  abstract = {{T}he costs and benefits of group living often depend on the spatial position of individuals within groups and the ability of individuals to occupy preferred positions. {F}or example, models of predation events for moving prey groups predict higher mortality risk for individuals at the periphery and front of groups. {W}e investigated these predictions in sardine ({S}ardinella aurita) schools under attack from group hunting sailfish ({I}stiophorus platypterus) in the open ocean. {S}ailfish approached sardine schools about equally often from the front and rear, but prior to attack there was a chasing period in which sardines attempted to swim away from the predator. {C}onsequently, all sailfish attacks were directed at the rear and peripheral positions of the school, resulting in higher predation risk for individuals at these positions. {D}uring attacks, sailfish slash at sardines with their bill causing prey injury including scale removal and tissue damage. {S}ardines injured in previous attacks were more often found in the rear half of the school than in the front half. {M}oreover, injured fish had lower tail-beat frequencies and lagged behind uninjured fish. {I}njuries inflicted by sailfish bills may, therefore, hinder prey swimming speed and drive spatial sorting in prey schools through passive self-assortment. {W}e found only partial support for the theoretical predictions from current predator-prey models, highlighting the importance of incorporating more realistic predator-prey dynamics into these models. {T}his article is part of the themed issue '{P}hysiological determinants of social behaviour in animals'.},
