Jinsi ya kumtambua

The body looks rough because the scales have raised keels, most noticeable on the rows along the sides.1
The head is blunt, which is one reason for its scientific name.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its bites are similar to rattlesnake bites in the United States. Local effects can be severe, with pain, massive swelling, blistering and necrosis (death of tissue), which may need surgery to relieve pressure (fasciotomies) and in some cases amputation. Whole-body effects are rare, including bleeding problems, kidney failure and nerve damage (neurotoxicity). Only the venom of young snakes (neonates) contains crotoxin, a toxin that causes nerve symptoms.1

Akiuma

Mweke mtu bila kutikisika na mtulivu, weka kiungo kilichoumwa usawa wa moyo, ondoa pete na vitu vinavyobana, na umpeleke hospitali haraka.

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
