There are 2 new documentaries being shown in NatGeo and Discovery Channel about gigantic river fish that inhabit the rivers of the world. When you say large fish this is normally associated with Saltwater monsters like Marlin, Tuna and Shark. These documentaries claim that in large rivers lurk monster size fish that are capable man-eaters. Dr Jeremy Wade who hosts River Monsters, investigates cases worldwide of people being eaten by monster river fish. From the Alligator Gar in Texas, the Goonch in India, Mekong Giant Catfish and even Bull Sharks upriver, it is amazing to see fish this size inhabiting local rivers. Dr. Zeb Hogan of National Geographic goes around the world to survey and study these little known river giants."Many of the places I hope to explore have been virtually untouched by scientific study," Hogan notes. "It's a real chance to make discoveries about local biodiversity, compare the ecology of different river systems, provide new observations on animal behavior, and perhaps even discover new species."The world's biggest freshwater fish, many of which weigh more than 200 pounds (90 kilograms), face the biggest threats. That's why Hogan is undertaking a global survey of giant freshwater fish.
