Shark expert Alison Towner teams up with Shark Week legend Dickie Chivell to decode how killer whales take down great whites with ease. To get answers, the team travels to New Zealand and goes to the extreme, sending Dickie underwater posed as an orca to see how the great whites react.

In a Shark Week first, male and female great white sharks compete in a series of challenges to determine which sex is the superior predator in the waters off the coast of New Zealand.

Using data gathered in new experiments, Tristan Guttridge, Rosie Moore and Dr. Sora Kim construct a CGI fight to the death between two of the biggest and baddest apex predators in the water – the Great White Shark and Nile Crocodile.
