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.
