A groundbreaking test developed by an FIU scientist can detect small, elusive hammerheads without anyone ever setting eyes on them — a critical new tool for species fighting for survival.

This first-of-its-kind test can detect traces of the sharks without ever catching or disturbing them. Like faint biological echoes lingering in the current, the test reveals where the sharks have been by identifying fragments of genetic material left behind in the water. In a recent study published in Frontiers in Marine Science , FIU marine biologist Diego Cardeñosa, who is affiliated with FIU’s Institute of Environment and the Global Forensic and Justice Center, demonstrates the test’s effectiveness, showing how it can help scientists locate and prot
