Goliath Tigerfish
As the name suggests, the goliath tigerfish is a sight to see, and not just because of its size. This beast of a fish can be found in the Congo River Basin, and it can grow to be massive. Some have been known to weigh up to 110 pounds, and others have been known to attack humans. It has rows of super sharp teeth with razor-sharp edges.
As if its size and teeth were not intimidating enough, the goliath tigerfish can easily capture prey with its mouth. The African-based fish usually hunt in groups, and they can jump and catch birds in mid-air.
