The Western rattlesnake is a venomous pit viper that lives across western North America, from the Baja California Peninsula in Mexico to the southern interior of British Columbia in Canada. It is one of only three rattlesnake species still found in Canada, which is why its populations there matter.1

Kako jo prepoznaš

  • Ground colour is dark brown, dark grey, olive-brown, or sometimes black or pale yellowish.1
  • Large dark blotches run along the back, with uneven white edges, and are wider than the gaps between them.1
  • A dark brown stripe with a white border runs from the eye to the angle of the jaw.1
  • The belly is pale yellow, usually with brown spots.1
  • Juveniles have clearer patterns that fade as the snake matures. The last two tail rings, at the base of the tail, are usually black.1

Moč strupa

Ugrizi

Strup pride ven skozi strupnike ali zobe, ko ugrizne.

Kaj naredi njen strup, ko ugrizne ali piči?

Its venom is both hemotoxic, meaning it damages blood and tissue, and neurotoxic, meaning it affects the nerves. In prey, it can cause paralysis, which stops the animal escaping. In people it is linked with cardiovascular effects, internal bleeding and headaches.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.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

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

3

It makes seasonal migrations between winter and summer habitats to follow its prey.1
