FWC: 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.

This page lists 55 snakes: 53 from FWC's Checklist of Florida's Amphibians and Reptiles, Suborder Serpentes and 2 named in other official sources. 6 are venomous by official accounts: Eastern or Harlequin Coralsnake, Florida Cottonmouth, Eastern Copperhead, Eastern Diamond-backed Rattlesnake, Timber Rattlesnake or Canebrake Rattlesnake and Pygmy Rattlesnake. 5 are nonnative. FWC gives a total of 44; the 55 here are the snakes official sources name one by one.

Eastern Copperhead

Agkistrodon contortrix

Venomous per FWC

Danger to people
“Copperhead bites are extremely painful but rarely life-threatening for healthy adults and for most large or medium-sized pets.” Florida Museum of Natural History
Size
Adults usually about 2 to 3 feet (24-36 in); record about 53 inches.
How to recognize it
  • Vertical (cat-like) pupils and a heat-sensing pit between eye and nostril
  • Heavy-bodied; keeled scales
  • Head shape alone is not a reliable way to identify copperheads
Where in Florida
In Florida, copperheads occur only in the Panhandle, primarily in the western tip and along the Apalachicola River and its tributaries … Florida Museum of Natural History
What the sources say

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)

Range: In Florida, copperheads occur only in the Panhandle, primarily in the western tip and along the Apalachicola River and its tributaries. The herpetology collection at the Florida Museum contains verified records from Calhoun, Escambia, Gadsden, Jackson, Liberty, Okaloosa, and Santa Rosa counties. The range may extend to other nearby areas, but there are no confirmed records from other Florida counties.

Habitat: The Eastern Copperhead's preferred habitats in Florida are upland pine and hardwood forests with abundant leaf litter and in forests adjacent to low, wet areas boarding swamps, stream beds, river bottoms, and damp ravines. Large logs and piles of debris and rocks are often used as shelters. This species is occasionally found in suburban neighborhoods where development encroaches into favorable habitats.

What the sources say

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)

Range: Eastern Diamond-backed Rattlesnakes are found throughout Florida and in every county.

What the sources say

Venom: “Non-venomous. Striped swampsnakes are not dangerous to people or pets.” (Florida Museum of Natural History)

Habitat: Striped Swampsnakes are highly aquatic and inhabit a variety of slow-moving waterways such as cypress strands, sawgrass prairies, swamps, canals, sphagnum bogs, and flooded stands of Melaleuca trees. These snakes prefer areas with dense vegetation such as hyacinth-choked waterways, where they live and hide within the submerged roots. These secretive snakes are rarely encountered away from water, but they can sometimes be found under logs or debris near water, in crayfish burrows, or crossing roads during or after heavy rains.
