In 2009, researchers found a site they dubbed Octopolis, where 16 octopuses lived in close proximity in dens off the coast of Australia. Researchers found octopuses at the site — the "gloomy" variety, Octopus tetricus — interacted in remarkable ways. "There's been this social dynamic happening at the site that you don't usually hear about when people are reporting octopus behaviour," he said. The researchers believe that one by one, the octopuses settled in the structure close to their food source, creating what some media called an octopus "city." Researchers have observed social behaviour from the octopuses at structures off the coast of Australia, something that comes as a surprise.
