I have a question about octopus ink.
My personal experience has been wholly with large quantities of ink which cloud a tank instantly - it's thin and can't be removed by a panty hose net, but the skimmer does a good job clearing it up.
I once observed a a juvenile rubescens ink a small amount that could be removed by a net.
So is there a difference in the ink to produce these two effects, or this something the octopus controls? Is this due to age or the intent of the octopus in releasing the ink? Or does this vary with species?
