Irya iki?

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

Ibintu by'ukuri

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

Usenya ibinyoma

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

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