700 Sharks

In a ground-breaking experiment in Polynesia, five of the most experienced underwater scientists in the world study the largest school of sharks every recorded. The researchers spent three years preparing to immerse themselves in a frenzy of 700 sharks at night, when they are at their most aggressive. They put their lives on the line to study the mysterious hunting strategies and social behaviour of these creatures. The result is a fascinating film in which the sharks demonstrate behaviour never before seen, let alone captured on camera. 

Dr Damien Sonny, one of the researchers in the film, specialises in acoustic technologies that help identify the behaviour of fish. He is currently conducting research in Europe’s major rivers, focusing specifically on eel migration in the Meuse. How can we prevent eels from going extinct?
