Which of the following snake species is NOT native to Florida?

The copperhead is the species that is not native to Florida. In the southeastern United States, the copperhead is primarily found in regions such as Virginia, West Virginia, and parts of Tennessee and Kentucky, but it does not naturally inhabit Florida's ecosystems.

On the other hand, the coral snake, water moccasin, and various species of rattlesnake are indeed part of Florida's native reptile fauna. Coral snakes are known to inhabit various habitats across Florida, while water moccasins (also known as cottonmouths) are commonly found in wetlands and are recognized for their distinctive behavior in those environments. Rattlesnakes are also widespread in Florida, with the eastern diamondback being one notable species native to the region. Understanding the distribution of these snakes is important for conservation efforts and public safety in Florida, where various unique habitats support different snake species.
