization. Couple that with even the fact that even the brightest animals would be considered profoundly retarded by human standards, and I wouldn't worry myself with their feelings. Those are my conclusions, at least.

Aren't you a pediatrician, or something? You probably stab little kids every day, right? Smiley: tongue

Smiley: dubious

I think you're taking a ton of liberties with that conjecture.

Well feel free to publicize what you differ with, but it's less taking liberty and more a habitual history of being informed. It's always possible that my information is a miss, though.
