Hi! I do not promote this at ALL but I know it’s a practice done in Japan... so my Friday evening thought is why, when octopus arms are cut off (for food in Japan or eaten by another creature underwater), do octopus arms not bleed... I would love to know. I have been studying octopuses for a year now and actually this never occurred to me... but ZERO blood. Very strange. Let me know any thoughts!!

Funny, I just saw a reference today somewhere about an octopus' blood being blue....
I think the fact that its blood is rarely seen may be attributable to the relatively low % it makes up of its mass, but I am not sure on that. Here's a prior discussion on the topic!

A Bleedin' Octopus!
My apologies, folks from UK and Australia -- I don't mean it that way. In videos that I've seen, octopus blood is rarely visible, and when it is it's not guaranteed to be distinct from an inking response to fear/injury. Even in videos showing cutting of live animals (ugh!), I understand that...
