Octopus Cities: What the Media Got Wrong

The "Octopus Cities" Misconception

• 🐙 The media has sensationalized discoveries in Jervis Bay, Australia, referring to octopus gathering sites as "cities" like Octopolis and Octlantis.
• 💡 While these sites are scientifically significant, they are not actual cities, and the term "city" is a gross mischaracterization.
• 📚 The exaggeration often stems from catchy headlines and a misunderstanding of scientific jargon like "ecological engineering."

What Scientists Actually Discovered

• 🔍 Researchers discovered two sites, Octopolis and Octlantis, where the gloomy octopus (Octopus tetricus) gathers.
• 🏠 Octopolis is centered around a human-made object, surrounded by collected scallop shells and debris used for dens.
• 🪨 Octlantis, found nearby, features gloomy octopuses building dens around patches of rock, also using debris like beer bottles and fishing lures.
• 🤝 These sites reveal that gloomy octopuses are more social than previously believed, engaging in behaviors like mating and territorial disputes.

Octopus Behavior and Sociality

• 🗣️ Octopuses have been observed "throwing" things, which is more accurately described as directed squirting, often as a territorial behavior.
• 🛠️ While not cooperative construction, individual octopuses do intentionally build and manage their own dens using collected materials.
• 🌊 Some octopuses use jets of water to clean their dens and may use inedible objects like sponges to create hatches.

The Reality vs. The Hype

• 📉 The main scientific takeaway is that these octopuses are not automatically solitary loners, but are socially adaptive and congregate when environments support it.
• 🏗️ There is no evidence of cooperative construction or a sustained sense of community, which are necessary for a true city.
• 🤔 Scientists are still researching the costs and benefits of solitary versus communal living for these octopuses, including aggressive behaviors and predator risks.
• 🌟 The discoveries at Octopolis and Octlantis are valuable for studying octopus behavior and filling gaps in our knowledge, with potential for more such sites to be found.
