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.
A blue ringed octopus is only 12 cm long from the top of its body to the bottom of its tentacles.
About 5 inches
about maybe a pound
26 grams
5 to 10 cm
The blue ring octopus eats crabs, invertebrates and wounded fish.
One of the predators of the blue ringed octopus is the moray eel.
