Biological screw joint

The biological screw joint is a naturally occurring form of the screw joint, a mechanical device that combines rotational movement with single-axis translation. Alexander Riedel of the State Museum of Natural History Karlsruhe and Thomas van de Kamp of the Karlsruhe Institute of Technology[1] discovered it in specimens of Trigonopterus oblongus, a weevil found in Papua.[2]
