Pink Dolphin
Human interest in the pink dolphin arouses from the very cute pink color! These dolphins have the ardent feature of surviving in rivers, which means that they do not live in seawater. Found primarily in the South American region of the Amazon river, these dolphins are considered to be quite intelligent.
 

It will be surprising to note that these dolphins resemble the human tendency to get pink when blushing! They are prominent due to their accurate sight vision and playful nature. Interestingly enough they are considered to be loners, in the sense that they do not form very large pods when hunting.
