Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

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

Que fai cando ten medo?

It is shy and tends to withdraw from people rather than confront them.1

Datos

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
