Species overview
About the Central American Indigo Snake
The Central American indigo snake is a large, robust snake with smooth-looking scales. Color varies, but some individuals have a lighter brownish front and a much darker rear body and tail. It should not be identified solely by being large and dark.
It uses ground-level habitat in wooded and open landscapes. The name indigo does not mean every animal is uniformly blue. Give a snake on a trail room to leave and never block its route for a photograph.
