The scarlet snake and the coral snake are easily confused, and for good reason: they share strikingly similar coloration patterns. This resemblance is a classic example of mimicry in nature, where a harmless species (the scarlet snake) evolves to look like a dangerous one (the coral snake) to deter predators. However, knowing the key differences is crucial, not only for identification but also for safety. This guide will help you distinguish between these two snakes and answer some common questions.
What is the difference between a scarlet snake and a coral snake?
The most reliable way to differentiate a scarlet snake from a coral snake lies in their color banding patterns. While both species display red, yellow/white, and black bands, the arrangement of these bands is the critical distinction. Remember this simple rhyme: "Red on yellow, kill a fellow; red on black, venom lack."
-
Coral Snake (Venomous): Coral snakes have red bands adjacent to yellow/white bands, with black bands separating them. Think: red-yellow-black-red-yellow-black etc. This pattern repeats along the snake's body.
-
Scarlet Snake (Non-venomous): Scarlet snakes have red bands adjacent to black bands, with yellow/white bands separating them. The pattern is red-black-yellow-red-black-yellow, etc. This is the key difference.
It's crucial to emphasize that this rhyme isn't foolproof for all geographic variations of these species, and caution should always be used when encountering any snake. There are regional variations in coloration, and some subspecies might exhibit slight differences. Always prioritize a safe distance and professional identification if you are unsure.
How can I tell the difference between a scarlet snake and a coral snake at a glance?
While the banding pattern is the most reliable method, there are other subtle differences you can look for:
- Head Shape: Coral snakes generally have a smaller, more rounded head, while scarlet snakes can have a slightly broader, more distinct head. This is a less reliable method, however.
- Size and Build: Coral snakes tend to be slightly larger and more robust than scarlet snakes. Again, this is not always a definitive difference.
- Location: Knowing the geographic range of each species within your area can help narrow down the possibilities.
What are the common habitats of scarlet snakes and coral snakes?
Both species have specific habitat preferences:
-
Scarlet Snake: These non-venomous snakes are found in a variety of habitats, including sandy areas, pine forests, and grasslands. They are primarily terrestrial (ground-dwelling).
-
Coral Snake: Coral snakes prefer habitats with loose soil, such as sandy areas, and often are found in or near wetlands and forests. They may also be found under rocks and logs.
Are scarlet snakes poisonous?
No, scarlet snakes are not poisonous. They are harmless to humans and pose no threat. Their mimicry of coral snakes is a purely defensive strategy.
Are coral snakes dangerous?
Yes, coral snakes are venomous. Their venom is neurotoxic, meaning it affects the nervous system. While coral snake bites are relatively rare, they can be extremely dangerous and require immediate medical attention. If bitten by a coral snake, seek professional medical help immediately.
What should I do if I see a scarlet snake or a coral snake?
- Observe from a safe distance: Do not attempt to handle either snake.
- Take a picture (if possible): A photograph can be helpful for later identification.
- Leave the snake undisturbed: Allow it to continue its natural behavior.
