The night stream snake is a small snake that lives in the tropical forests of Madagascar. It is active only at night and stays near streams and damp places.
The night stream snake differs from related species by its nocturnal lifestyle near water and special coloration that helps hide in the forest. It is important for nature because it regulates the population of frogs and lizards in Madagascar's forest streams.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
