The Mexican west coast rattlesnake is a large venomous pit viper. It lives on the coastal plain of western Mexico. It is one of the largest rattlesnakes in the world, so its size and its strong venom make it one to respect.1

Its habitat is mostly tropical thorn forest, extending into tropical deciduous forest. Around Colima, where it is particularly plentiful, the land is mostly treeless with short grass, scattered mesquite, acacias, thorny bushes and many large cacti. In the lowlands, most specimens are found crossing roads at night.1

Brown or grey body with 26 to 41 dark, diamond-shaped blotches that have light edges.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Its venom is highly toxic and is produced in large amounts. The venom contains proteases, which are enzymes that break down proteins. In some populations, it may also contain a component related to Mojave toxin.1

Ana hatari gani kwa watu?

Hatari kwa watu: Hatari sanaAnaweza kumuua mtu asiyepata matibabu.

Large specimens should be regarded as very dangerous. An average venom yield of 297 mg of dried venom has been recorded.1

Habari njema: madaktari wana dawa (ya kuzuia sumu) au matibabu ya hili.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
