Octopi Time!

 I remain, as always, fascinated by octopi. Listen to this:

So there is a lot going on in the arms, but the connections between arms and brain are apparently restricted to a narrow channel. ...
If you were an octopus, distinctions [in moving your limbs] would be blurred. Your arms would move in a way that is a mix of the centrally and peripherally controlled. To some extent you would guide them, and to some extent you would just watch them go.

Which explains the absolutely eerie way in which they move combined with the intelligence in their eyes. Well, that and the lack of bones.
