Octopuses tend to keep secrets, but we've just learnt how they achieve their extraordinary dexterity. The fine control these almost-alien animals have over each of their eight arms is at least ...

The large nerve cord running down each octopus arm is separated into segments, giving it precise control over movements and creating a spatial map of its suckers. Octopus arms move with incredible ...

Olson explains that “there are many gross similarities [between the ANC and vertebrates’ spinal cords]—there is a cell body region, a neuropil region, and long tracts to connect the arms and brains in ...

Octopuses are not much like humans — they are invertebrates with eight arms, and more closely related to clams and snails. Still, they have evolved complex nervous systems with as many neurons as in ...

Octopuses have more than 2,000 suckers on eight arms, and each one is controlled individually, making these critters incredibly dextrous. So when a team of researchers wondered how to design a glove ...

For scientist Dominic Sivitilli, a Ph.D. candidate in astrobiology and psychology at the University of Washington, the answer is under the sea. “The octopuses’ long, separate evolution toward ...

A new study on the intramuscular nerve cords of octopuses reveals that they are connected in a unique and unexpected geometric structure. Octopuses are not much like humans -- they are invertebrates ...
