Which of these snakes is commonly found in the US?

Rattlesnakes are indeed a commonly found species in the United States. They are part of the pit viper family, recognized by their distinctive rattle at the end of their tails, which they use as a warning signal when threatened. Rattlesnakes are widespread and inhabit a variety of environments, including deserts, forests, and grasslands across the country, making them one of the most recognized snakes in the region.

While ground snakes, coral snakes, and king snakes can also be found in certain areas of the United States, they do not have the same level of distribution or recognition as rattlesnakes. Ground snakes tend to be less commonly encountered and vary by specific locations. Coral snakes are known to be venomous but are generally less frequently seen because they prefer secluded habitats. King snakes are also present and are popular due to their color variety and non-venomous nature, but they do not have the same iconic status or wide-ranging presence as rattlesnakes.
