【石斑圍捕獵物 Groupers】

石斑魚會和其他的魚合作覓食獵物，像是裸胸鯙。由於他們有各自覓食招數，石斑魚在開闊水域以瞬間爆發速度覓食見長，裸胸鯙可以鑽進獵物藏身的岩孔縫隙。石斑魚和裸胸鯙覓食招數互補，因此同步合作可以收到絕佳效果。
他們會抖動頭部邀請夥伴加入狩獵，然後抖動身體送出訊號給合作夥伴，再以頭部指向獵物所在的洞穴並抖動頭部訊號。影片呈現的是青星九刺鮨合作圍捕獵物行為，其中一尾探查和鎖定獵物位置，另一尾則在周遭游動阻止獵物脫逃。

Groupers hunt collaboratively with other fish species, in particular the giant moray eel. Partner species benefit from hunting together because of their naturally complementary hunting tactics. The grouper possesses burst speed to capture prey in open water. Morays may access prey hiding in reef cracks and crevices because of their slender body. When two predators with complementary hunting techniques hunt simultaneously, they may increase their hunting success rate.
The invitation to hunt is initiated by head-shaking. Then, grouper poses shimmy signal, and orientates itself vertically and head-down while conducting distinct headshakes appearing to indicate an object. The video has showed that Cephalopholis miniata hunt collaboratively. One fish detected and located their prey hiding in reef cracks and crevices. The other swam around to stop prey from escaping.
