Massasauga Rattle Snake

Don't approach them, don't kill them, respect them and enjoy them from a distance. You are on their turf. Sistrurus catenatus (the binomial, scientific name for the Eastern Massasauga Rattlesnake) is a species at risk.


The word/adjective catenatus (Latin) is the perfect passive participle of catēnō (verb) referring to being chained or shackled. In English a descendent of catenatus in Latin means chained or chain-like and refers to the central row of dark spots on the body. Massasauga is from the Ojibwa language and means "great river-mouth" which alludes to the marshy habitat of the snake.

In August 2009 a group of us were hiking for four days on the Bruce Trail on the Bruce Peninsula. During those days we saw three adults and two youngsters. The picture below was taken on one of those days. In every case the snakes felt us coming and gave us the familiar warning but this does not always happen. Being a hike leader with some experience and having owned a cottage on the Bruce Peninsula for a few years I was familiar with this interesting animal ... watch the animal but stay a good distance away from it!

Rattlesnake Sound Listen to typical rattlesnake sound.

If anyone is bitten by an Eastern Massasauga Rattlesnake, treat it like a medical emergency. There is a section on this topic, including what to do, on the Georgian Bay Islands National Park of Canada web page. I have included a couple of Youtube videos below. I do not condone most of the behaviour in the second amateur video but it does provide some good audio of the snake rattle sound ... remember, keep your distance if you encounter one and give the snake a path to escape.
