Table of Contents

Can snakes bite underwater? In this article, we’ll discover the truth behind this popular question and delve into the fascinating world of snake behavior as we uncover the facts and dispel the myths surrounding their underwater biting abilities. Gain valuable insights and knowledge about snakes in aquatic environments in this informative post.

Overview of aquatic snake species

Aquatic snake species encompass a diverse group of reptiles specially adapted for life in water. These snakes have evolved various anatomical and behavioral characteristics to thrive in aquatic environments such as rivers, lakes, and coastal regions. They display remarkable swimming abilities, aided by their streamlined bodies and paddle-like tails, which enable efficient propulsion through water. Some well-known aquatic snake species include sea snakes, water moccasins, mud snakes, and various types of water cobras. These snakes have specialized adaptations for aquatic hunting, such as flattened tails for improved maneuverability, valves in their nostrils to prevent water intake, and the ability to hold their breath for extended periods. 

Can Snakes Bite Underwater? 


If you’re interested in swimming and scared of being bitten by snakes, you probably want to discover this query. 

Yes, snakes can bite you underwater, but usually only if they’re provoked or feel threatened. Contrary to popular belief, snakes are not restricted from biting in aquatic environments. While water resistance and buoyancy can pose challenges to their striking accuracy and range, they possess flexible jaws that allow them to open their mouths wide and deliver a bite even when submerged. 

However, the striking speed and accuracy may be reduced underwater due to the resistance and limited visibility. Additionally, certain snake species may exhibit defensive behaviors other than biting when submerged, such as swimming away or hiding. 

What Happens If A Water Snakes Bite You? 


If you are bitten by a water snake, the effects and severity of the bite can vary depending on the species and individual snake. While not all water snakes are venomous, some species possess mild venom that may cause localized symptoms such as pain, swelling, and redness at the site of the bite. 

In most cases, the effects are similar to a non-venomous snake bite and can be managed with basic first aid measures. However, it is important to seek medical attention to ensure proper evaluation and treatment. Regardless of venomous or non-venomous species, any snake bite should be taken seriously and considered a medical emergency until assessed by a healthcare professional. Prompt medical care helps to minimize potential complications and ensures appropriate treatment based on the specific circumstances of the bite.

Common Snakes That Can Be Found Underwater

Besides sea-snakes, several snake species are commonly found in underwater environments, showcasing their remarkable adaptations for aquatic life. Hydrophiinae, are fully adapted to marine habitats and are excellent swimmers. Water moccasins, also known as cottonmouths (Agkistrodon piscivorus), are venomous snakes that often reside near bodies of water such as swamps, marshes, and streams. Water cobras (Naja annulata), found in parts of Africa and Asia, are skilled swimmers and can be seen near rivers, lakes, and wetlands. Green anacondas (Eunectes murinus), the largest species of snake, are semi-aquatic and dwell in South American swamps, rivers, and flooded forests. 

What Should We Do To Deal With Snakes In Water? 

When encountering snakes in water, it is important to approach the situation with caution and respect for both your safety and the well-being of the snake. Here are a few guidelines to help deal with snakes in water: 

  • Maintain Distance: Remember that snakes typically prefer to avoid confrontation and will likely retreat if they feel threatened. So you should keep a safe distance from the snake to avoid provoking it.
  • Avoid Aggressive Actions: Do not attempt to handle or provoke the snake in any way. Avoid splashing, making sudden movements, or throwing objects at the snake, as this may agitate it.
  • Give Space: Allow the snake an escape route if it appears trapped or cornered. Clear the area and create a path for the snake to retreat without feeling threatened.
  • Observe from a Safe Distance: If you wish to observe the snake, do so from a safe distance using binoculars or a camera with a telephoto lens. This allows you to appreciate their natural behavior without disturbing them.
  • Seek Professional Help: If the snake poses a potential threat or if you are unsure about its species or behavior, it is best to contact local wildlife authorities, snake experts, or animal control for assistance and guidance.

What to do if you see a snake while swimming in a lake?

If you spot a snake while swimming in a lake, here’s what you should do:

  1. Stay calm and avoid sudden movements.
  2. Slowly back away and give the snake space to retreat.
  3. Don’t touch or provoke the snake.
  4. Safely exit the water, keeping an eye on the snake’s location.

  6. Report the sighting to authorities if necessary.

Do snake bites underwater have the same venomous effects as bites on land?

Snake bites underwater can have similar venomous effects as bites on land, depending on the species of snake and its venom composition. The severity of the venom and the resulting symptoms can vary among different snake species. While some venomous snakes possess venom that is equally potent underwater, the dynamics of the bite and the delivery of venom may be affected by water resistance and the limited visibility underwater. 


In conclusion, the question of whether snakes can bite underwater has been explored, revealing intriguing facts about snake behavior. While water resistance and limited visibility underwater can impact their biting ability, snakes have adaptations that allow them to bite effectively in aquatic environments. Certain snake species, such as sea snakes and water moccasins, are specifically adapted for life in water. It is important to exercise caution and respect when encountering snakes in water, maintaining a safe distance and avoiding provocation. Whether a snake bite occurs underwater or on land, prompt medical attention is crucial.
