Here, we’ll discuss the biggest differences between cottonmouths and Florida banded watersnakes, starting with their looks. We’ll take a closer look at where each species lives, and what kind of habitat they prefer. Then, we’ll analyze their distinct behaviors, and what makes the two species unique. We’ll go over their diets, and finally, take a look at which species is venomous. By the end, you’ll know which snake you should look out for, and how to tell the two apart.
The Key Differences Between Florida Banded Watersnakes and Cottonmouths
The biggest difference between Florida banded watersnakes and cottonmouths is that Florida banded watersnakes are nonvenomous. While both snakes enjoy aquatic habitats, they also have appearance differences. Cottonmouths are heavier and have more elliptical pupils while Florida banded snakes have round pupils. Yet, these are just a few of the more notable differences between these two snakes, let’s dive into more detail below!
Florida Banded Watersnake Vs Cottonmouth: Appearance
Out of the two snakes, cottonmouths are the bigger species. While Florida banded watersnakes rarely exceed 3.5 feet, cottonmouths can grow up to four feet long. Cottonmouths are a much heavier snake too, which is evident in the relative thickness of their bodies in comparison to the body of the Florida banded watersnake. Additionally, banded watersnakes have round pupils, while cottonmouths have elliptical pupils, like a cat’s eye. And, banded watersnakes lack the heat-sensing pits behind their nostrils that mark cottonmouths as members of the pit viper family, along with rattlesnakes and copperheads. As far as coloring, both species range anywhere from yellow-brown to red-brown. Older snakes of each species tend to be darker and less vibrant. Young cottonmouths even have a bright yellow-tipped tail which they use to attract prey. The biggest difference in coloring between the two comes from their striped patterns. Florida banded watersnakes have thick, dark brown stripes, while cottonmouths have irregular, thinner bands.
Florida Banded Watersnake Vs Cottonmouth: Habitat
Cottonmouths and banded watersnakes live throughout the coastal lowlands of Florida, Georgia, South Carolina, and North Carolina. However, the cottonmouth has a much broader inland range, and can be found throughout much of the southeastern United States. The Florida banded watersnake is restricted to lowland sources of freshwater. In addition, while banded watersnakes have a greater range, the Florida banded watersnake subspecies is mostly confined to the state of Florida. Cottonmouths and banded watersnakes are semi-aquatic; they can often be found draped over branches overhanging sources of freshwater, or basking on rocks at the water’s edge. Water moccasins prefer permanent sources of water, while banded watersnakes will take any source of water they can get. These include rivers, swamps, lakes, marshes, and floodplains. The banded watersnake is almost never found away from water, while the cottonmouth can sometimes be found on dry land far from water. Both are excellent swimmers.
Florida Banded Watersnake Vs Cottonmouth: Behavior
As you might imagine, Florida banded watersnakes are extremely common in Florida and banded watersnakes are common in other southeastern states. But, cottonmouths are common too. Both species are active during the day and at night, hunting whenever they can. Other species of snake, like the Mojave rattlesnake, hibernate during the cold winter months, but neither the cottonmouth or the banded watersnake take a winter break. Both species produce up to 20 snakelings at a time, usually every 2-3 years, in the late summer or early fall. Like many species of snake, cottonmouths and Florida banded watersnakes are ovoviviparous, meaning that eggs hatch inside the female, who then gives birth to live young. Young snakes of both species tend to be more brightly colored than adults. Both adults and juveniles will strike if threatened, but aren’t overtly aggressive.
Florida Banded Watersnake Vs Cottonmouth: Diet
Cottonmouths and Florida banded watersnakes are semi-aquatic species and prey on many of the same creatures. The biggest difference in their diets is in size: cottonmouth snakes are larger and heavier than Florida banded watersnakes, meaning they can hunt bigger prey. Florida banded watersnakes eat mainly frogs, newts, salamanders, toads, crayfish, and fish. Cottonmouths eat all of those things too, especially when they’re young and small. But, once they’re big enough, they can also eat other snakes, reptiles, turtles, small mammals, and even baby alligators.
Florida Banded Watersnake Vs Cottonmouth: Venom
Out of the two species, only the cottonmouth is venomous. Cottonmouths are pit vipers, like rattlesnakes and copperheads, with venom glands located just under their eyes. The Florida banded watersnake, though frequently confused with the cottonmouth, has no venom. A bite from either will hurt, but only the cottonmouth is capable of delivering venom. Cottonmouths aren’t aggressive—they almost always bite as a last resort, or if they’re accidentally stepped on. Not all bites envenomate either, many are venomless, dry bites. When venom is used, it acts to kill small prey. In humans, cottonmouth venom can cause bleeding and tissue death at the sight of the bite. However, cottonmouth bites to people are rarely serious, though they do require a visit to the hospital.
Florida Banded Watersnake Vs Cottonmouth: Which is More Dangerous?
Without question, the water moccasin is more dangerous than the banded watersnake. Banded watersnakes may look fearsome, and they can indeed deliver a painful bite, but they lack venom, and can’t do any serious damage to humans. Cottonmouths, though they have a bad reputation, aren’t all that dangerous. Even if a cottonmouth bites you—which only happens after extreme provocation or mishandling—the bite only rarely results in serious, life-threatening complications. If you do sustain a bite from a cottonmouth, don’t attempt to kill or capture the snake. Instead, keep the bitten area below your heart, and seek medical attention. Do not ice the bite, or try to suck the venom out. Similarly, there is no need to make any incisions over the puncture wounds. Medical personnel will monitor the bite, and, if there are signs of envenomation, administer antivenom.
