@bonifartius Seems there is only one known rotational structure in animals at the macroscopic level... its int he muscles (shell fish) digestive tract.
@freemo
that's quite amazing :)
that wikipedia article looks very interesting, will be a good read this evening! :)
@bonifartius yea its a nice find by the looks of it!
@freemo yeah, that's what i meant :)
@bonifartius if we are defining rotational movement as movements that exceed 360 degrees and can make multiple turns... then I cant think of any other ones...
