Pink Dolphin being feeded
The pink dolphins are not equal to the dolphins that are in the sea, but have special adaptations to their habitat. In fact, river dolphins are distantly related to sea dolphins because they belong to different families. The oceanic dolphins belong to the family (Delphinidae), while river dolphins belong to the family (Platanistoidea).
Among the species of river dolphins, pink dolphins of the Amazon are considered the most intelligent, with a brain capacity 40% greater than that of humans.

These dolphins live in the Amazon, but can also be found in
 the basins of the Orinoco and
 the upper Madeira River. Although
they are
mostly pink can be found in other
colors such

The Amazonian dolphins have small eyes, a long snout and dorsal fin very underdeveloped. These dolphins are very well adapted to living in the varzeas (flooded forests). Its distribution covers the river systems of the Amazon and Orinoco rivers.
The Amazonian dolphin is categorized as vulnerable. Their greatest enemies are deforestation and human activities that contribute to disrupt their livelihood.
