Thee Amazon River Dolphin

In the future many animals will change and my animal (The Amazon River Dolphin) will also change, and here are some changes I imagine would happen. 360 degrees view to warn if humans are near, A larger body to intimidate prey and predators, larger and flatter and sharper dorsal fin to swim faster and to avoid humans and to glide through the water. Mostly gray on top to protect the harsh sun in the future, longer and sharper teeth to eat better. Another adaptation would be a net at the back fin to capture garbage in the rivers in case they move to the ocean garbage in the ocean. They would have tougher skin to protect their skin from humans. Another major adaptation would be retractable legs in case there aren't any rivers and they have to move to the ocean or live on land for short periods of time.
