If you’re exploring Alabama’s diverse landscapes or simply curious about the local wildlife, understanding the different types of snakes in the state is essential. This guide covers the most common and notable snakes found in Alabama, perfect for outdoor enthusiasts, homeowners, students, or anyone interested in native wildlife. From harmless colubrids to venomous vipers, learn what makes each species unique and how to identify them confidently.
Copperhead (Agkistrodon contortrix)
The Copperhead is one of Alabama’s most recognizable venomous snakes, known for its distinctive copper-colored head and hourglass-shaped bands across its body. Typically measuring 24 to 36 inches, it favors deciduous forests, rocky hillsides, and areas with abundant leaf litter. While its venom is potent, Copperhead bites are rarely fatal thanks to effective antivenom and generally occur when the snake is accidentally provoked. Their shy nature means they prefer to avoid humans, but awareness is key for safety during outdoor activities.
Eastern Diamondback Rattlesnake (Crotalus adamanteus)
The Eastern Diamondback is the largest venomous snake in North America, reaching lengths over 8 feet. Recognizable by its bold diamond-shaped patterns along its back and a rattle at the tail’s tip, it inhabits the coastal plains and pine forests of Alabama. Despite their impressive size and intimidating appearance, they are generally shy and avoid human contact. Their venom is highly toxic, so encountering one warrants caution, especially in rural or undeveloped areas.
Timber Rattlesnake (Crotalus horridus)
The Timber Rattlesnake is a venomous species found in the wooded hills and mountains of northern Alabama. It features a yellow or brownish background with dark, chevron-shaped crossbands along its back. Usually measuring 36 to 60 inches, it prefers deciduous forests and rocky outcrops. While bites are rare, they can be serious, so maintaining a safe distance and respecting their habitat is advised. Their distinctive rattle makes them easier to identify in the wild.
Eastern Coral Snake (Micrurus fulvius)
The Eastern Coral Snake is a brightly colored, venomous snake characterized by red, yellow, and black banding that follows a specific pattern: red touching black, which is a key identification marker to distinguish it from non-venomous lookalikes. It’s generally small, averaging 20 to 30 inches, and prefers sandy soils, pine flatwoods, and pinelands. Although its venom is potent, bites are rare, and the snake’s reclusive nature means encounters are uncommon. Recognizing its distinctive coloration is crucial for safety.
Northern Cottonmouth (Agkistrodon piscivorus)
Often called the water moccasin, the Northern Cottonmouth is semi-aquatic and frequently found near lakes, ponds, and slow-moving streams. It has a thick, dark body with a broad head and a characteristic white or cream-colored lining inside the mouth, which it displays when threatened. Adults typically measure 24 to 36 inches, but some can reach 48 inches. Their venom is hemotoxic, and bites require prompt medical attention; however, they are generally shy and prefer to escape when possible.
Scarlet Snake (Cemophora coccinea)
The Scarlet Snake is a non-venomous, harmless species known for its striking red, black, and yellow banding that resembles the venomous Coral Snake but with a different pattern. It measures 12 to 24 inches and is often found under leaf litter, logs, or in loose soil in coniferous and hardwood forests. They feed primarily on small lizards and insects. Their vibrant colors make them easy to identify, and they pose no threat to humans.
Eastern Garter Snake (Thamnophis sirtalis)
The Eastern Garter Snake is one of the most common non-venomous snakes in Alabama, recognized by its slender body and a distinctive yellow or light stripe running lengthwise down its back, flanked by darker brown or black markings. Usually measuring 18 to 30 inches, it inhabits a variety of environments, including fields, forests, and wetlands. They are harmless and beneficial, helping control pest populations such as insects and small rodents.
Eastern Hognose Snake (Heterodon platirhinos)
The Eastern Hognose is notable for its upturned snout, which it uses to burrow and dig. It displays a variety of color patterns, often with blotches of brown, black, or yellow. Typically measuring 20 to 30 inches, it prefers sandy soils and open woodlands. When threatened, it may play dead or flatten its neck to mimic a cobra, but it is non-venomous and poses no real danger to humans. Its unique defensive behaviors make it a fascinating species to observe.
Black Racer (Coluber constrictor)
The Black Racer is a fast-moving, non-venomous snake known for its sleek, shiny black appearance and bright white chin. It averages 36 to 60 inches in length and thrives in open fields, forest edges, and suburban areas. This species feeds on insects, small birds, and rodents, and is beneficial for pest control. Despite its intimidating speed, it is harmless but will often flee when approached.
How to Choose
When selecting a snake to identify or learn about, consider factors such as its coloration, pattern, size, habitat, and behavior. Venomous snakes often have distinctive markings—like the coral snake’s red and yellow bands or the rattlesnake’s rattle—while non-venomous species tend to have more subdued colors and patterns. Knowing the environment where the snake was found can also help narrow down the options, as certain species prefer specific habitats like wetlands, forests, or open fields. Always prioritize safety and consult reliable identification guides or experts when in doubt.
