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 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

Hoe gevaarlik is dit vir mense?

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

Wat doen dit as dit bang is?

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