The thing about octopus is they have a copper/iodine blood system that allows them to change colors instantly. The common octopus that Shari posted is brown in color, that is when it is under no threat...Pictured here is a Caribbean Reef octopus that is in it's happy, just cruisin', not threatened mode....When frightened, they turn solid white, when mad, reddish brown, etc...they change color so fast it's amazing....No, it's not the mirrors!! LOL..
