Why We Need Sharks: Amazing Sharks Online Course Ep 3

As APEX predators, sharks sit at the top of the food chain and help control the numbers of animals below them in the food chain - they maintain the balance of life.
By controlling numbers of large and mid-sized predators, sharks allow smaller fish to thrive, ensuring healthy ecosystems with a diverse range of species and competitors. Apex predators like sharks are known as keystone species. This means that they are crucially important. Take sharks out of the food chain and the whole structure could collapse.
