Good to hear that the survey was conducted in several parts of Odisha. I remember when I first photographed a dolphin in Chilika in 1995, people were surprised and didn't believe that it is from Chilika. The enlarged scope of the dolphin should help in increasing the awareness levels among people and bring attention to this much maligned species. Their habitat is invaded by us all the time with noisy motorboats. Think how we would feel if someone uses a drilling machine close to your ear. And then think how you will talk with someone in such a situation. You have to raise your voice over and above that sound to make yourself heard. That is what happens with the dolphins as well. They get really stressed by all the anthropogenic noise. These thoughts were flashing across my mind last month, when we were watching the dolphins in Sundarbans.
