The ridge-nosed rattlesnake is a small venomous snake with a raised ridge on the end of its nose. It lives in wooded mountains in the southwestern United States and Mexico, and it is the official state reptile of Arizona. Its bite is rarely a serious threat to people.1

Anaishi

Southwestern United States (Arizona, New Mexico) and northern Mexico, mainly in the sky island mountain region1

Amerika Kaskazini

Nyumbani

This snake is rarely found outside high-elevation habitats, especially wooded mountain ranges in the southwest. Each subspecies lives in only a few mountain ranges, so meeting one is rare.1

Urefu

30 cm hadi 60 cm (1 ft hadi 2 ft)1

Kasi ya juu

takriban km 3.3 kwa saa (maili 2.1 kwa saa)

Nchi kavu, makadirio

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its venom is largely hemotoxic, meaning it damages blood and the tissue around the bite. Because the snake is small, it injects only small amounts of venom, so its bite is not as life-threatening as that of larger rattlesnakes. A bite can still cause pain and discomfort.1

Ana hatari gani kwa watu?

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

No deaths have been documented from ridge-nosed rattlesnakes. A bite is rare, but it can still cause pain and discomfort.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

It is the official state reptile of Arizona.1

The snake's ridge is made by upturned scales on the tip of its nose, which makes it easy to recognise.1

Although it is a rattlesnake, it gives birth to live young. The babies develop inside eggs that stay within the mother until they are born.1

Kuvunja dhana potofu

Dhana potofu: Every rattlesnake bite is equally deadly.

Ukweli: This species has very low venom yields, so its bite is not as life-threatening as those of larger rattlesnakes, and no deaths have been documented.1
