Of course the picture of crocodile here is from google and photoshop brought it to Wangdue but there are rumor of sighting of crocodile in the Punatshangchu. I wonder if it can survive in the chilly glacier water but people say once there was a group of them in Punakha, later washed away by the '94 flood. Thus, there is a possibility.
The Indian labourers seem to have seen it.
So far it existence is not confirmed and it has not posed any threat to lives of people and animal but if it is really there then it is necessary for everybody to know. The concern body, perhaps RSPN should confirm it and take necessary precautions to safe the reptile from people and people from the reptile. Meanwhile I am always ready with the camera, let's see if I am lucky enough to be the first to photograph it without being eaten.
