Ekhaya

It lives in tidal rock pools and in crevasses and cracks in rocky reefs. It also lives close to seagrass beds. Like other blue-ringed octopuses, it lives in burrows.1

Sitya ntoni?

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 etyhefu yokuluma nokuhlaba

Ukuluma

Ityhefu iphuma ngamazinyo aso etyhefu okanye ngamazinyo aso xa siluma.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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?

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

Senza ntoni xa soyika?

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

Ukuba siyaluma

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

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba siyakuluma: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

kufanelekile ukwazi

Iinyaniso

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

Umqhekezi weentsomi

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

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