The Social Network

T1, E4: Even the most solitary sharks need others to survive. But how they hunt, protect each other and form social hierarchies is still mostly unknown to science. Great white sharks do not school or socialize the way other species, like sand tiger or grey reef sharks, do. Professor Charlie Huveneers and Dr. Lauren Meyer head to the southern Neptune Islands with new tagging technology to see if they can unlock a different story about these rogue sharks. Dr. Johan Gustafson, Dr. Bonnie Holmes and Colin Thrupp head to Orpheus Island in Queensland, a nursery ground for baby blacktip reef sharks, to uncover how the young learn social and survival skills.
