Members of the gloomy octopus species have created their own underwater settlement dubbed 'Octlantis'.
Situated in Jervis Bay on the coastline of eastern Australia, the remarkable Octopus 'city' consists of special dens constructed from sand and shells that can house up to 15 of the cephalopods.

The find is particularly unusual, not only due to the level of co-operation taking place but because the gloomy octopus was typically considered to be an isolated and solitary species.

To observe their behavior, an international team of researchers set up an underwater camera which recorded the animals meeting up, communicating and even chasing away rivals.

"These behaviors are the product of natural selection, and may be remarkably similar to vertebrate complex social behavior," said lead researcher David Scheel, from Alaska Pacific University.

"This suggests that when the right conditions occur, evolution may produce very similar outcomes in diverse groups of organisms."

It would be cool to see a gang of Octopi shaking 8 other tentacles at the same time. Like a big web of "hello"

Sounds to me like we're gonna be going to war with the Octarmy pretty soon. Kim Long Ams has his tentacle quietly hovering over the big red button, poised to send us back to to the cave.

Hadn't really thought about their social life. So, if you live alone in a house in a crowded neighborhood, you're not antisocial, you're just a wallflower.

Yes, or a shoal. A group of giant squid is called a school.
