Octopuses don’t have a dominant arm and their four front limbs lead exploration

They’re split into explorer front arms and mover rear arms

New field research suggests octopuses, unlike humans, don’t rely on a single dominant arm. Instead, they tend to use their front four arms for exploring and their rear arms more often for movement. The findings point to a flexible, redundant limb system that helps octopuses adapt and multitask in their natural habitats.
