Sumu yake hufanya nini?
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

Hufanya nini akiogopa?
It flashes its blue rings as a warning to predators, and it uses its venom to defend itself.1
Akiuma
- 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
