Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its saliva contains a neurotoxic venom, which attacks the nerves. It delivers this venom at the base of the skull of its prey, and the venom paralyses prey even when the prey is larger than the shrew. Tests on field voles showed the venom is lethal at a minimum dose of 15 mg per kg of body weight.1

Ana hatari gani kwa watu?

Hatari kwa watu: HafifuKama kudungwa na nyuki au chini ya hapo. Kimsingi hana madhara kwa watu.

Hantaviruses have been detected in shrews in Hungary and Poland, which raises public health concerns, although how the virus spreads is largely unknown.1

Hufanya nini akiogopa?

Its venom is thought to immobilise organisms that may threaten it.1

Akiuma

Osha jeraha vizuri na utafute msaada wa kitabibu.

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

It is one of the few venomous mammals. Its venom comes from glands at the base of its lower front teeth, and grooves along the teeth channel the venom into the bite.1

Its teeth are tipped with red because of deposits of iron, which harden the enamel of the tips.1

It can dive up to two metres underwater and stay under for about twenty seconds before it must surface to breathe.1

Its short fur holds air, so its skin stays dry while it swims.1

It has a home range of about 500 square metres, but when foraging on land it can travel up to 3 km.1
