Pink Dolphin (Inia geoffrensis): Live in the Amazon & Orinoco River
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 as skin clear, pink or brownish gray.
The Amazonian dolphin is categorized as vulnerable. Their greatest enemies are deforestation and human activities that contribute to disrupt their livelihood.
