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

Ekhaya

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

Ubude

Esona santya siphezulu

malunga ne-25 km/h (16 mph)

Ukuqubha, uqikelelo nje

Sitya ntoni?

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

Amandla etyhefu yokuluma nokuhlaba

Ukuluma

Ityhefu iphuma ngamazinyo aso etyhefu okanye ngamazinyo aso xa siluma.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Senza ntoni xa soyika?

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

Ukuba siyaluma

Ukubopha ngoxinzelelo nokunqanda ukushukuma (pressure immobilisation): songa ibhandeji eqinileyo enwebekayo phezu kwendawo elunyiweyo uze unyuke ngelungu lonke, uliqinise ngesiplinti, kwaye ugcine umntu engashukumi kwaphela de kufike uncedo.
Ingwane enamakhonkco aluhlaza okwesibhakabhaka okanye inkumba ye-cone inokwenza umntu ayeke ukuphefumla esaphaphile: biza uncedo kwaye ulungele ukumphefumlela (rescue breaths) de i-ambulensi ithathe izintambo.
