The eastern massasauga is a small rattlesnake that lives in eastern North America, mainly around the Great Lakes. It is the only venomous snake in Ontario, Canada. It is shy and keeps away from people, but it is a protected species because its numbers have fallen sharply.1

Otrovna snaga

Ugrizi

Otrov izlazi kroz očnjake ili zube kad ugrize.

Što radi njegov otrov kad ugrize ili ubode?

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

Koliko je opasno za ljude?

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

Što radi kad se uplaši?

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

Ako ugrize

Neka osoba miruje i bude smirena, drži ugriženi ud u visini srca, skini prstenje i sve što steže i brzo je odvedi u bolnicu.

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

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
