In 2013, fishers off Southern California reeled in an enormous, 11-foot-long mako shark. At over 1,300 pounds , the animal — dubbed"The Beast" — was one of the heaviest mako sharks ever recorded.
In the new Shark Week show"Makozilla," shark biologist and wildlife presenter Craig O'Connell went looking for supersized makos to find out if only one shark had grown to a mammoth size, or if the individuals in the North Pacific population are now much larger than they once were. "Are there more absolutely massive makos out there, and how are they related?" O'Connell told Live Science.

The results showed that the sharks were related — but it was unclear how closely related they were, such or whether they were direct descendants.
