The venom is a complex mixture of proteins, including enzymes such as proteases and peptidases. It is hemotoxic, meaning it damages blood and destroys tissue. It also has neurotoxic properties, meaning it attacks the nerves.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

Females often gather in communal dens to give birth and care for their young. Some females even look after unrelated young while the mothers take a break.1

Newborn snakelets measure 22 to 28 cm and are venomous from the moment they are born.1

Prairie rattlesnakes prefer a straight migration path, even in areas dominated by humans, because it gives them a better chance of survival.1

In Montana, the species reaches its largest size, with specimens sometimes exceeding 120 cm.1

In Canada, the species is listed as a species of special concern because its numbers have steadily declined since the 1930s.1
