Fast prey: Even non-attacking predatory fish benefit from group hunting at high speed

Why do animals actually hunt in groups when they have to share the prey afterwards? Researchers from the Cluster of Excellence Science of Intelligence (SCIoI), in which Humboldt-Universität zu Berlin (HU Berlin) and the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) are involved, have shown in a field study in the ocean off Mexico that the faster the prey school moves, the higher the capture rate of the striped marlin.
