When they call it a river monster, they aren't kidding!
In River Monsters, biologist Jeremy Wade scours murky waters across the globe for the world's largest, strangest and most dangerous fish.
Like a larger-than-life catfish that makes really wierd sounds. This beast is called and Arapiemah. The moster fish has plenty of fight, but even a river monster has to surrender in the end.
River Monsters premieres sunday night at 10 on Animal Planet
Watch the video of Wade reeling in the monster fish.
