What happened

Sharks thrive in hotspots of prey, underlining need for holistic approach to conservation Stephanie Baum Scientific Editor Robert Egan Associate Editor Sharks need healthy habitats, and some have a strong preference for locations jam-packed with food,…

Why it matters

A recent study of Caribbean reef sharks in the Bahamas, where shark fishing has been banned for years, shows that the sharks don't seem to like places where prey is hard to find.

Common ground

Instead, they prefer to live where prey is most abundant.
