But they
- Have extremely short lifespan so a limited capacity to learn (1-2 years)
- Don’t raise their offspring, in fact after mating/laying eggs they naturally die, so no knowledge sharing
- Are extremely solitary and don’t have social bonds or do anything socially, so little communication/passing of knowledge
I worked as an intern at a lab studying octopus vulgaris.
They are extremely sensitive to all sorts of things in the water. Keeping them well is very difficult. Although I would imagine if there are big but gradual changes in water environment, they would have a chance of adapting faster due to short life cycles and the fact that mating creates hundreds of thousands of eggs.
