Florida’s diverse landscapes are home to 44 to 50 native snake species, representing a significant portion of the total snake diversity in the United States. These reptiles are found across the state. Most are not harmful to humans and play an important role in maintaining ecological balance.
Snakes help manage rodent populations, which can impact crops and carry diseases. Non-venomous snakes also prey on venomous ones. Even venomous species have roles, such as some rattlesnakes consuming ticks.
Florida’s Venomous Species
Florida is home to six venomous snake species: five pit vipers and one elapid. These are the Eastern Diamondback Rattlesnake, Timber Rattlesnake, Pygmy Rattlesnake, Cottonmouth, Southern Copperhead, and the Eastern Coral Snake. Understanding their characteristics is important for safe identification.
The Eastern Diamondback Rattlesnake is North America’s largest venomous snake, typically 3.9 to 7.9 feet long. It has a heavy body with distinctive diamond-shaped patterns outlined in yellow or cream, and a prominent rattle. They are often found in dry pinelands, scrub habitats, and coastal hammocks.
Timber Rattlesnakes, also known as Canebrake Rattlesnakes in Florida, generally measure 3.3 to 5.9 feet. They have a muscular body with gray-yellowish scales and black chevron-like bands or diamond patterns. These snakes prefer forested areas, particularly in northern Florida, and often hide near fallen logs.
The Pygmy Rattlesnake is a smaller species, usually 1.6 to 2.3 feet long. It has light gray scales with dark, often reddish, spots or bands along its back, and a very small, barely audible rattle. Pygmy Rattlesnakes inhabit various environments, including pine flatwoods, prairies, and suburban areas.
Cottonmouths, also called Water Moccasins, are semi-aquatic snakes ranging from 2.5 to 5 feet. Their coloration can vary from dark brown or black to olive, often with darker bands that become less distinct with age. When threatened, they display the white interior of their mouth. These snakes are commonly found near bodies of water such as swamps, marshes, and ponds.
The Southern Copperhead is less common in Florida, primarily found in the panhandle region. These snakes are typically 2 to 3 feet long and are recognized by their hourglass-shaped, copper-colored bands against a lighter background. They prefer wooded areas, rocky outcrops, and stream edges.
The Eastern Coral Snake is distinct from pit vipers due to its fixed fangs and bright, alternating red, yellow, and black bands. Its red bands are bordered by yellow, which helps distinguish it from non-venomous mimics. These slender snakes grow 1.7 to 4 feet long and inhabit various habitats, including pine forests and suburban gardens.
Common Non-Venomous Residents
Florida has an extensive non-venomous snake population, with many species frequently encountered. These snakes are harmless to humans and contribute positively to the ecosystem. Recognizing common non-venomous species can help reduce unnecessary apprehension.
Black Racers are among Florida’s most common snakes, known for their uniform black scales and swift movement. They can reach lengths of up to 6.2 feet and are often seen in open fields, gardens, and wooded areas. These active snakes primarily prey on rodents, lizards, and other small animals.
Corn Snakes are popular due to their striking orange, red, and brown patterns, often outlined in black. They typically grow 2 to 5 feet long and are skilled climbers, found in barns, abandoned buildings, and forested areas. Corn Snakes are constrictors that primarily feed on rodents and birds.
King Snakes, such as the Eastern King Snake, have glossy black bodies with narrow yellow or white bands, growing up to 6 feet. They are powerful constrictors that consume a variety of prey, including other snakes, even venomous ones. These snakes are often found in forests, fields, and suburban areas.
Garter Snakes are relatively small, typically 2 to 3 feet long, and exhibit diverse patterns, often with stripes running down their bodies. They are adaptable and found in many habitats, including suburban lawns, wetlands, and woodlands. Garter Snakes primarily feed on amphibians, earthworms, and small fish.
Florida Water Snakes, like the Banded Water Snake, are robust and often confused with Cottonmouths due to their aquatic habits and patterned bodies. They grow 2 to 4 feet long and have dark spots or bands on a lighter background. These non-venomous snakes are found near rivers, lakes, and ponds, feeding on fish and frogs.
General Identification Tips
Identifying snakes from a safe distance involves observing several general features rather than relying on a single characteristic. Always maintain a respectful distance from any snake you encounter. Observing its overall appearance and behavior can provide clues.
Note the snake’s body shape and size. Venomous pit vipers in Florida tend to have stout bodies and broad, triangular heads distinct from their necks, though this can be less apparent in younger snakes. Non-venomous snakes often have more slender bodies and heads not significantly wider than their necks.
Examine the pupil shape. Most venomous pit vipers in Florida have elliptical pupils resembling a cat’s eye, while non-venomous snakes typically have round pupils. However, the Eastern Coral Snake, which is venomous, also has round pupils, making this a less reliable standalone feature.
Observe the scale patterns and coloration, but understand that these can vary within species and across geographic regions. Some non-venomous snakes mimic the patterns of venomous ones, such as the Scarlet Kingsnake resembling the Eastern Coral Snake. Focus on the arrangement of colors, like the specific red-on-yellow banding of the Eastern Coral Snake.
Pay attention to the snake’s behavior. Many snakes, both venomous and non-venomous, will try to escape when approached. Defensive behaviors, such as coiling, hissing, or vibrating their tails (even if they lack a rattle), are common and do not automatically indicate a venomous species.
Coexisting with Florida’s Snakes
Encounters with snakes are common in Florida’s diverse natural and residential areas. Promoting coexistence involves understanding snake behavior and implementing strategies to minimize unwanted interactions. Maintaining a respectful distance is always the primary safety measure.
If a snake is encountered, leave it undisturbed. Never attempt to handle, harass, or kill a snake, as most bites occur when people try to interact with them. Snakes typically bite only when they feel threatened or are cornered.
To deter snakes from around homes, keep yards tidy by regularly mowing grass, clearing brush piles, and removing debris like logs, rocks, and leaf litter. These actions reduce potential hiding spots and food sources for snakes and their prey. Sealing cracks and openings in foundations and around pipes can also prevent snakes from entering structures.
Snakes play a beneficial role in controlling rodent populations, which can be a nuisance around homes and agricultural areas. Their presence indicates a healthy ecosystem. Understanding their ecological contributions can foster a more appreciative perspective toward these reptiles.
Should a snake need to be removed from an undesirable location, such as inside a home, contact a professional wildlife removal service or your local animal control. These experts have the training and equipment to safely relocate snakes without harming the animal or posing a risk to people.
