According to the article the females don't fare any better either.
I didn't know this about octopi, what's the point, evolutionarily, to self destruct after reproducing?

what's the point, evolutionarily, to self destruct after reproducing?
There is no point, evolution is about successful reproduction and everything else is just random chance.
If a evolutionary tweak happens that gives your off spring better chances, but your arms fall off after sex then it'll probably perpetuate.
-
Maybe them dying is the bonus, eliminating the old blood.
-
Essentially their entire mating cycle is what causes this. They've got a gland behind the eye that puts them into mating mode and once it starts it never turns off until they overdose on sex hormone.
Most cephalopods are voracious hunters that eat and eat to grow big and then once mating mode switches on they just focus on mating, which results in a shit ton of babies. Every step of that cycle has an extremely high mortality rate resulting in strong selection pressures for the best of every phase. When they do something, they go big.
-
There's a specific life history strategy called semelparity, which is what you're describing (breeding once then dying). To my understanding, this is incentivized if the chances of getting a second attempt to breed are too low, and so it becomes more evolutionarily advantageous to simply go all out on the first attempt
-
Semelparity: “Fuck it, I’m gonna nut to death”
-
A bit similar process in sea-dwelling salmons: migrating from salt water into fresh water (quite a big metabolic challenge in itself), traveling up rapids to suitable spawning places (often a long and arduous journey)... after they've accomplished that, their chances of returning alive are quite low. So they mostly die. But their close relatives, river-dwelling trouts spawn many times in life, because their migration isn't as costly.
I would suspect that something in how octopuses reproduce has an element of "return being costly" - it could be a metabolic return to the feeding and growing state instead of a physical return.
-
That makes sense, if there is an organism that is a very good predator, and the chances to breed a second time are too low, then if the organism doesn't die it will be consuming the resources of those who can breed. Natural selection must prioritize having descendents over long living, because not having descendents is extinction.
-
To prevent decrepit politicians who already had their chance from usurping the resources of the next generation and pulling up the ladder behind them?
You know... Octopus politicians
-
Not everything in evolution ends up having a point. So long as a problem does not impact the propagation of children it can end up moving forward to the next generation.
I would guess that if there is an Evolutionary reason, it's probably that octopi with this drive reproduced More than octopi that didn't.
-
They reproduce so much because they forget they had already done it and believe they need to do it or else
-
-
Evolution doesn't care what happens to you after reproduction because you've already passed on your genes at that point
-
Take that point and explain humans living to about 100 after breeding from 20 to 40, and kids taking ~15 years to become good enough
Human tribes doing well is good for making children successful, old women have much better skills in finding whatever plant matter they're gathering, old men are better at tracking and stalking prey. The old people teach the young.
We evolved towards longer lifespans because groups that live longer survive and continue better

-
whatever works...
-
I read that it's so the parents don't compete for resources with their young, helping to support the young's survival
-
Fair, another possibility, thanks for the answer
-
-
Reproduction is the goal. It could be as simple as giving the young a chance to out compete their r****ded parents for limited food.

This is how biologists interpreted ghosting
-
This happened to me. No joke. I lost half a standard deviation from my iq for each child i had. #dunceLife
-
Are you sure it's not because of chronic exhaustion for several months in a row instead of the sex?
-
I can keep it up for a good while, but several months is excessive.

He never said the kids were his...

The literal version of "man has enough blood to operate his brain or his penis, but not both at once."
-
Same tbh
-
yep. now i’m a dad!

Good. They deserve it. Octopuses are dicks. They keep demanding you to call "octopi." Sure. When you start calling me and my homies squidi, I'll start calling you guys octopi.
But no, they can't see past their octopus privilege. As if having two fewer arms made them superior.
-
Octopi is the oldest plural form of octopus, coming from the belief that Latin origins should have Latin endings. However, octopus is not a simple Latin word, but a Latinized form of the Greek word októpus. Consequently, its “correct” plural form would logically be octopodes.
Nowadays "octopodes" and octopuses" are both acceptable, the latter being more regularly used.
"Squid" on the other hand isn't Latin or Greek, of unknowns origin, probably from a sailor's variant of "squirt"; late 15c., squirten, squyrten "to spit water from the mouth" (intransitive), a word of uncertain origin, perhaps via Middle Dutch or Middle Low German, probably ultimately imitative.

Post nut catastrophe :/
