Octopuses, once thought to be loners who lived and hunted with little interaction from others of their kind, are actually quite social.
Scientists have discovered a village of sorts used by more than 50 octopuses on the sea floor about 17 metres deep in Jervis Bay south of Sydney.
The site is a flat area formed around an unidentified, partially buried artifact which provides places to hide, or dens, for octopuses.
