How I got here
- Started with
- Do octopus arms have brains?
- Ended at
- “are cuttlefish colorblind”
The Trail
- “do octopus arms have their own brains” (google.com)
- Octopus (en.wikipedia.org)
- Cephalopod intelligence (en.wikipedia.org)
roughly two thirds of the neurons are in the arms, not the head
- Chromatophore (en.wikipedia.org)
- Cuttlefish (en.wikipedia.org)
- “are cuttlefish colorblind” (google.com)
What I came away with
About two-thirds of an octopus's neurons are in its arms, which can taste, touch, and make some decisions locally. And somehow cephalopods camouflage near-perfectly while (probably) being colorblind, which nobody has fully explained.
