Bay of Bengal blue-ringed octopus
The Bay of Bengal blue-ringed octopus is a small sea creature that hides in rock crevices and coral reefs. It is one of the most venomous marine animals in the world, even though it is only about the size of a hand. Its blue rings are a warning to keep away.1

Poder del verí
El verí surt pels ullals o les dents quan mossega.
Què fa el seu verí?
Its venom contains tetrodotoxin, a neurotoxin (a poison that attacks the nerves). It causes paralysis of the muscles and can stop breathing within minutes. Victims stay fully aware but cannot move, and the venom can also cause nausea, heart failure and blindness.1
Com de perillós és per a les persones?
Perill per a les persones: Molt perillósPot matar una persona que no rep tractament.The octopus carries enough venom to kill more than 20 adult humans within minutes. Its bites are tiny and often painless, so victims may not realise they have been bitten until breathing problems and paralysis begin. Estimates of recorded human deaths range from seven to 16, and most scholars agree at least 11 have occurred. Children are the most at risk because of their small body size.1
Què fa quan té por?
It first tries to flee. If the threat continues, it takes a defensive stance and flashes its blue rings, and if cornered and touched it may bite.1
Si mossega
- First aid is pressure on the wound, followed by artificial respiration as soon as paralysis stops the victim breathing. Respiratory support should continue until medical help arrives. In hospital, the patient is put on a ventilator until the toxin leaves the body, and those who survive the first 24 hours usually recover completely.1
- Immobilització amb pressió: embolica amb una bena elàstica ferma la mossegada i després tota l'extremitat, posa-hi una fèrula i mantén la persona completament quieta fins que arribi l'ajuda.
- Un pop d'anells blaus o un cargol con poden aturar la respiració d'una persona mentre encara està desperta: demana ajuda i prepara't per fer respiracions de rescat fins que l'ambulància se'n faci càrrec.

Estigues segur
- No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
- Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
- Si te'n mossega un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.
No va a per tu. Fa servir el verí per caçar o per defensar-se, i prefereix mil vegades amagar-se. Més sobre com estar segur

Dades
The blue-ringed octopus was the first animal reported to use tetrodotoxin as a venom. The same toxin is also found in pufferfish, rough-skinned newts and some poison dart frogs.1
The mother may inject the toxin into her eggs, which may then make their own venom before hatching.1
The octopus produces its venom using bacteria living inside its posterior salivary gland.1
Its blue rings flash in less than a third of a second, using muscles under nerve control. This is a warning display.1
The octopus's own body is resistant to its tetrodotoxin, so the venom does not harm it.1
In the 1983 James Bond film Octopussy, the blue-ringed octopus is the symbol of a secret order of female bandits and smugglers.1
Desmuntamites
Mite: Because it is small and relatively docile, the blue-ringed octopus is harmless.
Veritat: It is small and usually calm, but it is very dangerous if it is provoked or handled. Its venom can kill a healthy adult within minutes if not treated.1
