Most dolphins
live in the ocean, but there are some species which live in rivers.
While the most known species like the bottlenose and the spinner dolphin live in the ocean, some other live in
rivers like the Amazon river, the Ganges river, the Yangtze river, the La Plata river and the Indus river.
The better known of all them is the Pink dolphin, also known as "Boto" who lives in the Amazon river.
