Key identifying features
The Brazilian Coral Snake is identified by its striking pattern of complete rings in red, black, and white (or pale yellow) encircling the entire body, a hallmark of true coral snakes. The rings are typically arranged in repeating triads, with black rings bordered by narrow white or pale rings flanking each broader red band.
Coloration & pattern
The body shows alternating wide red bands and narrower black bands, each black band edged by thin white or pale yellow rings, creating a highly contrasting, vivid banded appearance. This pattern continues uninterrupted around the entire circumference of the body, including the belly, which is a defining trait of true coral snakes as opposed to many similarly colored mimic species. The head is generally black with minimal additional patterning.
Head, eyes & scales
The head is small and rounded, not clearly distinct from the neck, and usually solid black or very dark, sometimes with a narrow pale band just behind it. Eyes are small with round pupils. Scales are smooth and glossy, which enhances the visual impact of the bold ring pattern.
Size & body shape
This species is slender and moderately long, with adults typically ranging from about 50 to 90 centimeters. The body is uniformly cylindrical, tapering to a short tail, consistent with its fossorial and semi-fossorial lifestyle.
Range & habitat where you'll see it
The Brazilian Coral Snake inhabits forested regions, leaf litter, and moist soil across parts of Brazil and neighboring areas of South America. It is largely secretive and burrowing, spending much of its time underground or under surface debris, and is most often seen after rainfall or when disturbed from cover.
How to tell it apart from look-alikes
The complete encircling rings, including on the belly, distinguish this species from harmless mimic snakes, which often show incomplete or interrupted banding on the underside. The specific black-white-black triad flanking each red band, combined with the mostly black head, provides additional confirmation, though ring width and exact sequence can vary somewhat between individuals and populations, so overall pattern continuity around the body remains the most dependable identifying feature.
