Are all snakes venomous?

With help from ERIN ARNASON

Venomous snakes are not very common, with only 7% of snake species around the world being venomous enough to harm us. In Alberta, the prairie rattlesnake is the only snake species with venom harmful to humans. Another important thing to remember is that snakes are not aggressive by nature and are much more likely to hide than risk coming close to predators, including us humans. So, if you see a prairie rattlesnake or hear the rattle of their tail, walk away slowly and give it plenty of room to escape. Snakes are not something you should fear, as they are incredibly fascinating animals, but always make sure you respect them. Even if they are not venomous, give them space and do not pick them up!
