Oriental Rat Snake in Bali

The Oriental Rat Snake, scientifically known as Ptyas mucosa and locally called Ular Tikus, is a common and harmless snake found throughout Bali. This non-venomous snake plays a crucial role in the ecosystem by controlling rodent populations, which helps in maintaining a balanced environment. It is easily identified by its smooth scales, slender body, and typically brown or olive coloration.

These snakes are diurnal, meaning they are active during the day, and are often spotted in forests, grasslands, and even near human settlements. Their presence is beneficial, especially in agricultural areas, where they help keep pest populations under control. Despite their size, reaching up to 2.5 meters in length, Oriental Rat Snakes are generally non-aggressive and will usually flee when encountered by humans. However, like most wild animals, they may bite if provoked or handled.

The Oriental Rat Snake’s adaptability to various habitats, including close proximity to humans, makes it a frequent sight in Bali. Understanding their behavior and recognizing their beneficial role can help in fostering a peaceful coexistence with these non-threatening reptiles.
