| I have this headcanon that an ancient ape civilization was at war with cephalopods and they created a weapon of mass destruction that artificially gimped octopus lifespans :'( |

| There is only one species of octopus that lives socially (LPSO are rare and incredibly intelligent but their lifespans are like 3 years) Maybe your headcannon should be that apes did a "tower of babel" type thing to make all the octopus individualistic and unable to organize into a civilization |

| ▲ | culi 42 minutes ago | parent [-] | | Well the LPSO is the only consistently social octopus. "Octopus city" was actually 2 cities (the second one being discovered in 2016) and they were groups of about 15 gloomy octopuses. There are a couple of other examples of octopus sociality but on a species-wide level only the LPSO can be comfortably described as social Almost all octopuses are cannibalistic but Abdopus have also been found living close to and tolerating each other |

| mutations that occur after reproduction are never weeded out since the genes are passed on already, so natural selection on its own can result in this, just like cancer or lower safeguards against cancer such as short telomeres in humans |
