What is the size of a blue ring octopus?

Answer 1

My brother caught one the size of a fist, but on this website: http://www.barrierreefaustralia.com/the-great-barrier-reef/blueringedoctopus.htm

it says "The blue-ringed octopus is the size of a Golf ball but its poison is powerful enough to kill an adult human in minutes"

Generally about the size of an average man's testicle. They are usually yellowish brown in colour and the blue rings flare up when they're disturbed or upset. They make quite a beautuful sight when this happens.
