Terry Manuel
This 1974 incident took place off the coast of South Australia. Terry Manuel finished an afternoon dive when a great white shark hit him at a speed of 25 MPH. Talbot, his boatmate, was able to hold onto his arm and pull him back into the boat. He bled to death before rescuers could come to his aid, however.
David Lilienfeld
David Lilienfeld was a young bodybuilder who had been spending a day at the beach with his family. They had been hanging out at Kogel Bay in Cape Town, South Africa when the unbelievable happened. He had just entered the water when a shark attacked him. People watched in shock as the animal ripped into the right leg of the 20-year-old athlete. He was pronounced while he was inside an ambulance.
