Key identifying features

The eastern indigo snake is one of North America's largest native snakes, easily recognized by its uniformly glossy, iridescent blue-black body and a reddish-orange to cream chin and throat. It has a robust, heavy build, a broad head, and large, smooth scales that give it a distinctive sheen in sunlight.

Coloration & pattern

The body is a deep, almost blue-black color overall, often showing an iridescent sheen when light hits the scales at certain angles. Unlike many large snakes, it lacks blotches, bands, or other bold patterning, giving it a strikingly uniform appearance. The chin and throat are typically reddish-orange, salmon, or cream colored, providing sharp contrast with the dark body and serving as a key identification feature.

Head, eyes & scales

The head is broad and only moderately distinct from the thick neck, with large, round eyes suited to its active, diurnal foraging habits. Scales are smooth and large, contributing to the glossy, polished look of the body. The chin and throat coloration extends onto the lower jaw, easily visible when the snake is viewed from below or the side.

Size & body shape

This is a large, heavy-bodied snake, among the longest native to the United States, with a thick, muscular build throughout its length. Its size alone, combined with the uniform dark coloration, makes it stand out from most other snakes in its range.

Range & habitat where you'll see it

Eastern indigo snakes are found in the southeastern United States, particularly Florida and southern Georgia, inhabiting sandhill communities, pine flatwoods, and areas near gopher tortoise burrows, which they use for shelter. They are active, wide-ranging foragers often seen moving through open, sandy habitats during the day.

How to tell it apart from look-alikes

Its large size, uniform glossy blue-black coloration without pattern, and reddish-orange throat set it apart from other dark-colored snakes such as black racers, which are more slender and lack the reddish chin. The combination of size, sheen, and throat color is highly distinctive within its range.
