Also known as Freshwater Shark or Helicopter Catfish, Wallago have the face of a bullhead and an eel-like body. Their mouth is filled with sharp teeth that point backwards so anything entering the mouth will never leave it. Bites strongly if handled, with its huge mouth, formidable jaws, and band of conical teeth. Threatened due to over harvesting. In Malaysia they are bred commercially in fish farms for food.
