Shark Tribe
This interesting documentary explores how a tribe of New Guinea natives (known as the Sharkcallers of Kantu) show no fear of sharks whatsoever - they head out into the ocean in small canoes and capture and hunt the sharks using their hands and small, handheld weapons. Where most people fear sharks, these guys have based pretty much their entire culture around them. They lure the sharks in without using any bait, instead using different noises to attract them. Along the way we get a look at their unique culture and how they've managed to survive over the years. From there, we actually witness the tribesmen out hunting while ecologists debate the morality of it.
