Octopus arms have segmented nerve systems, controlling movement and sensory input. Each segment enables independent control.
Each arm can also react independently to stimuli without involving the central brain. (There’s a rather gruesome demonstration of the latter fact: “Amputated octopus arms,” Olson says ...
The large nerve cord that runs along each octopus arm is divided into segments, allowing for precise movement control and ...
The suckers are also packed with sensory receptors that allow the octopus to taste and smell things that they touch—like combining a hand with a tongue and a nose. The researchers believe the ...
Transparent walls enabled the octopus to see the food. Most of the octopuses were eventually successful at guiding their arm to the food – proving that the central brain, which processed the visual ...
Each octopus arm has a massive nervous system, with more neurons combined across the eight arms than in the animal's brain. These neurons are concentrated in a large axial nerve cord (ANC), which ...
As a result, each of the eight arms of an octopus has its own mini brain, while the ninth, central brain is located between the eyes and shaped like a doughnut around the esophagus. Read more ...
Indeed, a particular part of the octopus brain, the vertical lobe, is dedicated to such tasks. I’m stressing the common octopus here because it has been studied the most, by far. Octopus species ...
Octopus arms are the ultimate multitaskers, bending, twisting, and curling with an impressive range of motion that would make a yoga instructor envious.
In many animals, including humans, a centralized brain serves as the decision-making hub, or controller, for the rest of the body. In contrast, octopus "brains" are distributed along the eight ...
The cuttlefish has one of the largest brain-to-body size ratios of any invertebrate, perhaps even larger than that of the octopus. The cuttlefish brain can handle input from a variety of senses ...
