One of the hallmarks of the collective movement of large schools of pelagic fish are waves of shimmering flashes that propagate across the school, usually following an attack by a predator. Such flashes arise when sunlight is reflected off the specul

The risk of predation presents a difficult challenge in environments that offer no physical shelter, such as the open waters of the world's seas. In the absence of hiding places, many marine fishes turn to two main anti-predator strategies: aggregati

The configuration is identical to the one generated figure 3 except that the detectability threshold is 0.01 instead of the threshold of 0.3 that we used in our analyses. The detectability patterns are qualitatively the same despite the large differe

As an example, we mark two possible observer directions. The single fish that is detected by the observer on the right is flashing brightly, while the many fish detected by the top-left observer are only slightly above the contrast sensitivity thresh

(a) Determining ray-fish intersections. Each ellipsoid fish is transformed to sphere of radius 1. The distance between this transformed fish to an equally transformed copy of the ray was calculated. A distance smaller than 1 implies an intersection.

Comparison of specular and diffusive aggregates, shaped as either a sphere or a cylinder. We compare contrast maps of the strongest-flash (right), and flux of flashes for an observer with high (10.0, left column), or lower (0.3, middle column) contra
