Many snake species boast vibrant colors, and a blue tail is a particularly striking feature. But which snakes sport this captivating coloration? Identifying a snake based solely on its tail color can be tricky, as many factors influence the shade and intensity of the blue. This guide explores several snake species known for their blue tails, highlighting key characteristics to aid in identification and dispelling common myths. Remember, never handle a snake you cannot positively identify. Consult local wildlife experts or herpetologists if you encounter an unknown snake.
What Kind of Snake Has a Blue Tail?
Several snake species, particularly juveniles, display blue tails. The intensity of the blue can vary depending on age, habitat, and individual variation. Some common culprits include:
-
Eastern Ratsnake (Pantherophis alleghaniensis): Young Eastern Ratsnakes often have bright blue tails, which fade with age. These snakes are non-venomous and relatively docile. Look for a slender body, large scales, and a generally olive-brown or gray body.
-
Western Ratsnake (Pantherophis obsoletus): Similar to their eastern cousins, young Western Ratsnakes may exhibit blue tails. They vary in color and pattern more than Eastern Ratsnakes, with colors ranging from gray to brown to black.
-
Corn Snake (Pantherophis guttatus): While not always intensely blue, some Corn Snake variations might show hints of blue in their tails, particularly when young. These popular pet snakes are known for their docile nature and beautiful patterns.
-
Various Colubrids: Many other colubrid snakes (a large family of non-venomous snakes) may have blueish tinges on their tails, especially as juveniles. Proper identification requires examining additional characteristics like scale patterns, head shape, and overall body size.
Why Do Some Snakes Have Blue Tails?
The vibrant blue tail serves a crucial purpose, particularly in young snakes: predator distraction. The bright coloration attracts the attention of potential predators, allowing the snake to escape while the predator focuses on the easily shed tail. This is a survival mechanism known as caudal autotomy. Once the tail is shed, the young snake has a chance to escape and grow. As they mature, the tail color typically fades.
Is a Blue-Tailed Snake Venomous?
Not necessarily. Many non-venomous snakes, especially in the colubrid family, display blue tails when young. However, some mildly venomous species may also have blue tail elements. It is crucial never to assume a snake's venom status based solely on its tail color. Always exercise caution and seek professional identification if you encounter a snake you can't identify.
How Can I Identify a Snake with a Blue Tail?
Identifying a snake requires a holistic approach. Don't rely solely on tail color. Pay close attention to:
- Body Shape and Size: Is it slender or stout? Long or short?
- Head Shape: Is it distinct from the neck? Triangular or rounded?
- Scale Patterns: Note the arrangement and shape of the scales.
- Overall Coloration: Observe the entire body's color and pattern.
- Location: Where was the snake observed? Geographic location helps narrow down possibilities.
What Should I Do If I Find a Snake with a Blue Tail?
- Observe from a Safe Distance: Never approach or attempt to handle the snake.
- Photograph (if possible): Take a picture from a safe distance to aid in identification.
- Contact Local Experts: Reach out to wildlife officials, herpetologists, or local animal control for assistance.
Remember, responsible observation and avoidance are key to interacting safely with wildlife. Using a reputable field guide specific to your region is crucial for accurate identification.
