Proto-cooperation: group hunting sailfish improve hunting success by alternating attacks on grouping prey.
We present evidence of a novel form of group hunting. Individual sailfish (Istiophorus platypterus) alternate attacks with other group members on their schooling prey (Sardinella aurita). While only 24% of attacks result in prey capture, multiple prey are injured in 95% of attacks, resulting in an increase of injured fish in the school with the number of attacks. How quickly prey are captured i...

متن کاملThe Evolution of Lateralization in Group Hunting Sailfish
Lateralization is widespread throughout the animal kingdom [1-7] and can increase task efficiency via shortening reaction times and saving on neural tissue [8-16]. However, lateralization might be costly because it increases predictability [17-21]. In predator-prey interactions, for example, predators might increase capture success because of specialization in a lateralized attack, but at the c...
متن کاملGroup Size Effect on the Success of Wolves Hunting
— Social foraging shows unexpected features such as the existence of a group size threshold to accomplish a successful hunt. Above this threshold, additional individuals do not increase the probability of capturing the prey. Recent direct observations of wolves (Canis lupus) in Yellowstone Park show that the group size threshold when hunting its most formidable prey, bison (Bison bison), is nea...
متن کاملA novel meta-heuristic optimization algorithm inspired by group hunting of animals: Hunting search
A novel optimization algorithm is presented, inspired by group hunting of animals such as lions, wolves, and dolphins. Although these hunters have differences in theway of hunting, they are common in that all of them look for a prey in a group. The hunters encircle the prey and gradually tighten the ring of siege until they catch the prey. In addition, eachmember of the group corrects its posit...
