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 ...

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 ...

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 possess a unique three-heart system that allows them to survive temporary cardiac pauses, a feat impossible for most animals. This, combined with their efficient haemocyanin oxygen carrier ...

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 ...
