Watch The Unreasoning Shark

As film maker John Stoneman and marine biologist Alan Emery confirm, people rarely encountered sharks in the past. When they did, injuries and death were frequent effects. Divers experience sharks up close and personal thanks to dive operators such as the Nassau Scuba Centre in the Bahamas. Divers wearing chain mail suits, interact with sharks and offer bloody bait to the swirling frenzies.

The Unreasoning Shark is a 2017 documentary with a runtime of 23 hours.
