Juvenile critically endangered great hammerhead sharks (Sphyrna mokarran) flock to the waters of Biscayne Bay in southern Florida. Deploying this non-lethal method provides insights into recent and long-term feeding behaviors, and shows how their reliance on Biscayne Bay alters over time. The findings indicate that the sharks are in the bay year-round during their first two years of life, the young sharks rely on the shallow inshore habitats of Biscayne Bay and the prey they can access there.

According to the team, this indicates that the nearshore habitats are important throughout the great hammerhead’s entire life cycle.
