What's in the space between the brain and the skin? Is it just transparent fluid - csf? The space between the eyes seems to have something else going on, as in less transparent.

The space between the eyes is the brain.

Although brain is a fluid concept in these creatures, pressure right there will instantly kill the octopus, not because it is another organ but because it is the control center.

The article says the reddish mass(es) is the distributed brain, but was referring to the separate white band between the eyes.

Interesting point about pressure.
