在日本白滨浅水区对食饵-捕食者相互作用进行了野外观察，重点研究了空刺雀鲷的围攻行为。在雀鲷的繁殖群体中，观察到了对6个跟踪者的间接群体围攻和仅由筑巢雄性对跟踪者进行身体接触的直接围攻。直接向跟踪者（海鳗）的围攻被认为涉及到一种保护卵的因素。群体围攻通常是由捕食者的大而快的攻击动作释放的。捕食者被围后的攻击间隔时间比未被围时长得多，但是否引发围杀对下一次攻击的成功率没有显著差异。因此，可以得出结论，围攻有效地降低了未来的捕食风险的每个暴徒。
Field observations on prey-predator interactions, focusing on mobbing behavior byPomacentrus coelestis, were made in the shallow water of Shirahama, Japan. Within the breeding colony of the damselfish, indirect group mobbing toward 6 ambushers and direct mobbing with physical contact only by nesting males toward a stalker were observed. The direct mobbing toward the stalker (moray eel) is suggested to have involved an element of egg-guarding. Group mobbing was usually released by large and quick attacking motion of the predator. Attack intervals of a predator were much longer after it was mobbed than when it was not mobbed, but there was no significant difference in success ratio of the next attack whether mobbing was elicited or not. Consequently, it is concluded that mobbing effectively reduced future predation risk of each mobber.
