Practice question

Pack coordination can increase group-hunting efficiency by assigning complementary roles, synchronizing attacks, and reducing prey escape routes. Individuals may encircle prey, alternate pursuit, drive it toward ambushers, or coordinate the timing and direction of a final attack. These behaviors can raise capture probability, reduce duplicated effort, and permit capture of prey too large or dangerous for a solitary hunter. The net advantage depends on whether increased intake exceeds the costs of communication, competition, injury, and sharing the carcass; larger groups are not always more profitable per individual. Sleep cycles, solitary movement, and seasonal migration can affect predator ecology but do not constitute the within-hunt cooperation needed for coordinated capture. Communication through calls, posture, scent, or movement can maintain spatial roles and update partners as prey changes direction. Selection can favor such coordination through direct individual benefits, kin selection, or repeated cooperation. The mechanism is joint action that changes capture success or energetic cost, not mere simultaneous presence of several predators.
