Amazon River Dolphin

So they can adapt to a changing climate and warmer temperatures, I have given the Amazon River Dolphin more back muscles and a more aerodynamic/hydrodynamic body shape to move faster and for longer so they can find cooler areas or they can repeatedly jump out of the water to cool off. These adaptations also improve the Amazon River Dolphin's effectiveness for hunting their prey, and escaping from predators, further increasing their survival rates.
