At the western edge of Australia’s Outback, Wild Chronicles joins National Geographic’s Crittercam® to explore the warm, summer waters of Shark Bay, home to thousands of tiger sharks. Lurking in the coral reef’s vast seagrass beds, the opportunistic hunter eats anything and everything. But, as Crittercam® discovers, tiger sharks also keep this fragile ecosystem in balance.

  1. Tiger sharks are just one part of the ecosystem of Shark Bay. What else is part of the ecosystem?

    • Answer

      Coral reefs, seagrass, fish, dolphins, turtles, and dugongs are all native to Shark Bay.

  2. How many sharks has Mike, the biologist, tagged in Shark Bay?

    • Answer

      Mike has tagged more than 250 sharks.

  3. Besides a camera, what other equipment does Crittercam carry?

    • Answer

      Crittercam instruments measure the depth and temperature of the water in Shark Bay.

  4. What is "Gut Cam"?

    • Answer

      Gut cam is a device for looking into a shark's stomach to see what it has eaten.

  5. How do tiger sharks help keep the Shark Bay ecosystem in balance?

    • Answer

      Dugongs and turtles eat tons of seagrass, the primary producer for the Shark Bay ecosystem. Tiger sharks help control these populations, allowing seagrass to flourish.
