So if you don't have any idea what it is, how do you know it is a snake eater?. Did you see it eating one?, or did the vendor tell you it eats snakes?
Could be anything from a Mussarana to either subspecies of Black kingsnake, to a Black Racer, or lots of other types as well. They all are known to eat snakes.
Trying to be helpful here, but that is pretty vague info you must admit..LOL!
