Sidlani?

It eats mostly lobsters, crabs, shrimp and shellfish, including bivalve molluscs, and sometimes small fish. It pins down prey and injects venom through its beak, which paralyses the prey. It can also release venom as a mist into areas where prey gathers, so that prey swim into it and become paralysed.1

Amandla obuthi

Ukuluma

Ubuthi buphuma ngamazinyo aso obuthi noma ngamazinyo uma siluma.

Ubuthi baso benzani?

Its venom contains maculotoxin, a deadly neurotoxin (a poison that attacks the nerves), and tetrodotoxin (TTX), also a neurotoxin. Without immediate medical attention, a bite is often fatal to humans.1

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KuyabulalaEsinye sezilwane eziyingozi kakhulu emhlabeni.

The octopus is normally docile, but its venom can kill a human. A bite is often fatal without immediate medical attention. No cases of unprovoked aggression towards humans are known.1

Senzani uma sesabile?

When threatened, its drab colouring gives way to flashing blue-green rings.1

Uma siluma

Get immediate medical attention, because a bite is often fatal without it. No antivenom exists.1
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.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

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.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

Females only reproduce once in their lifetime. After the eggs hatch, the mother dies shortly afterwards, as she does not eat while guarding them.1

Young blue-ringed octopuses have no planktonic stage. They begin hunting at around one month old.1

The average lifespan is around seven months. The octopus reaches sexual maturity at about four months old.1

Females are choosy about mates. They are more willing to mate with larger males, and larger males try to mate more often than smaller ones.1

Inganekwane: Popular culture portrays the southern blue-ringed octopus as a sea devil that lies in wait to attack humans.

Iqiniso: Its venom is mainly used for hunting or defence. There are no reported cases of unprovoked aggression towards humans.1
