    So I don't know how dump of a question this is, but do octos favor a certain arm, as humans do? I think I've read that some animals do, however they have an equal number of right and left handed (as opposed to humans, who are predominantly right handed). So do octos have a arm they prefer to use or do they perhaps rely on certain arms to do different tasks?

    I dont know officially but i notice that all my octos use there front two arms for most tasks, and the rear two arms as anchors( or legs). There is an article or paper that talks about it somewhere. i'll try and find it, unless D knows where it is.
