章魚擁有足夠的聰明才智，可以從內部轉開罐子，甚至朝討厭的鄰居扔沙子。然而，牠們這種高度的智力，只有一小部分來自於其甜甜圈狀的中央大腦。

事實上，章魚大約五億個神經元中，有超過三分之二分佈在牠們長滿吸盤的八條觸手上。這種獨特的分散式神經系統，讓每一條觸手都能夠靈活地朝任何方向移動，並具備極其敏銳的味覺和觸覺。（關鍵數字：500）

透過一個連接所有觸手的神經環，章魚的觸手可以在不完全依賴中央大腦控制的情況下，自主探索海底世界。儘管這種分散式智慧仍有許多解剖、行為和哲學上的謎團，科學家正逐步揭開這些無脊椎動物的神祕面紗。

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.
