Bait balls are a form of protection for the preyfish. By forming up into a compact ball, the predator is presented with a large mass that prevents them from singling out anyone particular baitfish to attack. The ball is constantly moving, changing direction, presenting a indiscriminate mass to attack. What will usually happen wil be the predator will attack the ball to break it up, causing some preyfish to be segregated so that they can be attacked while the rest of the ball will swim away.
