Octopi do something similar but at least they meet up, the dude will just hand her his dick tentacle for later. Octopi being octopi I would assume it grows back.

Most cephalopods die after mating. Their sex hormones make them go crazy and they stop looking for food except to eat themselves occasionally. Once the sex hormone glad starts pumping them out, it doesn’t stop until they die a horrible death. Live fast and die young.

I was very excited about humanity killing itself off and letting the superior line of sapience take over until I learned this fact. It’s going to be a bit before the octopi are ready to create a civilization.

They don’t do any parenting, either. Nor do siblings ever team up. Baby octopus just has to take care of itself, alone.

It’s weird, they’re so intelligent, but don’t teach anything to the next generation.

Arguably the biggest reason they don’t develop civilizations; you have to be able to pass learned knowledge on down generations.

Sooner or later some octopus will survive beyond reproduction and then we can welcome our new mollusc overlords
