Something fishy is going on at Animal Planet. Something killer fishy.

In the second season of 'River Monsters' premieres Sun., April 25 at 10PM ET, host Jeremy Wade continues his search for the world's largest, weirdest and most dangerous fish.

The extreme angler and biologist travels across the globe, from Texas to the Congo, and wrestles with monsters like the ferocious Goliath tigerfish, the venemous freshwater stingray and the predatory giant snakehead.

Wade stopped by AOL TV's office to chat about his killer fish adventures and where he'd like to go next.
