Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

The venom is a complex mixture of proteins, including enzymes such as proteases and peptidases. It is hemotoxic, meaning it damages blood and destroys tissue. It also has neurotoxic properties, meaning it attacks the nerves.1

Ana hatari gani kwa watu?

The species has powerful venom and uses about 20 to 55% of its venom in one bite. It will defend itself if it is threatened or injured.1

Hufanya nini akiogopa?

It rapidly vibrates its tail to make a rasping rattle that warns intruders, and it will defend itself if threatened or injured.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

Ukweli

Females often gather in communal dens to give birth and care for their young. Some females even look after unrelated young while the mothers take a break.1

Newborn snakelets measure 22 to 28 cm and are venomous from the moment they are born.1

Prairie rattlesnakes prefer a straight migration path, even in areas dominated by humans, because it gives them a better chance of survival.1

In Montana, the species reaches its largest size, with specimens sometimes exceeding 120 cm.1

In Canada, the species is listed as a species of special concern because its numbers have steadily declined since the 1930s.1
