You wouldn't think that the so-called gloomy octopus would be the stand-out socializer in its genus. Octopuses are notoriously bad at getting along with each other, and in almost all cases seem to live out their lives in isolation. They might fight for resources, and males are driven to risk a female's wrath in order to briefly mate. But other than that, they pretty much fly solo. Even devoted octo-moms, who basically spend their whole adult lives brooding their eggs, wander off to wither away and die instead of interacting with their hatchlings. As far as we know, anyway. These creatures are difficult to study, so scientists are only just starting to uncover their secrets.
