National Geographic Emerging Explorer, aquatic ecologist, and megafish-finder Zeb Hogan travels to lakes and rivers the world over to document and protect the planet’s largest freshwater fish. Tonight, the National Geographic Channel premieres a new episode of Hooked that follows Zeb into the Australian outback in search of one of the most critically endangered—and peculiar-looking—fish on Earth, the giant freshwater sawfish.
Need something to do while you’re waiting for the show to air? Check out the megafishes photo gallery, read National Geographic News’ nine-part series on the Megafishes project, scan Zeb’s picks for Top Ten Ugly and Endangered Fish, or try your hand at the Hooked: Reel ‘Em In game. (I did myself, but the fish kept getting away before I could land them. Can you do better?)
