Yep. If you look carefully at a most starfish, you can see that they are bilaterally symmetric. For example, when there are five legs, if you mentally halve the animal along a leg, only one of the five legs results in both sides matching.
- gowld 7y agoThat still undermines the articles thesis and that an odd leg can't be bilateral.
- kittiepryde 7y agoI have one head and four appendages (two for each side, but only one head bilateral down the middle). I don't see why they couldn't have a leg, bilateral down the middle ( like a head?)

- smackay 7y agoAnyone know if there is "handedness" in tails, particularly in monkeys where they use their tails while climbing. Do individuals always curl their tails clockwise or anticlockwise around a branch?
- e12e 7y agoWell, technically you have a tail too. I suppose a better description would be a spine, stunted in one end (tailbone), extended at the top (head), with two set of limb pairs (arms, legs).
- matt-attack 7y agoWell said and excellent point.
