聪明绝顶的章鱼，竟会用暴力“奴役”其他鱼类？研究揭秘（讲解版）| E0930

▍原文

A new study shows that some species of octopus maraud around the seafloor in hunting groups with fish.

The researchers even witnessed the cephalopod species punching companion fish, apparently to keep them on task and contributing to the collective effort.

Octopuses have often been thought to prowl solo using camouflage. But the study suggests that some octopuses have surprisingly rich social lives—a finding that opens a new window into the marvels of undersea life.
