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

Leef in

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

Noord-Amerika

Tuis

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

Lengte

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

Topspoed

omtrent 3,3 km/h (2,1 mph)

Op land, rowwe skatting

Wat eet dit?

It is an ambush hunter that coils and waits for prey to come within striking range. It eats small mammals, birds, lizards and large centipedes. Young snakes mostly eat centipedes and lizards, while adults mostly eat mammals and birds.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

No deaths have been documented from ridge-nosed rattlesnakes. A bite is rare, but it can still cause pain and discomfort.1

As dit byt

Hou die persoon stil en kalm, hou die gebyte arm of been op hartvlak, haal ringe en stywe goed af, en kom vinnig by 'n hospitaal uit.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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

Mite-breker

Mite: Every rattlesnake bite is equally deadly.

Waarheid: 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
