In a study , for example, a 4-year-old boy survived a blue-ringed octopus bite. He received intubation and oxygen from a ventilator within 30 minutes of being bitten.
The paralysis from the venom began to wear off after 15 hours, and doctors removed the ventilator after 17 hours. The study reported that the child had no long-term complications from the bite.

Aaron couldn't move or talk, not even to comfort his distressed children, and just had to focus on surviving. He ended up in hospital for the rest of the day and it took the best part of a week for him to fully recover from the bite.
It's pretty weird. Mr Hodgson copped what turned out to be a mild dose of blue-ringed octopus venom, which contains a highly dangerous chemical called tetrodotoxin that paralyses muscles. Like other octopuses, blue-ringed octopuses have a beak, and their venom is secreted from its salivary glands.
In the worst case, a dose of the venom can shut down muscles such as those that keep you breathing and cause death within 30 minutes. There is currently no antivenom. Those bitten need urgent medical help and may need artificial respiration until the effects of the venom subside.
But the good news is that only a couple of people are bitten each year in Australia, and only a handful of deaths due to blue-ringed octopuses have ever been documented worldwide. This is because the animals are very vulnerable to predators and hide during the day, tucking themselves behind rocks or, as Mr Hodgson discovered, among shells. They can also hide in discarded bottles and cans in the water, so be wary of collecting these. It's also a good idea to be careful when exploring rock pools and not disturb them too much.
Octopuses come out at night to hunt so if you're doing a bit of nocturnal swimming, keep an eye out then too. With a body just several centimetres wide, a blue-ringed octopus can look really cute, especially when they start showing off their stunning iridescent blue markings.
But beware: this is a sign they are feeling threatened and might inject you with venom, as Mr Hodgson learnt the hard way. Like all octopuses, the blue-ringed octopus has eight arms equipped with suckers.
These help it to catch prey. The bright blue rings warn other animals that the octopus is deadly. They appear only when the octopus feels threatened.
