The Amazon river dolphin is the largest species of river dolphin, with adult males reaching 185 kilograms (408 lb) in weight, and 2.5 metres (8.2 ft) in length.

Like other toothed whales, they have a melon, an organ that is used for bio sonar.
The Amazon river dolphin are commonly seen singly or in twos, but may also occur in pods that rarely contain more than eight individuals.
