Did You Know?

1. The coral snake that is considered one of the most poisonous in the world is the Eastern Coral Snake (Micrurus fulvius).
2. Although it has vibrant colors, the coral snake uses its colorful bands as a warning to potential predators rather than for camouflage.
3. Coral snakes have a fixed fang, meaning they are unable to retract their fangs like other venomous snakes.
4. The venom of a coral snake largely affects the nervous system, causing paralysis, respiratory distress, and even death if left untreated.
5. Interestingly, coral snakes have a minor role in medical research due to the unique composition of their venom, which contains neurotoxins that could potentially be used to develop new medicines.


1. Harlequin Coralsnake: Identification And Venom

The Harlequin Coralsnake (Micrurus fulvius) is one of the four coral snake species found in the United States, and it is the only venomous one among the group. Its venom is highly potent and dangerous, making it a species to be cautious of when encountered in the wild.

Identifying the Harlequin Coralsnake can be quite challenging due to its resemblance to harmless mimics like the Scarlet Kingsnake and the Scarletsnake. However, there are some key features that can help differentiate it.

The Harlequin Coralsnake has a distinctive pattern consisting of brightly colored bands of red, yellow, and black rings that encircle its body. Unlike the non-venomous mimics, the order of these rings is different. As a rule, the Harlequin Coralsnake’s red bands touch the yellow bands, while the non-venomous mimics have touching red and black bands. Furthermore, the head of the Harlequin Coralsnake is black, while the mimics have red heads. It’s important to remember the famous rhyme, “Red touch yellow, kills a fellow; red touch black, venom lack,” as an aid in distinguishing the venomous coral snake from its harmless look-alikes.

The venom of the Harlequin Coralsnake is primarily neurotoxic. It affects the nervous system and can lead to respiratory failure if left untreated. Although bites are rare, they should be considered a medical emergency, and immediate medical attention should be sought if bitten. It’s crucial to exercise caution and avoid handling this species to prevent any potential harm.

2. Scarlet Kingsnake: Similarities To Coral Snakes

The Scarlet Kingsnake (Lampropeltis elapsoides) is a non-venomous snake that often causes confusion due to its similar appearance to coral snakes. It shares the same color pattern of red, yellow, and black bands as the Harlequin Coralsnake. While they resemble each other, there are distinguishing features that can help differentiate the two species.

Unlike the Harlequin Coralsnake, the Scarlet Kingsnake has a red head instead of a black one. Additionally, the order of the colored bands on the Scarlet Kingsnake is different from that of the Harlequin Coralsnake. The red and black bands touch each other, while the yellow bands are separated from them. Remembering the aforementioned rhyme can be beneficial in distinguishing the non-venomous Scarlet Kingsnake from its venomous counterpart.

  • It’s worth noting that the Scarlet Kingsnake, like other kingsnakes, is a constrictor and relies on squeezing its prey rather than venom to subdue it.
  • Despite its harmless nature, it’s essential to treat all snakes with respect and refrain from handling them unless you are trained and experienced in snake handling.

3. Scarletsnake: Distinctive Characteristics And Venom Potential

The Scarletsnake (Cemophora coccinea) is a non-venomous species that closely resembles coral snakes. Similar to the Harlequin Coralsnake and the Scarlet Kingsnake, it showcases a striking red, yellow, and black banding pattern. However, there are several distinct characteristics that differentiate it from its venomous counterparts.

Unlike coral snakes, the Scarletsnake possesses more black bands, which separate the red and yellow bands rather than touching them directly. Furthermore, the head of the Scarletsnake is predominantly black, whereas coral snakes can have either a black or red head.

It is essential to emphasize that the Scarletsnake is non-venomous and poses no threat to humans. It mainly feeds on small reptiles, amphibians, and insects. Although it might be mistaken for a dangerous coral snake, it is crucial to avoid handling any snake unless you possess the necessary expertise and experience.
