Overview
The regal coral snake, also known as the variable coral snake, is a common Micrurus species across the Gulf coastal plain of Mexico into Belize and Guatemala. It shows considerable geographic variation in ring pattern across its range, which has led to several recognized subspecies.
Despite being one of the more frequently recorded coral snakes in its range, it remains secretive and fossorial, rarely encountered outside of rainy periods.
How to identify it
- Triads of black rings separated by red, bordered by narrow white or yellow rings, with pattern details varying by locality

- Variation in ring number and width across its range requires care in subspecies identification
