Amazon palus delphina

Amazon River Dolphin in the Future I believe that in the future the Amazon river dolphin will change in multiple ways. These are how it could change if a rainforest were to evolve into a marsh. The pigment of their pink skin would be darker to match their new environment with the extremely murky waters. This breed of dolphin is very large as well, but it would probably be a little smaller later on so it could easily hide under the surface of the shallow water.
