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.
To date, Zeb’s work on the ambitious Megafishes project has helped lead to protection for the giant Mekong catfish and creation of a preserve for the giant stingray and the giant barb.
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?)
