In a fascinating glimpse into octopus behavior, researchers have documented female gloomy octopuses (Octopus tetricus) engaging in what appears to be deliberate projectile throwing — targeting other octopuses with shells, silt, and algae propelled by jets of water from their siphons. A peer-reviewed 2022 study in PLOS ONE analyzed around 21 hours of underwater footage from Jervis Bay, Australia (2015–2016), revealing dozens of these “throws,” especially during social encounters such as fights, a

The underwater octopus settlement known as “Octlantis” is indeed real — a remarkable discovery made near Jervis Bay, off the coast of New South Wales, Australia. First documented in 2017 by a research team led by Professor David Scheel of Alaska Pacific University, along with collaborators from Macquarie University and the University of Illinois, the site revealed surprising social behavior among gloomy octopuses (Octopus tetricus). At Octlantis, scientists observed octopuses living in close pro
