The Mountain Sipo is a long and slender snake from South America. It lives in mountain forests and moves quickly along tree branches in search of prey.
The Mountain Sipo helps maintain balance in the forest by eating lizards and frogs. It differs from related snakes by living at high altitudes in the mountains and having a very slender body.
Immature form that undergoes metamorphosis before adulthood.
