Copperheads are venomous snakes, and correctly identifying them is crucial for safety. However, several non-venomous snakes mimic the copperhead's appearance, leading to potential misidentification and unnecessary fear or harm. This article will help you differentiate between true copperheads and their look-alikes, addressing common questions and concerns.
What other snakes look like copperheads?
Several species of snakes exhibit coloration and patterns similar to copperheads, often employing Batesian mimicry—where a harmless species evolves to resemble a harmful one for protection. Some of the most common look-alikes include:
-
Eastern Hognose Snake: These snakes are masters of deception, often flattening their heads and hissing aggressively to mimic a copperhead's threat display. However, closer inspection reveals a significantly upturned snout and a more rounded body. They are non-venomous.
-
Eastern Ratsnake (especially the melanistic form): While typically gray or brown, some Eastern Ratsnakes exhibit a dark, almost black coloration with reddish-brown crossbands, creating a striking resemblance to a copperhead. Their size and body shape are often key differentiating factors; ratsnakes are typically larger and more slender. They are also non-venomous.
-
Northern Brown Snake: This snake’s coloration can range, with some individuals exhibiting patterns remarkably similar to copperheads. A careful examination of the head shape and body scales will usually reveal differences. They are non-venomous.
-
Western Hognose Snake: Similar to its eastern cousin, this species also uses mimicry to deter predators. Its upturned snout and behavior are key identifying features, helping to distinguish it from a copperhead. They are also non-venomous.
How can I tell the difference between a copperhead and a look-alike?
Distinguishing between a copperhead and its mimics requires careful observation of several key features:
-
Head Shape: Copperheads have a distinctive triangular head, broader than their neck. Many mimics have more rounded heads.
-
Heat-Sensing Pits: Copperheads, like other pit vipers, possess heat-sensing pits located between their eyes and nostrils. These pits are absent in the mimics.
-
Pupil Shape: Copperheads have elliptical pupils, while many harmless snakes have round pupils.
-
Body Pattern: While the pattern can vary, copperheads generally exhibit hourglass-shaped crossbands that are typically darker in color. The bands in mimics may be more irregular or lack the distinct hourglass shape.
-
Body Size and Shape: Copperheads are relatively stout-bodied snakes. While size can vary, comparing the observed snake to average size ranges for copperheads and potential mimics can be helpful.
-
Location: Knowing the geographic range of copperheads and their mimics in your area significantly improves identification accuracy.
Are all snakes that look like copperheads harmless?
While the snakes listed above are non-venomous, it's crucial to remember that misidentification can be dangerous. Always err on the side of caution when encountering a snake that you are unsure about. Avoid handling any snake you cannot positively identify.
What should I do if I see a snake I think is a copperhead?
If you encounter a snake you believe to be a copperhead or a look-alike, maintain a safe distance. Observe it from afar, taking note of its features to help with identification. If you need to relocate the snake, consider contacting a local wildlife rehabilitator or animal control service. Do not attempt to handle it yourself.
How common is it for snakes to mimic copperheads?
The prevalence of mimicry in snakes is a fascinating aspect of their evolution. The effectiveness of this strategy is evidenced by the number of species that have developed similar patterns and behaviors to those of venomous snakes like copperheads. This underscores the importance of learning to correctly identify both the copperhead and its mimics.
This detailed analysis aims to help you understand the nuances of copperhead identification. By carefully observing the snake's characteristics and considering its location, you can significantly reduce the risk of misidentification. Remember, safety should always be your priority.
