Octopuses  have generally been viewed as solitary creatures--and their color-changing abilities primarily as a means to hide from hungry predators. But, after binge watching more than 52 hours of octopus TV,researchers reporting in the Cell Press journal Current Biology on January 28 have found that octopuses actually do have a social life. And it's not without drama. "We found that octopuses are using body patterns and postures to signal to each other during disputes," says David Scheel of Alaska PacificUniversity. "The postures and patterns can be quite flashy, such asstanding very tall, raising the body mantle high above the eyes, and turningvery dark."

The octopuses in question belonged to a species known as Octopus tetricus living in the shallows of Jervis Bay, Australia. Scheel and his colleagues were tipped off that something interesting might be going on in that bay by a diver whoalerted an online community of people interested in cephalopods that he'd seen something interesting. The researchers followed up from there, ultimately witnessing 186 octopus interactions and more than 500 actions. In all that video, the octopuses spent more than 7 hours interacting.

Scheel along with colleagues at the University of Sydney noticed some intriguing patterns: when an octopus with a dark body color approached another dark octopus, the interaction was more likely to escalate to grappling. When a dark octopus approached a paler one, the pastier octopus more often retreated. When the opposite happened and a light octopus approached a darker one, the latter more often stood its ground.

"Dark color appears to be associated with aggression, while paler colors accompany retreat," Scheel says.
