Moellendorf's Ratsnake (Elaphe moellendorffi) is a striking species native to the forests and mountainous regions of Southeastern Asia, specifically in Guangdong and Guangxi in China, and Hòa Bình in Vietnam. This species exhibits a beautiful color pattern with reddish-brown or orange tones highlighted by dark bands, which helps it blend seamlessly into its natural habitat of dense foliage and tree branches. The vivid coloration not only provides effective camouflage but also makes the snake a visually appealing subject for herpetologists and reptile enthusiasts.

Another intriguing aspect of Moellendorf's Ratsnake is its arboreal lifestyle. This snake is adapted to climbing and navigating through trees, where it hunts for a diet that includes small mammals, birds, and lizards. Its behavior is well-suited to its environment, allowing it to use its agility and camouflage to its advantage while hunting and avoiding predators. Moellendorf's Ratsnake is noted for its generally docile nature, making it a manageable species for both study and captivity. Additionally, there is some evidence suggesting that this species may also occur in Laos, although its presence there has not been definitively confirmed.
