Key identifying features

The Pygmy Coral Snake refers to several small-bodied coral snake species in the genus Micrurus or related elapid genera, identified primarily by their notably small, slender build compared to most other coral snakes, combined with fine red, black, and yellow or white banding along the body. Small overall size is the most immediately useful identification cue.

Coloration & pattern

The body displays narrow, closely spaced bands of red, black, and yellow or white, often finer and more delicate in appearance than the broader banding seen in larger coral snake species. The proportion and grouping of bands can vary by species and locality, but the overall vivid, ringed coral snake pattern is retained even at this small scale.

Head, eyes & scales

The head is small and rounded, not distinct from the neck, typical of elapids and different from the broad, triangular heads of pit vipers. The snout is often solid black. Eyes are tiny and dark. Scales are smooth and glossy.

Size & body shape

As the name suggests, this species (or species group) is notably smaller than most other coral snakes, with adults often reaching only around 12 to 20 inches, and a very slender, thread-like body.

Range & habitat where you'll see it

Pygmy coral snakes are found in parts of Central and South America, typically in forested or semi-forested habitats, often in leaf litter or under surface debris, where their small size and secretive, largely fossorial habits make them rarely encountered.

How to tell it apart from look-alikes

The combination of very small size and slender build with classic coral snake banding helps separate this species from larger coral snakes as well as from small nonvenomous banded snakes that may mimic the pattern. A solid black snout and rounded head, together with the notably thin body proportions, are useful supporting features, since band color order can vary regionally among true coral snakes and their mimics.
