Here's the never-before-seen 'octopus city' scientists recently discovered

A group of scientists discovered an underwater "octopus city" off the coast of Australia in Jervis Bay, and they've named it "Octlantis."

This discovery of octopuses interacting in a high-density den challenges scientists' previously held belief that octopuses are solitary and antisocial creatures.
