In thousands of years, piranhas in the rainforest might change, or adapt, due to climate change. An adaptation that may occur with piranhas is that they may have spikes on their bodies. In this scenario, climate change will cause ocean levels and temperatures to rise. The change in the ocean will start forcing bull sharks from the ocean to move to the Amazon’s rivers. With more competition for food in the rivers, bull sharks will start eating the piranhas in the Amazon. This will unbalance the relationship of piranhas versus predators, and the piranhas will need to adapt. A genetic mutation in some of the piranhas will result in them having spikes on the top of their bodies. This mutation will make it harder for predators to eat the piranhas, allowing these piranhas to survive. Over many generations, the spikes become a predominant trait amongst piranhas in the Amazon’s rivers.
