The body shape of the Amazon River Dolphin is very unique and that makes it easy to tell them apart from other species. They have a body that is long and filled out. They have fins that are shaped like paddles with a ridge on their back instead of a dorsal fin. They also have a bulging forehead which is called the melon. The eyes are small and they have chubby looking cheeks. The beak is very long and they can have as many as 140 teeth.
The color of this dolphin ranges from a bluish gray color to white. They can also be pink which is very interesting indeed. They have flexible necks because not all of the vertebrae in their necks are fused. This gives them the ability to move their head in various directions. They are the largest of all the river dolphins. The males can be just over 8 feet with the females around 7 feet long. The males can weigh up to 400 pounds with the females around 330 pounds.
What is very interesting is that in spite of such a heavy body, they are able to move with ease and not use a great deal of energy to do so. They have very broad flukes that are triangular shaped. They don’t swim fast but they are efficient in their movements. They have lots of trees and other elements in their habitat to maneuver around and they have no trouble doing so.
