The Mystery of the Octopus Brain

Octopuses are considered one of the most intelligent creatures in the ocean, but their brains function in a fascinatingly different way than ours do.

In an octopus's nervous system, about two-thirds of its neurons are located not in its brain, but rather in its arms.

This decentralization of the nervous system allows the arms to work semi-independently, performing complex tasks even when detached from the body.

Furthermore, octopuses have the incredible ability to regenerate lost limbs, resulting in full functional restoration including these 'arm brains.' While an octopus has both short- and long-term memory, how these memories are stored and accessed in this distributed nervous system remains a mystery to scientists.

This fact not only highlights the alien-like adaptability of the octopus, but also points to how much we still have to learn about the diverse forms of intelligence on our own planet..
