Micrurus

The genus Micrurus encompasses approximately 80 species of New World coral snakes, known for their vibrant, ringed patterns of red, black, and yellow or white. These small, venomous snakes are part of the cobra family, Elapidae, and possess a potent neurotoxic venom delivered through short, hollow fangs.1

Micrurus species are primarily found in tropical regions, ranging from the southern United States down to Argentina. Only two species inhabit the United States: the eastern coral snake (Micrurus fulvius) and the Arizona coral snake (Micruroides euryxanthus). Coral snakes often prey on other snakes and lizards. While many species are of least concern, some are listed as endangered or critically endangered. It's important to note that numerous other snakes mimic the coral snake's appearance, and rhymes used to distinguish them in the U.S. may not be reliable elsewhere.1
