How many poisonous snakes are in Georgia?
6 Most Dangerous Snakes in Georgia

There are 6 poisonous snakes in Georgia.

There are more than 40 snakes native to Georgia of which only 6 of them are poisonous. Familiarizing yourself with the colors and patterns of Georgia’s six deadly snake species will enable you to determine whether any snake encountered is poisonous or non-poisonous because it is illegal to kill a non-poisonous snake in Georgia.

Although the possibility of incurring a venomous snake bite should be taken seriously, only the Timber Rattlesnake, Eastern Diamondback Rattlesnake and Cottonmouth realistically represent a serious threat to human life. That risk is remote when compared to other environmental hazards, such as lightning. According to the National Weather Service, 372 deaths due to lightning were recorded in the United States from 2002-2011, or an average of 37 deaths annually.

According to the American Association of Poison Control Centers, only 20 venomous snake bites reported nationwide during the same period were fatal, an average of two fatalities a year.

1. Eastern Diamondback Rattlesnake (Crotalus adamanteus)

 Eastern Diamondback Rattlesnake (Crotalus adamanteus)

DESCRIPTION: Georgia’s heaviest-bodied and one of the state’s longest snakes, reaching or possibly exceeding 7 feet, but more typically measuring 3-5 feet in total length. The tail has 3-10 brown and white bands and a “rattle” (one or more loose rings of hard keratin) that makes a loud whirring noise when shaken. Upper surface of the body is patterned by a long row of 24-35 dark brown, diamond-like blotches, fringed by thin yellow to cream borders. These blotches are broader than long and are linked together at their tips.

HABITAT: Eastern Diamondbacks occupy upland habitats with an open canopy, especially native longleaf pine forests on sandhills, clay hills and flatwoods. Found in numbers on barrier islands, especially within inter-dune meadows containing dense bunch grasses alternating with shrub thickets and in the dense edges of saltmarsh. Also found in mixed pine-hardwood forests that develop on abandoned agricultural sites, and in and around open woodlots, brushy pasture borders and abandoned homesites in suburban and rural areas. However, these snakes almost never enter houses.

STATUS: Rare, Georgia Species of Concern. Human impacts have caused the species to decline throughout its range. Habitat loss, fragmentation and degradation are the most serious threats to the species because its upland habitats are in high demand for agriculture, silviculture, and residential development. Unfortunately, Eastern Diamondbacks are killed by most people whenever they are encountered. The widespread practice of gassing Gopher Tortoise burrows to kill rattlesnakes or evict them for use in “rattlesnake roundups” often harms this species, and is a detriment to the large assemblage of up to 300 other animal species that use tortoise burrows.

2. Cottonmouth Water Moccasin (Agkistrodon piscivorus)

Cottonmouth Water Moccasin (Agkistrodon piscivorus)

DESCRIPTION: Relatively large, heavy-bodied snakes reaching a maximum length of nearly 6 feet, but most are less than 3 feet, 3 inches. Although these snakes are characterized by wide, dark bands along the body on a lighter brown or olive-colored background, individual coloration varies within and among populations. As Cottonmouths mature, many become very dark, and the bands become totally obscured.

HABITAT: Semi-aquatic. Cottonmouths prefer swamp-like habitats and can be very abundant in these areas. Sometimes found along rivers or in more open areas such as around large lakes. Also, these snakes may move overland long distances and can sometimes be found far from any water source. They generally hibernate in dry, upland areas, often in stump holes.

NON-VENOMOUS SPECIES OFTEN CONFUSED WITH: Several species of the large watersnakes (genus Nerodia; Plain-bellied, Northern, Brown, Banded and Green) are often mistakenly referred to as Cottonmouths because of their similarity in appearance. However, the dark stripe on the side of the jaw, heat-sensing pit on the face and the behavior of gaping – a defensive posture where the snake opens its mouth wide – are distinctive to Cottonmouths.

STATUS: Abundant

3. Eastern Coral Snake (Micrurus fulvius)

Eastern Coral Snake (Micrurus fulvius)

DESCRIPTION: Fairly slender snakes reaching a maximum length of 47 inches, but most range from 20-30 inches long. The body is patterned with broad black and red rings, equal in width and separated by narrow yellow rings. The red rings are dotted with numerous black flecks that may coalesce on the back into a pair of spots. The rounded snout is black and is followed by a broad yellow band across the head and neck. The tail has three or four broad black rings and two to four narrow yellow rings.

HABITAT: Coastal Plain populations are typically associated with sandy upland habitats such as longleaf pine sandhills and pine-saw palmetto flatwoods. Live oak and other hardwood hammocks on well-drained soils may also support populations. Eastern Coral Snakes are absent from extensive wetlands and from vast tracts of pine flatwoods underlain by low, poorly-drained soils. Individuals lead highly subterranean lives and shelter in virtually any type of underground refuge, including Gopher Tortoise burrows and stump holes.

NON-VENOMOUS SPECIES OFTEN CONFUSED WITH: The Scarlet Kingsnake also has a color pattern of contrasting red, black and yellow or white rings but has a red snout, and the light-colored rings are separated from the red ones by black. The Scarlet Snake has a red, pointed snout; red back blotches that are outlined by black; and a white, unmarked belly. A helpful rhyme to distinguish Eastern Coral Snakes goes, “Red touch yellow, deadly fellow; red touch black, venom lack.”

STATUS: Rare, Georgia Species of Concern. This species is generally distributed and seemingly fairly common in the lower and middle Coastal Plain of southeastern Georgia. Its status in the Piedmont, upper Coastal Plain and in the southwestern portion of the state is poorly known.

4. Copperhead, Highland Moccasin (Agkistrodon contortrix)

Copperhead, Highland Moccasin (Agkistrodon contortrix)

DESCRIPTION: Medium-sized snakes reaching a maximum length of about 4.5 feet, but most are less than 3 feet. The background coloration is usually light brown or gray, but individuals range from rusty orange to pinkish to nearly black. This species is easily identifiable by a pattern of 10-21 dark-brown, hourglass or saddle-shaped crossbands, which are wider at the sides of the body and become narrower along the back.

HABITAT: Occur in most forested habitats but are particularly common on rocky wooded hillsides in the mountains and swamp and river edges in the Piedmont and Coastal Plain. Habitats with abundant logs, leaf litter, and rocks for cover are favored, while open habitats such as old fields and agricultural areas are generally avoided.

NON-VENOMOUS SPECIES OFTEN CONFUSED WITH: Gray Rat Snake; Eastern Rat Snake (yellow phase); Corn Snake; Northern, Brown and Banded Watersnakes; Eastern Hognose Snake.

STATUS: Uncommon to common. Copperheads are apparently more tolerant of urban development than many snake species. Populations often persist in suburban neighborhoods as long as some patches of forest remain.

5. Timber/Canebrake Rattlesnake (Crotalus horridus)

Timber/Canebrake Rattlesnake (Crotalus horridus)

DESCRIPTION: Large, heavy-bodied snakes reaching a maximum length of nearly 6 feet in the Coastal Plain and about 5 feet in the mountains, but most range from 3-5 feet in length. The background color ranges through various shades of pink, yellow, tan, gray, brown and olive to velvety black. A series of brown to black chevron-shaped crossbands (15-34) typically cross the body. The tail is black and tipped by a segmented rattle. Very dark or solid black individuals are common in higher mountains of the northeastern part of the state but are rare elsewhere.

HABITAT: Common in much of the heavily wooded country of the Coastal Plain, but in more open areas, these snakes are primarily limited to wooded stream corridors. The range is spotty on the barrier islands and along the immediate coast. In the Piedmont, distribution is highly fragmented due to habitat loss and Timber Rattlesnakes are primarily associated with heavily wooded stream corridors and small, isolated mountains. In the Georgia mountains, the distribution is somewhat localized around suitable denning sites (including root and stump holes, mammal burrows, old home sites and debris piles, and – especially in upland regions – rock crevices).

STATUS: Common (locally abundant). Common in much of the Coastal Plain but the range is highly fragmented in the Piedmont and under increasing pressure from residential development. Timber Rattlesnakes are hunted to some extent in the mountains, where in many areas they appear to have declined in recent years.

6. Pigmy Rattlesnake (Sistrurus miliarius)

 Pigmy Rattlesnake (Sistrurus miliarius)

DESCRIPTION: Smallest of the rattlesnakes, with the maximum total length reported of 31 inches, but pigmy rattlesnakes usually reach a size of 16-23 inches. The background color is usually gray or tan, but occasional individuals can be reddish or almost black in some populations. The pattern consists of a series of light-edged dark blotches or spots (22-45) on the back, as well as from one to three rows of dark spots on the sides. There may be a reddish stripe down the center of the back. The tail is tipped by a segmented rattle; however, the interlocking segments of the rattle are poorly notched compared to other rattlesnakes, and occasionally some individuals lack a rattle.

HABITAT: Found in a variety of habitats at elevations of 0-1,640 feet and ranging from dry sandhills and longleaf pine forests to wet hammocks and seasonally flooded pine flatwoods. In southern Georgia, Pigmy Rattlesnakes specifically thrive in saw palmetto thickets.

NON-VENOMOUS SPECIES OFTEN CONFUSED WITH: Eastern and Southern Hognose snakes.

STATUS: Uncommon. In some areas, population densities of these rattlesnakes are very high, while in other places Pigmy Rattlesnakes are fairly uncommon. However, this species is small and cryptic, and chances are that many individuals are overlooked.
