edit: to clarify, they're MAGNIFICENT creatures, and are a testament to the unfeeling unemotional beauty of actual Evolution - it has no plan. It is random. It only works because of odds. That some traits get selected for more frequently ON AVERAGE.
Sometimes that can lead to some interesting places...octopus, platypus, narwals. Hell, most animals are RIDICULOUS when you get down close.
But this curse of the octopus's intelligence being severely artificially limited so they can't progress and evolve.
Maybe the meaning of life is for us to use our technology and medicine to help the Octopuses live long and fulfilling lives and put them on a path to continuing evolution and together the human and octopuses species are meant to conquer the galaxy.
Alas, in this dimension, we fucked up and destroyed their habitat instead.
Asking for friend.

As a reproductive strategy for an (arguably) intelligent animal ... this makes me feel sad. However there's plenty of octopuses around so in evolutionary terms it's a strategy that works.
As for the males - and this is the point at which my anthropomorphic 'yuk' reflex goes into overdrive - they die soon after their first successful sexual encounter. Males store sperm in one of their arms. For some species, 'sex' involves detaching that arm and giving it to the female to keep for later use. Then they wander off and die. Possibly from disappointment.
