Venom: “Only six of Florida's 44 snake species are venomous: the eastern coral snake, the southern copperhead, the cottonmouth, the eastern diamondback rattlesnake, the timber rattlesnake, and the dusky pygmy rattlesnake.” (FWC)
Habitat: Harlequin Coralsnakes occupy a variety of habitats, from dry, well–drained flatwoods and scrub areas to low, wet hammocks and the borders of swamps. They are secretive and are usually found under debris and in the ground. Occasionally they are found in the open, and they have even been seen climbing the trunks of live oaks. This species is occasionally found in suburban neighborhoods where development encroaches into favorable habitats. (Florida Museum of Natural History)
