Pink Dolphins, when you see, can melt your heart away. These pink-colored dolphins are also known as the Amazon pink river dolphin. Pink dolphins are so hard to train that they are rarely held in captivity, which is good.
The Amazon pink river dolphin has the largest bodies and brains of any freshwater dolphin. A full dolphin can grow up to 9 feet, weigh up to 400 pounds, and live up to 30 years old.
