I used to love eating octopus, but since I've learned so much about their intelligence, I have not been able to bring myself to do so, anymore. I have the luxury of choice. There are many, in this world, that do not.

Consider the intelligence of pigs as well. Even if cows, sheep, deer, rabbits, chickens, turkeys, et al. all sit below the "I don't want to eat you" cutoff point, pigs should probably be above it.

Not doing that is why future generations will loathe me and my generation.

The fish are able to gather food from the sand which the octopus moves. It happend to me too in the ocean where fish around my feet followed along the spots in the sand I touched. Therefore I was hunting together with fish!?

Yes, you just aren't as good at it as the octopus. Maybe if you practiced more?

Earlier quoted context omitted.

Typically octopuses produce offspring only near the end of their life, so eating them at any point is destructive for their reproduction and species health.

Eat them after they reproduced then, they only do that once in their life.

They typically die after reproducing. Mothers use their remaining energy to help their offspring survive, fathers sometimes do but not all - if you could somehow capture only post-mating male octopuses from species that don't sacrifice themselves for their offspring then sure, but that seems like an unrealistic expectation.

Incidentally, if, as per etymology, we consider the tentacles as feet, then the headline is wrong as the Octopodes are technically kicking the fishes.

Technically speaking, Octopuses don't have tentacles at all. Those are arms. The morphology of "Octopus" is actually a really great example case for demonstrating paraconsistent logic.

Hmm so the name must be corrected to be 8-armed in Greek. Oktobratso? Oktooplizo? Oktocheiro?

given how the octopus uses camoflauge, operating on their environment by using other fish as a distraction to their prey is logical. punching the still predator fish to keep them moving removes competition and keeps them moving as a part of the noise distraction.

longevity research for cephalopods seems like it could be really fruitful.

I’ve been able to give up eating cephalopods, but pigs are too delicious to give up.

Very cool! > “I think sociality, or at least attention to social information, is way more deep-rooted in the evolutionary tree than we might think,” Maybe, or maybe the neural power required to move all of those limbs is good enough at processing that they developed their own sophisticated behavior.

Well, given the overwhelming emerging evidence of social attention and behavior in plants, and given that it makes evolutionary sense that "social attention" would provide a fitness advantage in any environment where there are other actors,

the only reason to doubt it would be an assumption that "attention to social information" can only happen in creatures with an complex central nervous systems. Which requires rather constrained definitions of "attention", "social", and "information"

ok, there is another reason to doubt it. inertia. We've been taught/told that a complex CNS is what makes intelligence, and it is hard to get away from that idea.

It goes deeper than that! According to wikipedia, the tentacles, or appendages, are indeed called "arms", but they evolved from what in other molluscs is called a "foot"!

just because something is intelligent is no reason not to eat it imho

This is an honest question, I'm not making a joke. Why shouldn't we eat _you_ then?

while i do keep in shape and i'd certainly make for a juicy steak or filet, i doubt this culinary experience is worth ten years to life in prison.

I love imagining how the fish are almost an extension of the way the octopuses think. Octopuses seem to have quite a bit of independent cognition in each of their arms, which are wrangled by the central brain. Now they're wrangling independent fish brains instead of octopus arm brains. Incredible

You might enjoy 'Children of Ruin' by Adrian Tchaikovsky, which explores this idea in depth with a civilization of genetically modified, super-intelligent octopuses. (Though I'd start with the first book in the series, 'Children of Time')
