Curious Case of the Octopus Brain

Octopuses, belonging to the class Cephalopoda, have one of the most peculiar anatomical setups in the animal kingdom.

While having three hearts itself sounds surreal, what's even more intriguing is their brain structure.

Two-thirds of an octopus's neurons reside not in its central brain but in its arms! Yes, you heard it right.

The octopus's eight arms have a mind of their own, capable of operating semi-independently.

This decentralised nervous system allows an octopus to multitask, that is, its arms can perform different tasks simultaneously, while the central brain is free to focus on other high-level cognitive functions.

Fascinatingly, it also means that even when an arm is severed, it can still react to stimuli and attempt to behave naturally.

Such potent autonomous function and flexibility are part of what makes octopuses so hardy and proficient at adapting to varied environments..
