Dangers: The Blue Ringed Octopus packs a small bite that is often painless some not even realising they have been bitten till intoxicating signs begin to show. a small golf ball sized blue ringed octopuses bite contains enough venom to kill 22-26 adult peoples in minutes. the venom can cause respiratory arrest, nausea, heart failure, blindness, and even total paralysis.
Treatment: there is not yet an anti-venom however if you are with a friend they must get you to safety and prepare for mouth to mouth first aid. it is known that if you survive 24 hours after being bitten you will make a full recovery this is why it is rated one of the top dangers of the ocean.

This diagram shows the anatomy of the Greater Blue Ringed octopus. it shows that the brain takes up most of the octopuses head suggesting it is a more advanced and smarter animal of the ocean.
"Only three known deaths have been registered, but the danger is so present in Australia that many beaches have signs warning against the presence of Blue-Ringed Octopuses." quotes 'FightNetwork' which can be inferred that the danger of the blue ringed octopus is not too great however it is still a good idea to stay well away from one if you see it.
Encounters: only three people that are known have died from blue ringed octopuses however the danger is so great in Australia that sign's have been put up at beaches where Blue Ringed Octopuses are known to bread/ live.
This diagram shows the breeding grounds and areas of significant population for the Blue Ringed Octopus. The diagram shows that the Blue Ringed Octopuses breeding grounds are mainly down the bottom of Australia suggesting that the Blue Ringed Octopus likes colder areas. They are found in the Indu Australian Region however the Blue Ringed Octopus can be found much further up from between Japan to Australia.
Prevention of danger: stay at least 1 meter away from the blue ringed octopus at all times as the blue ringed octopus has a very short temper. make sure you are always wearing a full body wetsuit when entering their habitat and do not take anything from their reef.
"Don’t touch, poke, play with or stand on any blobby animals near or on beach in Australia. Whether they are Jellyfish or Blue Rings they won’t do you any good!" states the BugBog organisation (2016). This is because if you are to "touch, poke or play" with this creature it could become aggressive and do some harm to you.
The graph above shows the population movement for the Blue Ringed Octopus. it can be seen that the numbers started from 20300 and have been reduced by 6000 this suggests that Blue Ringed Octopuses are either being hunted or their home is being destroyed.
