Abstract

How an octopus performs complex movements of its eight sucker-studded arms without entanglement has been a mystery. A new study has found that self-recognition of the octopus's skin by its suckers inhibits reflexive grasping of its own arms, simplifying the mechanisms needed to generate intricate arm behavior.

摘要

章鱼如何在不发生缠绕的情况下，运用其八条布满吸盘的手臂做出复杂动作，一直是个谜。一项新研究发现，章鱼的吸盘对自身皮肤的自我识别会抑制对自身手臂的反射性抓握，从而简化了产生复杂手臂行为所需的机制。
