Its venom is cytotoxic, which means it destroys tissue. It also contains digestive enzymes that disrupt blood flow and stop blood from clotting. In its prey, these effects cause severe internal bleeding.1

The snake is shy and avoids humans when it can. Most bites in Ontario happened after people handled it or accidentally stepped on it. Only two deaths from its bites have been recorded in Ontario, and in both cases the victims did not receive proper treatment.1

Kaj naredi, ko se prestraši?

It is shy and tends to withdraw from people rather than confront them.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.

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

Dejstva

It is a pit viper, a family that includes all rattlesnakes, and it is the only venomous snake in Ontario.1

Mothers and newborns stay together for a few days, until the young shed their skin for the first time.1

Females often do not breed every year, usually having a two-year breeding cycle.1

Its populations have declined so much that it has disappeared from many of its former areas, and now survives mainly in small, isolated groups.1
