Abstract
One of the main reasons that fish form schools is that it serves to <br /><br />reduce the risk of being eaten. Single predators are most successful at capturing <br /><br />individuals not in schools. For every successful anti-predator strategy by a prey <br /><br />species there is usually a concomitant more successful strategy by the predators. <br /><br />I report here on the behavior of three species of predatory fish and two species <br /><br />of predatory birds toward a school of jacks, Selar crumenophthalmus which dem- <br /><br />onstrate that these predators use a variety of methods to obtain fish from a school.
