Native Florida snakes include the eastern indigo snake, common kingsnake, common gartersnake, eastern hog-nosed snake and striped crayfish snake. Florida also has six species of venomous snakes, including the eastern diamond-backed rattlesnake, timber rattlesnake, pygmy rattlesnake, copperhead and coralsnake. The cottonmouth, or water moccasin, is a venomous water snake.
Florida's native snakes inhabit most of the state's diverse habitats, including wetlands, woodlands and fields. These snakes are a source of food for many other creatures, such as alligators, birds of prey and other predators.
Florida has over 40 species of native snakes, the vast majority of these being nonvenomous. Some of these, such as the common kingsnake and eastern indigo snake, eat the venomous snakes. The state's six venomous snakes have markings that sometimes resemble those of nonvenomous species, and so special care is needed for identification. The University of Florida provides an online guide to identifying snake species within the state, including range maps that show each species' location.
A few non-native species of snakes have also made their way into Florida's ecosystems. Burmese pythons and other imports have a negative impact on native snake populations. Two types of legless lizards, glass lizards and the Florida wormlizard, are often mistaken for snakes, but belong to the lizard family.
