Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

This snake has enlarged rear teeth that are not grooved, and they are linked to a gland that produces oral secretions with proteolytic activity, meaning they break down proteins. In the few serious cases, symptoms included severe swelling, bruising, numbness, itching and dizziness. Most bites cause only mild pain and minor swelling.1

Ana hatari gani kwa watu?

Many bites have been recorded, but only four cases of significant reaction in humans are reported for this species. It is considered mildly venomous.1

Hufanya nini akiogopa?

When threatened, it flattens its neck like a cobra, and can flatten lower parts of its body too, to look larger and more intimidating.1

Akiuma

Osha jeraha, mweke mtu mtulivu na utafute msaada wa kitabibu. Baadhi ya spishi (kama boomslang) zinaweza kuua saa kadhaa baadaye.

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

Captive-bred individuals can become quite tame and trusting, and many show a high level of intelligence.1

Temperaments vary a lot: some individuals are docile, while others are defensive or even aggressive.1

Males are much smaller than females, a difference called sexual dimorphism.1

It is mainly active during the day, which gives it good daytime vision thanks to its large eyes.1

Kuvunja dhana potofu

Dhana potofu: It is a true cobra.

Ukweli: It is not a true cobra. It hoods in a similar way, but stays horizontal instead of rearing up.1
