The weeklong SharkFest heads back Down Under to Australia for back-to-back explorations of shark activity. In Reef Rivals, scientists study an island on the Great Barrier Reef where an unusual variety of ocean predators converge to hunt for turtles, birds, and other sources of survival. Followed by Great White Gauntlet (10/9c), which tracks shark experts on remote Greenly Island as they tag a great white shark with a camera to reveal their hunting practices among a colony of seals and sea lions.
