Types of Water Snakes
Water snakes are a unique group of reptiles that have adapted to living in aquatic environments, such as rivers, lakes, and swamps. They are excellent swimmers and have specific characteristics that allow them to thrive in the water. In this article, we will explore the different types of water snakes and focus on the Northern water snake, which can be found in Maine.
Understanding True Water Snakes
True water snakes, also known as Nerodia, are a specific group of water snakes that are adapted to living in aquatic habitats. They have flattened heads, which help them swim more efficiently in the water. True water snakes also have keeled scales, which appear rough and provide better grip and traction on slippery surfaces. These snakes are excellent swimmers and are able to hold their breath for extended periods, allowing them to hunt for prey underwater.
Characteristics of True Water Snakes
Besides their physical adaptations, true water snakes have other characteristics that make them unique. They are typically non-venomous, meaning they do not possess venom to subdue their prey or defend themselves. Instead, they rely on their strength and hunting abilities to capture their food. True water snakes are also known for their diverse patterns and coloration, which can vary depending on the species and geographic location.
Water Snakes in Maine
Maine, a state known for its beautiful landscapes and abundant wildlife, is home to one type of water snake: the Northern water snake. Although there are no other true water snake species found in Maine, the Northern water snake is a common sight in the southern and central parts of the state.
Types of Water Snakes Found in Maine
As mentioned earlier, the only true water snake species found in Maine is the Northern water snake. This species has adapted to the aquatic habitats of the state and can be found in various bodies of water, such as rivers, lakes, ponds, and marshes.
The Northern Water Snake
The Northern water snake, also known by its scientific name Nerodia sipedon, is a non-venomous water snake that is native to North America. It is a medium-sized snake, with adult individuals typically growing between 24 to 42 inches in length. Male Northern water snakes tend to be slightly larger than females, and some individuals have been known to reach lengths of up to 55 inches.
Facts about the Northern Water Snake
Now that we have explored the types of water snakes found in Maine, let’s dive deeper into the specific characteristics and behaviors of the Northern water snake.
Scientific Name and Distribution
The Northern water snake, scientifically known as Nerodia sipedon, can be found throughout eastern and central North America. In Maine, this species is most commonly found in the southern and central parts of the state, where it can be seen in various aquatic habitats.
Habitat and Behavior
Northern water snakes are well-adapted to aquatic environments and can be found in rivers, lakes, ponds, and marshes. They are primarily active during the day and are often seen basking on rocks or logs near the water.
These snakes are excellent swimmers and are often observed hunting for prey underwater. They have a diverse diet, which includes fish, frogs, salamanders, and crayfish. Northern water snakes are opportunistic predators and will eat whatever they can catch and swallow, but their diet mainly consists of fish.
Size and Growth
The size of Northern water snakes can vary depending on factors such as age, sex, and habitat. Adult snakes typically grow between 24 to 42 inches in length, with males being slightly larger than females. It is not uncommon for some individuals to reach lengths of up to 55 inches.
Juvenile Northern water snakes are much smaller than adults, usually measuring between 8 to 16 inches in length. As they grow older and larger, their diet expands, and they are able to capture and consume larger prey.
Northern water snakes primarily feed on aquatic prey, with fish being a significant part of their diet. They are skilled swimmers and are capable of chasing and capturing fish underwater. In addition to fish, they also consume frogs, salamanders, and crayfish, among other aquatic animals.
Juvenile Northern water snakes tend to feed on smaller prey items, such as insects, tadpoles, and small fish, until they grow larger and can take on larger prey.
Like many other reptiles, Northern water snakes hibernate during the winter months. In Maine, where winters can be harsh and cold, these snakes seek shelter in underground burrows, crevices, or other protected areas to survive the winter.
They may begin to hibernate as early as September or October and remain in their hibernation sites until temperatures warm up in the spring. During hibernation, their metabolism slows down, and they enter a state of reduced activity to conserve energy until the weather becomes more favorable for them to become active again.
Venomous or Non-Venomous?
One common question that arises when discussing water snakes is whether they are venomous or non-venomous. The Northern water snake, along with other true water snakes, is a non-venomous species of snake. They do not possess venom glands and rely on their other physical adaptations and hunting abilities to capture prey.
While Northern water snakes are not venomous, they can be aggressive if threatened or cornered. It is always best to observe these snakes from a safe distance and avoid handling them to prevent any unnecessary conflicts.
Conservation Status and Protection
Northern water snakes are considered a species of special concern by the Maine Department of Inland Fisheries and Wildlife (MDIFW). While they are not classified as endangered or threatened, their populations are closely monitored and managed to prevent any decline in their numbers.
These snakes face various threats in Maine, including habitat loss and degradation, road mortality, and human persecution. To protect Northern water snakes, it is illegal to kill, capture, or harass them without a permit from the MDIFW. Additionally, the destruction or alteration of their habitats, such as wetlands and shorelines, is regulated by state and federal laws.
These protective measures are in place to ensure the long-term survival of Northern water snakes and to preserve their important ecological roles in aquatic ecosystems.
Encountering Water Snakes in the Wild
If you happen to encounter a Northern water snake or any other water snake in the wild, it is important to take certain precautions to ensure your safety and the well-being of the snake.
Precautions to Take
First and foremost, it is crucial to keep a respectful distance from the snake. While water snakes are generally non-venomous and not dangerous to humans, they can become defensive if they feel threatened. Approaching them too closely or attempting to handle them may result in a defensive bite.
It is best to observe water snakes from a safe distance of at least six feet, allowing them to go about their natural behaviors without interference. Do not harass or disturb the snake in any way, as this can cause unnecessary stress for the animal.
Reporting to Local Authorities
If you encounter a Northern water snake or any other water snake in Maine, it is beneficial to report your findings to the Maine Department of Inland Fisheries and Wildlife. This information can help biologists track the population and better understand the distribution and ecological needs of these fascinating creatures.
By reporting your sightings, you contribute to the conservation efforts aimed at protecting water snakes and their habitats. Remember that water snakes play important roles in aquatic ecosystems and deserve our respect and conservation efforts.
In conclusion, water snakes are unique reptiles that have adapted to thrive in aquatic environments. In Maine, the Northern water snake is the only true water snake species found. These snakes are fascinating creatures with specific adaptations that allow them to swim and hunt underwater. While not venomous, they should be observed from a safe distance and treated with respect. By following precautions and reporting sightings, we can help conserve and protect these remarkable creatures and their habitats.
