I could be wrong about that. I learned this in a microbiology course 10 years ago. So the focus was on the bacteria and the quorum sensing rather than the ecology of the octopus.

Here's the wiki on the octopus species though. https://en.wikipedia.org/wiki/Euprymna_scolopes

I see. This is a sepiolidae. In a different superorder than octopuses then. Neither a squid nor a octopus; a close relative to cuttlefishes.
