The Riddle of the Hammerhead Sharks

Overview

Far out in the Pacific Ocean off Hawaii, Christina Karliczek Skoglund wants to film what are perhaps the most enigmatic sharks of all: hammerhead sharks. Together with marine biologist Florian Graner, she embarks on a risky dive to a depth of over 40 meters – at a remote, difficult-to-access dive site with strong currents. They want to document a behavior that has never been recorded there before. Will they succeed? And the great white shark also poses a mystery: off the coast of South Africa, these animals have completely disappeared from some regions. Do orcas play a crucial role in this?
