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

Domov

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

Dolžina

Največja hitrost

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

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

Če ugrizne

Poškodovanca drži pri miru in ga pomirjaj, ugriznjeni ud drži v višini srca, odstrani prstane in tesne stvari ter ga hitro odpelji v bolnišnico.

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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

Razbijalec mitov

Mit: Every rattlesnake bite is equally deadly.

Resnica: 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
