The Amazon pink river dolphin is a unique specie that lives only in freshwater. It is mostly found in the Orinoco and Amazon river basins in countries: Guyana, Peru, Brazil, Colombia, Ecuador, Bolivia, Venezuela, etc.
Currently, this specie is at high risk of extinction as there are only 2000 pink dolphins left.
The major reason behind their extinction is the contamination of rivers and lakes and the construction of dams.
However, the number of pink dolphins has increased during the COVID-19 pandemic era.
