"The study reports that when hunted by large predators, such as sharks and snapper, small fish hide and move around less. When predator numbers are seriously reduced, their prey move greater distances, take more risks, and change feeding behaviours. These behavioural responses in prey species also drive significant changes in the balance of ecosystems."
