Related to the question: How could a climate-protection organization breed sapient, tool-developing cooperating Cephalopoda?
After breeding several lines of the Larger Pacific Striped Octopus (Wikipedia) for several decades in the secret research department of the Private Maritime Research Institute Aveiro, Portugal - which is connected to the Italian-German NGO "Salvare i Mari - Rettet die Meere!" and a couple of opaque companys financed by Structural and Research Funds (ERDF, ESF and ERC) of the European Union, donations and several economic activities - they succeded breeding two lines of highly cooperative, sapient octopuses which are learning from each other using a color/sign based language depicted on their skin and using/developing technology, advanced tools and even discussing development of underwater computers after getting information about human research regarding fluidics.
The scientists observed several big differences to human societies which made the communication pretty difficult as their perception of the world and of society differs quite alot from humans resulting in different directions their logical thinking leads them.
I would like to explore these effects and differences especially regarding their huge sexual dimorphism - females being bigger and having a much longer lifetime than males (which still die after mating, while the females live longer and mate several times).
What effects and differences would that have in the evolving octopus society?
Every thought on possible effects on any level of society is welcome. As the effects would certainly differ considering the time after setting free in the ocean it would be nice if you could specify some rough thoughts about the timeline this effect might occur.
