Nothing' fishing is not a lure. It is really more of a tactic, or method of presentation. There are a lot of lures that lend themselves to the 'nothing' approach. The most versatile are soft plastics, but topwater lures and some crank plugs can also be used. In a nutshell, 'nothing' fishing is using a fish's lack of smarts against himself.
All predators have basically the same trait towards obtaining food.
Injured prey is even better. It's an easy catch. They do not have to expend energy to catch it. They absolutely cannot sit still and watch what might be prey slowly move past them. Whether hungry or not, they have to try and get it.
