4 Ways to Identify a Venomous Snake
Introduction:
Venomous snakes can pose a real threat to human beings and other animals due to their venom, which can cause severe pain, organ damage, or even death. However, not all snakes are venomous. For your safety, it is essential to be able to identify whether a snake is venomous or not. Here are four ways to help you identify a venomous snake:
1. Observe the shape of the snake’s head:
Venomous snakes typically have triangular-shaped heads with a distinct and narrow neck. This characteristic is due to the presence of venom glands located behind their eyes. Non-venomous snakes, on the other hand, usually have rounded heads with no distinct separation between the head and neck.
2. Look for slit-like pupils:
Venomous snakes often have slit-like pupils, similar to those of a cat, whereas non-venomous snakes generally possess round pupils. However, this method of identification is not foolproof because certain non-venomous species also have vertical slit pupils, while some venomous snakes may have round pupils depending on their geographical location.
3. Check for the presence of heat-sensing pits:
Some of the most dangerous venomous snakes belong to the family Viperidae (such as rattlesnakes, copperheads, and cottonmouths) and Crotalinae (such as pit vipers). A unique feature among these species is the presence of heat-sensing pits located between their eyes and nostrils. These pits appear as small holes or depressions on each side of their face and allow them to detect warm-blooded prey in complete darkness. Non-venomous snakes generally do not possess such heat-sensing pits.
4. Analyze the coloration and patterns:
While some venomous snakes have distinctive colorations or patterns that serve as warning signs, many non-venomous snakes have similar markings to mimic their venomous counterparts. For example, coral snakes bear a distinct pattern of red, yellow, and black bands while the non-venomous milk snake has a similar pattern with different band sequences. A useful rhyme to differentiate the two is “Red touches yellow, deadly fellow; red touches black, friend of Jack.” However, remember that this method is not always accurate and coloration can vary among individual snakes within a species.
Conclusion:
Identifying a venomous snake is crucial for your safety, but it’s essential to remember that these guidelines are not foolproof. Different snake species may have unique characteristics based on their location and habitat. Always exercise caution around snakes and give them ample space to avoid any potential confrontation. When in doubt, it is best to consult with a local wildlife expert or herpetologist for accurate identification.
