Micruroides euryxanthus, commonly known as the Sonoran coral snake, is a small, brightly colored snake native to the deserts and scrublands of the southwestern United States and northwestern Mexico. It is distinguished by its striking red, yellow, and black banding. The species is nocturnal, often hiding under rocks or in burrows during the day. Despite its potent venom, it is non-aggressive and rarely bites humans. The snake plays an important ecological role by controlling the populations of small rodents and other snakes.

Micruroides euryxanthus, commonly known as the Sonoran coral snake, is native to the southwestern United States and northwestern Mexico. It is primarily found in the Sonoran Desert, covering regions in Arizona and parts of New Mexico in the USA, as well as the Mexican states of Sonora and northern Sinaloa.

The Sonoran coral snake inhabits arid and semi-arid regions characterized by desert and scrubland environments. These areas experience hot, dry conditions with limited precipitation. The vegetation typically includes cacti, thorny shrubs, and sparse grasses. The species prefers sandy or rocky soils where it can easily burrow.

Micruroides euryxanthus is a fossorial species, meaning it spends a significant portion of its life underground. It is primarily nocturnal, emerging at night to hunt for small reptiles and amphibians, which form the bulk of its diet. Its bright coloration serves as a warning to potential predators of its venomous nature. The snake plays a role in controlling the populations of its prey species, maintaining ecological balance within its habitat.
