Fish Warrior: Colossal Catfish

Jakub Vâgner is all smiles with his massive 8-foot-8-inch Piraiba with an estimated weight of around 475 pounds.
Vágner ventures into the world's largest rain forest to go head-to-head with the giant piraiba catfish. These megafish can stretch nearly 12 feet long and weigh a scale-busting 440 pounds. Though mainly preying on other fish, they have been known to eat birds and even monkeys. Local legend even tells of these powerful predators dragging fishermen to the river's bottom! Vágner endures torrential rain and sleep deprivation to catch this mega catfish of the Amazon.
