The 16 main groups of millipedes (Diplopoda) show great differences in the appearance of their legs, which can consist of 6, 7, or 8 joints. In this project the leg musculature of millipede species belonging to all 16 extant main millipede groups (orders) will be studied comparatively for the first time. This study will be conducted in the course of a Master thesis by TIm Dannenfeld as part of the international Master OEP programme of the University of Bonn.
