Mississippi is home to a diverse range of snake species, from harmless garter snakes to potentially dangerous rattlesnakes. Whether you’re a hiker, a homeowner, or just curious about the local wildlife, understanding the different types of snakes in Mississippi can help you stay safe and appreciate these creatures. This guide covers the ten most common snake species found in the state, providing detailed descriptions to help you identify and learn about each one.
Copperhead (Agkistrodon contortrix)
The Copperhead is one of Mississippi’s most recognizable venomous snakes, known for its distinctive copper-colored head and hourglass pattern on its body. Typically measuring 2 to 3 feet long, it prefers deciduous forests, rocky hillsides, and areas with abundant leaf litter. While its venom is potent, bites are rarely fatal thanks to prompt medical treatment, but it’s best to avoid provoking them. Copperheads are beneficial predators, controlling rodent populations naturally.
Cottonmouth (Agkistrodon piscivorus)
Also called water moccasins, Cottonmouths are semi-aquatic snakes found near lakes, rivers, and swamps in Mississippi. They grow up to 3.5 feet in length and have a thick, muscular build with a dark, banded pattern. When threatened, Cottonmouths may open their mouths wide to reveal a white interior, which is how they earned their name. Their venom can cause pain and tissue damage, so caution is advised around water bodies where they reside.
Timber Rattlesnake (Crotalus horridus)
The Timber Rattlesnake is a large, venomous species that inhabits the wooded areas of northern Mississippi. Reaching lengths of up to 4 feet, it is easily identified by its yellow and black banding and distinctive rattle on its tail. While generally shy, they will rattle to warn potential threats. Their venom is neurotoxic and hemotoxic, making bites serious but rare due to their tendency to avoid humans.
Eastern Brown Snake (Pseudonaja textilis)
Although more common in Australia, the Eastern Brown Snake has been occasionally reported in Mississippi as an invasive species. It’s a slender, fast-moving snake with a uniform brown coloration and can reach 4 feet long. Its venom is highly toxic, capable of causing serious injury or death if untreated. Due to its rarity, encounters are uncommon, but it’s important to be aware of its presence if spotted.
Eastern Diamondback Rattlesnake (Crotalus adamanteus)
The Eastern Diamondback is the largest venomous snake in North America, often exceeding 6 feet in length. It’s characterized by its distinctive diamond-shaped pattern along its back and a broad head. Found in the coastal plain and pine forests of southern Mississippi, it prefers dry, sandy habitats. Its venom is potent, and bites require immediate medical attention, making awareness and caution crucial when in its range.
Western Rat Snake (Pantherophis obsoletus)
The Western Rat Snake is a non-venomous, highly adaptable species that often reaches 4 to 6 feet long. It features a shiny black or gray body with a yellow or orange belly and is frequently seen climbing trees or basking in the sun. These snakes play a key role in controlling rodent populations and are harmless to humans. They are often mistaken for venomous snakes but pose no threat when left undisturbed.
Black Racer (Coluber constrictor)
The Black Racer is a fast-moving, non-venomous snake that can grow up to 4.5 feet long. Its sleek, solid black appearance and white chin make it easy to identify. Common in open woods, fields, and suburban areas, it is known for its agility and speed. The Black Racer is harmless and beneficial, feeding primarily on insects, lizards, and small rodents.
Eastern Garter Snake (Thamnophis sirtalis)
The Eastern Garter Snake is one of the most widespread and familiar snakes in Mississippi, measuring about 2 to 3 feet long. It has a distinctive pattern of yellow or greenish stripes running lengthwise along a brown or black body. These snakes are harmless and often found in gardens, grasslands, and near water sources. They help control pests and are a common sight in suburban yards.
Ring-necked Snake (Diadophis punctatus)
The Ring-necked Snake is a small, non-venomous species, typically less than 2 feet long, with a distinctive yellow or orange ring around its neck. Its dark, glossy body makes it easy to identify. Preferring moist environments like leaf litter and under logs, it feeds on small invertebrates and salamanders. Its shy nature and attractive appearance make it a favorite among nature enthusiasts.
How to Choose
When selecting a snake to observe or keep as a pet, consider factors like size, venom toxicity, temperament, and habitat needs. For outdoor safety, identifying whether a snake is venomous or non-venomous is crucial—most non-venomous species like rat snakes and garter snakes pose little threat. If you’re interested in keeping a snake as a pet, opt for species like the Western Rat Snake or Ring-necked Snake, which are hardy and easy to care for. Always prioritize safety and proper identification to avoid dangerous encounters.
