The greater blue-ringed octopus is a small sea creature that lives in the warm shallow waters of the Indo-West Pacific, including around Australia. It is one of the most venomous marine animals in the world, so knowing what it looks like matters.1

It lives in shallow water over mixed seabeds such as rubble, reefs and sand. It hides in a burrow and comes out only to find food or a mate. The entrance to its burrow is littered with leftover crab and shell remains, which makes it easy to spot.1

It eats small crabs, shrimp and molluscs, and sometimes small injured fish. It pounces on prey, seizes it with its arms and pulls it to its beak, which pierces the shell or exoskeleton and releases venom.1

Ubuthi baso benzani?

Its venom contains tetrodotoxin (TTX), a powerful neurotoxin, which is a poison that attacks the nerves. It paralyses the muscles needed for movement, and in people it can lead to death through respiratory paralysis, which means the breathing muscles stop working. Symptoms include tingling and numbness of the face and lips, sweating, severe headaches, dizziness, speech problems, weakness and vomiting. Symptoms can appear between 15 minutes and four hours after a bite, and the victim stays conscious throughout.1

The bite is capable of being fatal to humans. The bite is painless, so a person may not notice it. Children are more sensitive to the toxin. Death can occur between 20 minutes and 24 hours after symptoms begin.1

Senzani uma sesabile?

It flashes its blue rings as a warning to predators, and it uses its venom to defend itself.1

Uma siluma

Ukubopha ngokucindezela nokuvimba ukunyakaza (pressure immobilisation): bopha ibhandeshi elinwebekayo eliqinile phezu kwenxeba bese ukhuphuka nesitho sonke, usiqinise nge-splint, futhi ugcine umuntu engashukumi nhlobo kuze kufike usizo.
Ingwane enezindandatho eziluhlaza okwesibhakabhaka noma umnenke we-cone ungamenza umuntu ayeke ukuphefumula esaphapheme: biza usizo futhi ulungele ukumphefumulela (rescue breaths) kuze kufike i-ambulensi ithathe izintambo.

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.
