There are many different kinds of dolphins, some very big and some very small. Some dolphins live in the oceans and others in rivers. Most scientists agree that there are a least 32 species of marine dolphins and 4 species of dolphins that live only in freshwater rivers but nobody knows for certain just how many species there are.
Here we mention 5 of the most interesting species:
1- The Ganges river dolphin, also known as the susu, lives in India.
