Gangetic Dolphin: On the verge of extinction
Dolphin is basically a mammal found in the oceans, but some of its species are also found in freshwater. Just a few years ago, only 4 out of 88 freshwater dolphin species in the world were found to be alive, but only 3 remained by 2006. The dolphin named Baigi was found in freshwater of the Yangtze River of China, which is now gone extinct. Now except for the Ganga, only two dolphin species are found only in the Indus and Amazon rivers, which are known as Bhulan and Bota.
