The Amazon River Dolphin changes from gray to pink when they get older. The Amazon River Dolphin eats fish, shrimp and crabs. They can also eat piranhas and turtles. They are carnivores. In the future, because of pollution, the fish in the rivers died. Green algae has taken over the river and the dolphin has to adapt to eating algae to survive. The dolphin’s skin changed and became green because of the algae it eats. The rising water temperature created more algae and turned the water green and the dolphin turned green so the dolphin could camouflage in the river. The dolphins needed to hide from humans because humans are the dolphin’s main predator. The dolphin adapted and became a herbivore.
