A documentary that "resurrects" the largest shark to ever swim in our oceans: the megalodon. Measuring up to 52 feet in length and weighing approximately 100,000 pounds, these prehistoric predators were the size of a humpback whale. However, unlike the placid humpback, the megalodon had 250 six inch long teeth, set in jaws six feet wide and eight feet tall, enabling it to exert a stronger bite force than any other creature in our planet's history.
