Each minute of video took hours to analyze, Buresch said. All in all, the researchers cataloged 3,907 arm actions that required 6,871 arm deformations. The inventory of the animals’ arm movement could help researchers better understand the neural connections that allow octopuses to coordinate their arms to work in different combinations and to receive feedback from the environment. A mating …

WASHINGTON (AP) — Humans may be right-handed or left-handed. It turns out octopuses don’t have a dominant arm, but they do tend to perform some tasks more often with their front arms, new research shows. Scientists studied a series of short videos of wild octopuses crawling, swimming, standing, fetching, and groping — among other common activities — to analyze how …

While some humans find they have two left feet on the dancefloor, octopuses manage to coordinate eight highly flexible arms across a host of behaviours, from foraging to den-building, or moving around the seafloor. Now researchers say they have completed the most comprehensive study of its kind, not only identifying the actions and small motions involved in different types of …

Octopuses can be fooled into thinking a fake arm is actually their own. When scientists in Japan pinched an artificial appendage during experiments, octopuses recoiled in defense – swimming away, suddenly changing their color, or retracting their arms, as if they’d really been hurt. The reaction is not proof that cephalopods are dim-witted or easily tricked – quite the contrary. …

Imagine reaching for a cup and feeling as though your hand is moving, only to discover it’s not your hand, but a rubber replica being touched in sync with your real, hidden hand. You still react, convinced the fake rubber hand is yours. Humans fall for this trick every time, and now we now know that octopuses fall for it, …
