Ptyas mucosa, commonly known as the oriental ratsnake, Indian rat snake,'darash' or dhaman, is a common species of colubrid snake found in parts of South and Southeast Asia. Dhamans are large snakes, growing to 2 m (6.6 ft) and occasionally even to 3 m (9.8 ft). Their colour varies from pale browns in dry regions to nearly black in moist forest areas. Dhamans are diurnal, semi-arboreal, non-venomous, and fast-moving. Dhamans eat a variety of prey and are frequently found in urban areas where rodents thrive.
