How Big Can Water Moccasins Get


Water Moccasins are a type of venomous snake found in the southeastern United States. They can grow to be up to six feet in length, although the average size is between three and four feet. Water Moccasins have a dark brown or black body with a light-colored belly, and they are often mistaken for other types of snakes such as the Copperhead.

Water moccasins, also known as cottonmouths, are a type of venomous snake found in the southeastern United States. They can grow to be quite large, with some individuals reaching lengths of over 6 feet! Despite their size, they are relatively slender snakes with dark brown or black bodies and wide heads.

Their name comes from the white lining of their mouths, which is revealed when they open their mouths to strike. Water moccasins are aggressive snakes that will not hesitate to bite if they feel threatened. Luckily, antivenom is available for those who are unfortunate enough to be bitten by one of these dangerous creatures.

What is the Biggest Water Moccasin?

The biggest water moccasin on record was nearly six feet long and weighed over fifteen pounds. The average size for an adult water moccasin is three to four feet long.

What’S the Difference between a Water Moccasin And a Cottonmouth?

Most people tend to lump water moccasins and cottonmouths together, but there are actually some key differences between the two snakes. For one, water moccasins are a type of pit viper, while cottonmouths are not. This means that water moccasins have heat-sensing pits on their faces, which help them to locate prey, whereas cottonmouths do not have these pits.

Water moccasins also tend to be larger than cottonmouths, with an average length of 3-4 feet compared to the 2-3 foot average length of a cottonmouth. Finally, perhaps the most obvious difference is in the coloration of the two snakes – water moccasins are typically dark brown or black, while cottonmouths get their name from their light-colored mouths (the rest of their bodies can be various shades of brown). So what does this all mean?

Well, if you’re trying to identify a snake that you’ve seen in the wild, pay close attention to these key differences. If it’s a large snake with a light-colored mouth, it’s likely a cottonmouth. But if it’s a smaller snake with no pits on its face and a dark coloring, then it’s probably a water moccasin.

Either way, both snakes can be dangerous so it’s always best to err on the side of caution and give them plenty of space!

What is the Largest Cottonmouth Snake on Record?

The largest recorded cottonmouth snake was found in Louisiana and measured 7 feet, 6 inches long. The average size for a cottonmouth snake is between 2 and 3 feet long.

Are Water Moccasins Lethal?

Water moccasins, also known as cottonmouths, are a type of venomous snake found in the southeastern United States. They are considered to be one of the most dangerous snakes in North America due to their aggressive nature and potent venom. While water moccasins are not typically fatal to humans, they can cause serious medical problems if not treated promptly.

Their bites can result in severe pain, swelling, tissue damage, and even death if left untreated. If you suspect that you or someone else has been bitten by a water moccasin, it is important to seek medical attention immediately.

Water Moccasin Bite Death Time

Water Moccasin bites are incredibly dangerous and can often be fatal. The venom of a Water Moccasin is highly toxic and can cause paralysis, internal bleeding, and tissue damage. If you are bitten by a Water Moccasin, it is important to seek medical attention immediately as death can occur within just a few hours.


While it’s hard to determine the average size of a water moccasin, because they can vary so much in size, the largest one on record was almost six feet long! The majority of water moccasins are between two and four feet long, though, with the average being closer to three feet. So, if you see a snake that looks like it could be a water moccasin and it’s longer than four feet, there’s a good chance that it is.
