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

Leef in

Tropical and subtropical Indo-West Pacific, from Sri Lanka to the Philippines, and from Australia to Papua New Guinea, the Solomon Islands and Vanuatu1

Indiese Oseaan, Stille Oseaan, Koraalsee, Filippynse See, Timorsee & Arafurasee

Tuis

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

Lengte

Topspoed

Wat eet dit?

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

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: DodelikEen van die gevaarlikste diere in die wêreld.

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

Wat doen dit as dit bang is?

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

As dit byt

Drukimmobilisasie: draai 'n stewige elastiese verband oor die byt en dan op oor die hele arm of been, spalk dit en hou die persoon heeltemal stil totdat hulp opdaag.
'n Blouring-seekat of keëlslak kan 'n mens se asemhaling laat stop terwyl hy nog wakker is: roep hulp en wees gereed om asemhaling (mond-tot-mond) te gee totdat die ambulans oorneem.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly
