Garza said she hopes to show people tuning in to \"World's Biggest Tiger Shark?\" new information on the predators, including never-before-seen hunting tactics and uncommon filming locations.

\"Almost everything you see from tiger shark documentaries is from the same spot -- Tiger Beach, Bahamas. I'm excited to share the French Polynesian, Tahitian sharks because it highlights our shark sanctuary, one of the biggest in the world,\" she said. \"It's important to see how these sanctuaries support ecosystems with these big predators on top.\"

\"World's Biggest Tiger Shark?\" premieres July 19 at 8/7c on National Geographic. An encore presentation will follow on Aug. 11 at 9/8c on Nat Geo Wild.
