Kuogelea, makadirio

Hula nini?

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

Jinsi ya kumtambua

When calm, its colour is a drab, mucus-like colour.1
When threatened or aggravated, about 60 rings suddenly appear and flash blue-green.1
As an adult, it is up to 20 cm long, from the top of the mantle to the tip of the arms.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hatari kwa watu: AnauaMmoja wa wanyama hatari zaidi duniani.

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

Hufanya nini akiogopa?

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

Akiuma

Get immediate medical attention, because a bite is often fatal without it. No antivenom exists.1
Kubana na kutotikisa: funga bandeji nyororo kwa nguvu juu ya jeraha kisha mguu au mkono mzima, weka banzi, na umweke mtu bila kutikisika kabisa hadi msaada ufike.
Pweza mwenye pete za bluu au konokono koni anaweza kusimamisha pumzi ya mtu akiwa bado ana fahamu: omba msaada na uwe tayari kumpa pumzi ya uokoaji hadi gari la wagonjwa lifike.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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

Kuvunja dhana potofu

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

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