700 requins dans la nuit

Imagine diving into the ocean only to discover that you are surrounded by one of the largest shark frenzies on the planet. Well, that is exactly what these researchers did in the name of science. In Polynesia, the largest school of sharks — about 700 — patrols the waters en masse. Follow an international team of scientists as they study these magnificent creatures at night, when they are most aggressive, to discover their mysterious hunting strategies and social behaviours. The result: incredible new behaviours never seen before, or caught on camera.
