Octopus arms are one of the most flexible structures known in all of the biological world. Their agility is so extraordinary that robotics researchers want to learn the secrets behind their movements, ...

Researchers studied octopuses in the wild to learn whether they favor one of their eight arms over the others for certain jobs, but found the creatures give new meaning to ambidextrous. The octopus is ...

Scientists found that the male’s hectocotylus, the specialized arm for mating, is lined with receptors that can sense ...

Scientists set out to understand all the ways the animals use their eight appendages. It wasn’t easy. By Kate Golembiewski The eight arms of an octopus are right there in its name. But these ...

The team's modeling approach is significant to advancement in robotics, dynamics and control systems. The model is in turn used to explain how structural mechanics dramatically simplify the control of ...

Just four different movements make up the 12 distinct arm motions that wild octopuses utilize to achieve complex tasks, like probing rocks for food. Research from the Marine Biological Laboratory (MBL ...

Octopus arms move with incredible dexterity, bending, twisting, and curling with nearly infinite degrees of freedom. New research from the University of Chicago revealed that the nervous system ...

All eight arms of an octopus can be used for whatever their cephalopod owner wishes, but some arms are favored for certain tasks. A new, detailed analysis of how octopuses wield their famously ...
