In this article, we will address all of the key differences between cottonmouths and copperheads, including their preferred habitats and how they appear. This may help you better identify them should you happen to stumble upon one in the wild. Let’s get started and learn how to tell these two snakes apart!
Comparing Cottonmouth vs Copperhead
The Main Differences Between Cottonmouth vs Copperhead
There are many key differences between a cottonmouth vs copperhead. While both of these snakes are considered venomous, cottonmouths are widely considered to be more venomous than copperheads are. The snakes also prefer different habitats, and their coloring and appearances differ from one another as well. However, it can be hard to tell the difference between these two snakes if you have an untrained eye. Let’s discuss the differences between these two snakes now.
Cottonmouth vs Copperhead: Size and Species
While cottonmouths and copperheads belong to the same genus and family of snakes, there are some key differences in their overall size. For the most part, cottonmouths are largely considered to be bigger than copperheads. These snakes are both wider and longer than copperheads are, sometimes to an extreme degree. For example, the average cottonmouth grows anywhere from five to 50 inches in length, while the average copperhead tends to stop growing anywhere from 20 to 35 inches in length. Cottonmouths also have a much wider body than copperheads do.
Cottonmouth vs Copperhead: Location Found
Another difference between cottonmouths and copperheads is where they are typically found. These snakes are located throughout the majority of the United States, and sometimes these snakes can be found in the same geographical area. However, there are some key locations where they are likely to be found. Cottonmouth snakes are often discovered in the southeastern United States, particularly throughout Florida and Texas. This is different from copperheads when you consider that copperheads stretch as far as Southern New England and into northern Mexico. However, copperheads are also found throughout the Southern United States, just like cottonmouths.
Cottonmouth vs Copperhead: Habitat
The preferred habitats of cottonmouths differ from copperheads. While copperheads tend to prefer environments that are warm and dry, cottonmouths are usually found near bodies of water. Cottonmouths are also known as water moccasins. The nickname “water moccasin” came from its dark tan, brown, or black skin that has a pattern of dark brown or black crossbands which resemble the leather stitches of moccasin shoes. Also, cottonmouths are the only venomous water snakes in North America. Both cottonmouths and copperheads are versatile in their environmental adaptations, but cottonmouths are often known for their aquatic behavior. They tend to spend their time in marshy environments and wetlands, while copperheads prefer mountainous or wooden areas. Copperheads can also be found in suburban areas, but often in locations that offer them protection, such as wood piles or construction sites. However, as previously mentioned, cottonmouths and copperheads can be found in the same locations, including their preferred habitat. Cottonmouths will retreat to dryer land and protection should their wetlands or marshlands dry up during the warmer months of the year.
Cottonmouth vs Copperhead: Appearance
Another key difference between a cottonmouth versus copperhead lies in their overall appearance. Cottonmouths are less intricately patterned and colored when compared to copperheads, though it can be extremely difficult to tell these two snakes apart when they are young. Copperheads tend to maintain the same coloring and patterns as they age, while cottonmouths become more plain as they age. Just as their namesake implies, copperheads are often found in copper and reddish coloring, particularly their triangle heads. Cottonmouths may also be found in a tan color with dark banding, but they tend to become darker in color as they age. However, cottonmouths may be identified from copperheads by looking closely at their eyes. This is because most cottonmouths have a distinct band or stripe across their eyes, while copperheads do not. Another difference between these two snakes, should you get close enough, is that cottonmouths have white mouths while copperheads have pink mouths. However, we do not recommend getting that close to either of these snakes!
Cottonmouth vs Copperhead: Venom Strength
A final difference between cottonmouths and copperheads lies in the strength of their venom. Copperheads are largely considered to be less venomous than cottonmouths, and some studies show that you may not need antivenom if you are bitten by a copperhead. However, you should always be cautious when dealing with any sort of snake, as any snake bite will be painful, whether or not it is venomous. Both the cottonmouth and copperhead have reputations for being aggressive snakes, but neither will typically seek out to bite humans or pets. Rather, they will both defend their ground if they feel they’re in danger. As with most wildlife, give copperheads and cottonmouths their space, and they will typically leave you alone as well.
