Indus dolphins are an endangered species in Pakistan, whose numbers are still dwindling thanks to pollution, the increase of fishing, and irrigation. In 2006, estimates put the number  of these freshwater dolphins at 1200. What is unique about this creature is that the dolphins are blind – they use sonar to find their food.

The Pakistani activists who are trying to save the dolphin are doing so through education. Previously, farmers would shoot dolphins who got stuck in their irrigation ditches, but thanks to the work of Nazir Mirani and others, the dolphins are being rescued.
