The Mexican pygmy rattlesnake is a small, venomous pit viper. It lives in the mountains of central and southern Mexico, and nowhere else in the world. Its venom and its rattle make it a useful animal to learn to recognise.1

Jinsi ya kumtambua

Moderately stout in build1
Large parietal scales on top of the head, which vary a lot in shape1
Usually 21 scales around the middle of the body (in the nominate subspecies, C. r. ravus)1
Usually 2 to 4 bands on the tail (in the nominate subspecies, C. r. ravus)1
A relatively large rattle (in the nominate subspecies, C. r. ravus)1

Mara nyingi huchanganywa na: It is closely related to Crotalus triseriatus, Crotalus pusillus, Crotalus aquilus and Crotalus lepidus, which form a species complex with it.1

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

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

It has three recognised subspecies, and genetic studies show strong differences between them that match geographic barriers.1

A genetic study using nuclear markers places it at the base of its species complex, meaning it is the earliest branch among its close relatives.1
