Would you count group hunting as “highly complex social behavior”? It’s not just a numbers thing, they communicate and coordinate with the group. https://www.npr.org/2024/09/23/nx-s1-5120912/octopuses-and-fish-hunt-enforce https://www.npr.org/2024/09/23/nx-s1-5120912/octopuses-and-f... Octopuses also build colonies, using coconut shells and other tools. https://www.newscientist.com/article/dn18281-octopuses-use-coconut-shells-as-portable-shelters/ https://www.newscientist.com/article/dn18281-octopuses-use-c... https://www.science.org/content/article/scientists-discover-underwater-city-full-gloomy-octopuses https://www.science.org/content/article/scientists-discover-... https://mashable.com/article/octopus-garden-colony-deep-sea-discovery https://mashable.com/article/octopus-garden-colony-deep-sea-... They can also solve human made puzzles. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0152048 https://journals.plos.org/plosone/article?id=10.1371/journal... As for knowledge transfer, we know that they can teach other how to perform certain tasks. But beyond that, there seems to be a lack of research. Do they have complex language and can they transfer abstract “ideas”? My guess would be yes, but they communicate through color changes in ways that we have a hard time understanding. It seems likely that birds and whales have complex language, but we haven’t cracked the code on that even though their communication is much more like ours. Hopefully we find out some day. https://www.scientificamerican.com/article/the-mind-of-an-octopus/ https://www.scientificamerican.com/article/the-mind-of-an-oc... https://www.forkingpaths.co/p/the-evolution-of-stupidity-and-octopus https://www.forkingpaths.co/p/the-evolution-of-stupidity-and...
