Sharks, unlike your average fish, play a different role in the marine ecosystem. While being at the top of the food chain at most times; sharks help to keep other populations of fish with the appropriate size, and by doing that, they also keep other fish and organisms healthy. Over the years, sharks developed an inter-dependency with their ecosystem. They many times eat the fish that are already more debilitated. By doing that, the amount of healthy fish population subdues the debilitated, which means that mainly the healthiest fish will reproduce, originating a generation of healthier and stronger fish. Another impactful role is controlling the spreading of diseases and impeding outbreaks, which also makes a healthier
