Indian Rat Snake


Likely to become endangered in the near future


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. Typical mature total length is around 1.5 to 1.95 m though specimens exceeding 2 m are not uncommon. The record length for this species was recorded as 3.7 m, second in size perhaps only to their cousin Ptyas carinata among all known living colubrid snakes. Despite their large size, oriental ratsnakes are usually quite slender with even a specimen of 2 m commonly measuring 4 to 6 cm only around in diameter. Furthermore, the average weight of ratsnakes caught in Java was around 877 to 940 g, though larger males of over 2.3 m may easily weigh over 2.5 kg (5.5 lb). 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.
