While running into them can occur in rural and wilderness areas, Texans have learned to coexist with these iconic reptiles.

New Mexico


The western diamondback rattlesnake, famous for its venomous bite, heat-sensing abilities, and distinctive rattle, is the most infamous serpent species in New Mexico. However, the Land of Enchantment is home to nearly ten rattlesnake species.

When Nevada comes to mind, what do you envision? Slot machines, the dazzling lights of Las Vegas, or the glitz of cowboy attire?

Sadly, the Eastern Massasauga is listed as a threatened species in Michigan. These rattlesnakes aren’t desert dwellers. They thrive in Michigan’s boggy marshes, fens, and wet meadows. Habitat loss due to the development and drainage of wetlands, their preferred home, is a primary culprit for their reduction in numbers.
