Global analysis reveals how sharks travel the oceans to find food

A major international collaboration, including AORI researcher Dr. Alex Wyatt and authors from 20 other countries, could help global efforts to overturn recent declines in the world’s shark population by providing greater insight into the feeding habits of the world’s most misunderstood fish.
