US EditionOctopus arms are adaptable but some are favored for particular jobs
Researchers observed 25 wild octopuses performing nearly 4,000 arm actions, finding front arms used 64% for exploration and manipulation, while rear arms aid locomotion and support.
- Octopuses can use any arm for tasks, but tend to use the front arms more for exploring and the rear arms for locomotion .
- Octopuses show no preference for using their left or right limbs, unlike humans.
- The study analyzed video clips of octopuses in the Atlantic Ocean and Caribbean Sea taken between 2007 and 2015.

octopuses do not use all their eight arms equally, but they use some preferred for certain activities. Scientists have found this out - and robot development could also benefit from it.
Why do octopuses use the forearms when exploring and when crawling the forearms? Researchers have analysed the behavior of the animals in detail.
The front arms are often used to explore the rear to move around. Robot development could benefit from these findings.
Unlike humans, octopuses coordinate not only two but eight arms with suction cups. A video analysis now shows: Depending on the task, they prefer to use other limbs.
