More Detail
Built like a torpedo with a mouthful of teeth, the Wolf Fish is an ambush predator that hits like a freight train and doesn't let go. It's an air-breather capable of surviving in low-oxygen water, and its raw, teeth-first aggression toward topwater lures has earned it a cult following among anglers looking for something with real bite.
