The habitat ranges of very dangerous snakes in the U.S.

I’m glad I live in the middle of the Great White North. No venomous snakes! For some inexplicable reason I had a dream about being in Florida the other night. That sounds like a good dream: Disneyworld, Miami Beach and warm temperatures. But what was odd about this dream was that I was in a semi-swampy area where there were hordes of aggressive, large poisonous snakes. It was a freaky dream, lots of running away from snakes. Having snakes crawl from under couches etc. The last I remember about the dream I was attacking some smaller snakes in a motel room with a spade.

That dream led me to research deadly snakes in the United States. The bastards are all over the place.

The Eastern Diamondback Rattlesnake.





This is a big bitch. Up to 8 feet long and 35 pounds. Some think it is the biggest pit viper in the world. Run into this thing while searching for the golf ball in the scrub and I would instantly meet the maker, and that is without getting bitten. Notice it’s throughout Florida.


Western Diamondback Rattlesnake



Very similar to the Eastern but a lot smaller. Likes the desert as opposed to it’s cousin which likes lush forested areas.


Cottonmouth, also known as the Water Moccasin






This is a nasty little bastard. The cottonmouth is one of the most feared venomous snakes in North America. Its powerful cytotoxic venom is so destructive that it can eat away flesh and result in grisly amputations. Their preference for hiding in water and attacking when least expected means that bites are also relatively frequent. Again, another deadly snake that slithers throughout Florida.






For some reason this snake avoids Florida.

The copperhead is perhaps responsible for the most bites of any snake on this list. It’s not because the snake is inherently more aggressive, but because copperheads tend to “freeze” when met with approaching humans—instead of fleeing like most other, sensible snakes—and will bite when stepped on.

The copperhead also has what is believed to be the weakest venom potency of all pit vipers, which is a happy coincidence for the snake that is otherwise most likely to bite you.


Timber Rattlesnake



I never realized there were so many rattlesnakes in the east. Florida spared again.


Coral Snakes



Eastern coral snakes are very reclusive and are rarely seen, which is great for hunters and hikers across the American Southeast. The eastern coral snake was once seen as the most dangerous snake in the region. While that reputation hasn’t exactly subsided, experts now say that fatalities from this dangerous species are actually very rare. This is thought to be because the coral snake has very little control of how much venom it can inject into a victim.


Massasauga Rattlesnake


Canada isn’t entirely left out


These pesky rattlesnakes go all the way up to the tip of southern Ontario. To the edges of Canada’s number one city Toronto, at least that is what the residents of Toronto think.


Prairie Rattlesnake



More Canadian content here. These critters crawl all the way up to Saskatchewan and Alberta. Florida is spared again!
