Octopuses Tend to Use Particular Arm, or Arms, for Specific Tasks

New research provides a comprehensive look into how wild octopuses use their arms in natural habitats. By analyzing arm movements across diverse environments, this is the first study to relate arm movements to whole animal behaviors in complex, real-world settings. The findings reveal that every arm is capable of performing all action types; however, there was a clear...
