Natural History Wanderings

Nature News has a  story that explains how is it an octopus never gets tangled up with itself. Each of the octopus’s arms has hundreds of suckers that reflexively to almost anything they come into contact with — but never grasp the octopus itself, even though an octopus does not always know what its arms are doing.

Scientists describe that each arm has its own motor controller separate from the brain that through chemical sense and touch is able to identify its own body and not grasp it. This even applied to amputated arms.
