A BBC special called “Human Planet” featured the amazing ability of Sulbin, a Bajau diver from the Philippines. Sulbin is able to hold his breath for over 2 ½ minutes on the sea floor while searching for a fish to harpoon! Even more amazing is that at these depths (up to 65 feet!), Sulbin’s lung capacity is reduced by about a third!
You can see this incredible feat in the following YouTube video:
