A dangerous tagging mission in South Australia reveals what sharks eat and why they gather at feeding sites. The team in the north pursues tiger, bull, and hammerhead sharks, and equips one with a 360-degree back camera.
Two teams of researchers investigate the migration patterns of the ocean's largest and deadliest sharks. They follow their underwater routes and show their hunting behaviours, and social hierarchies.
The northern team attach an activity tag to a bull shark, then dive more than 250 feet deep to put a satellite tracker on a great white.
Discover shark community hierarchies as the northern team studies how young blacktips learn social and survival skills. Plus, a look at Rainbow Beach with the southern team, who witness the sand tiger shark's most elusive behaviour: mating.
Travelling to the ends of Australia's shark highways to discover if Greenly Island is a truck stop for migrating great whites. Plus, a search for proof of a genetic connection between northern bull sharks and their cooler-climate cousins.
Following the southern team as they test new migration tech and tools that could reduce shark attacks in a popular snorkelling spot. Catch and tag bull sharks with the northern team, who want to help local swimmers steer clear of birthing mothers.
