TED-Ed: Why the octopus brain is so extraordinary - Claudio L. Guerra

Octopuses share some cognitive abilities with humans, such as solving puzzles and using tools, despite having a vastly different biological structure. Their nervous system is decentralized, with neurons distributed throughout their body, particularly in their tentacles, allowing for independent arm movement. This unique setup enables octopuses to perform complex tasks and adapt to new situations. Their intelligence has inspired research in robotics and offers insights into the evolution of intelligence and consciousness.

What unique abilities do octopuses share with some other animals?

• Singing

• Flying

• Solving puzzles

• Building nests

How is the nervous system of octopuses different from that of vertebrates?

• It is centralized in the brain

• It is located only in the tentacles

• It is spread out in a network of ganglia

• It has fewer neurons than a dog

What allows octopuses to bend their limbs in any direction?

• Their lightweight body

• Their rigid skeleton

• Their jointed limbs

• Their lack of bones

How do octopuses respond when they see food?

• They freeze in place

• They initiate a behavioral response

• They change color

• They activate a specific body part

What has octopus intelligence inspired in the field of robotics?

• Invention of underwater vehicles

• Development of flying drones

• Creation of soft, flexible robots

• Design of humanoid robots
