Fear of sharks helps preserve balance in the world’s oceans

Fear of sharks helps preserve balance in the world’s oceans

A prey’s fear of a shark is critical to protecting ocean biodiversity, according to FIU researchers. Without this fear, a cascading effect within the ecosystem could destabilize the world’s oceans. Seagrass beds provide habitats for other fish and marine life — many of which people rely on. When predators, such as tiger sharks, rove in areas near seagrasses, herbivores...
