I imagine the difference is that hermit crabs are exhibiting a rote, inborn behavior that is universal among the species. Cephalopods apparently figure this stuff out on the fly.
I don't know about rote or learned but they do figure it out on the fly and are willing to go with basically anything to protect their soft abdomen and keep it from drying out rapidly - including litter if it is their only option.

#63Octopi are interesting in that they evolved along their own path. The octopus eye has the wiring on the back, where it belongs, instead of on the front blocking some of the light, as most other animals with eyes do.

The location of the ‘wiring’ changes the type of information gleaned from the light field. There is no ‘wrong,’ rather, a variation in local optimization.

If you want an intelligent pet that will likely outlive you, get a parrot.
Actually, please don't. If you want a pet, adopt a dog or cat from the local shelter. At least they have been domesticated long enough that they are better off under human care. Don't keep an animal that had to be captured and removed from its natural habitat.

The prominence of the peak. Like how Denali is taller than the mountains around it, but Everest is still the tallest. We're quite close to dolphins and killer whales, so the essence of their intelligence is easier for us to understand, because they are more like us. Bees, termites, ants, etc. are really interesting because any individual is pretty stupid, but the entire swarm is complex and intelligent.
local maxima, in other words. Humans being the global maximum, on Earth at least.

#66> But Why? Arguably, there is no "why". You could say that they're an evolutionary dead end. But that's just speculation.
It also assumes free will in asking the quesiton.

#67How much of an impediment to technological progress would not have being able to tame fire have been? You probably don't need the warmth underwater, but cooking facilitates nutrient absorption ("exodigestion"?), wards off predators, post-sunset light, and (later) smithing, smelting, steam power etc.
A real world example of this is the isolated tribe of North Sentinel Island (who recently killed an American Christian missionary who smuggled himself there to prosyletize).
As best we can tell, they appear to not have learned to harnessing fire to this day.
EDIT: although the first anthropologist to contact the Sentinelese claims otherwise:

#68This is what a failed alien invasion / colonization attempt might look like. A succesful splashdown, reasonable adaptation to the local conditions — and a fatal flaw speeds up development enormously, bodies replicate and die long before their brains mature. The culture is lost, the invaders turned into animals doing primitive hunting.

I don't understand what the peak of intelligence means if that is termites, bees, humans? What about dolphins, dogs, not to mention chimpanzees, other great apes are likely smarter then them, but it will take some clever tests and clever categorization of intelligence to understand their sense.

Not sure why you got down voted. The ‘why’ does prejudice a creator :) It also assumes free will in asking the quesiton.
I was thinking generally about the fallacy of seeking intentionality in evolution. There is a point to analyzing what happened, of course. It's just that too much "why" is dangerous.
