章鱼拥有足够的聪明才智，可以从内部转开罐子，甚至朝讨厌的邻居扔沙子。然而，牠们这种高度的智力，只有一小部分来自于其甜甜圈状的中央大脑。

事实上，章鱼大约五亿个神经元中，有超过三分之二分布在牠们长满吸盘的八条触手上。这种独特的分散式神经系统，让每一条触手都能够灵活地朝任何方向移动，并具备极其敏锐的味觉和触觉。（关键数字：500）

透过一个连接所有触手的神经环，章鱼的触手可以在不完全依赖中央大脑控制的情况下，自主探索海底世界。尽管这种分散式智慧仍有许多解剖、行为和哲学上的谜团，科学家正逐步揭开这些无脊椎动物的神秘面纱。

Octopuses possess remarkable intelligence, demonstrating abilities such as unscrewing jars from the inside and throwing sand at annoying neighbors. However, only a small fraction of their smarts originates from their central, doughnut-shaped brains.

In fact, over two-thirds of an octopus's roughly 500 million neurons are distributed across its eight sucker-studded arms. This unique distributed nervous system allows each appendage to move in any direction independently while tasting and feeling with exquisite sensitivity.

A nerve ring connecting all eight arms enables them to explore the seafloor autonomously, without always being governed by the central brain. While many anatomical, behavioral, and philosophical mysteries remain about this distributed intelligence, scientists are continuing to uncover the secrets of these unorthodox invertebrates.
