Field Notes

Description:

The Amazon River Dolphin is exclusively a freshwater species occupying rivers and lakes in Amazonia. They are frequently seen in Coca from the bridge over the Napo River. Sightings consist of single individuals, pairs or a few individuals or so. They swim slowly but are extremely maneuverable. A common mode of surfacing is ascending horizontally and showing only the melon (top of the head) and/or the dorsal crest. While deep diving, it is often possible to view more of this species including the snout. On rare occasions, they jump right out of the water. These dolphins make their presence known even without seeing them by the loud blowing sound produced when they exhale. They are very curious and playful.

The Amazon River Dolphin averages about 2 meters in length and come in all shades of color from pink, dull gray-pink, rosy colored pink, bright pink or pinkish blue. The darker the water, the pinker the dolphin will be and the sun’s rays cause the dolphins to loose their pink pigmentation. They also become pinker when excited. No discernible dorsal fin.

Habitat:

This large species is seen in Coca, Pañacocha, Yasuni National Park, the Aguarico River, Cuyabeno and the Napo River into Peru and the Amazon River.

Notes:

We were lucky enough to spot a mother and calf.
