      The oniscidean digestive system has been extensively studied and well described in both slaters and sowbugs (Hames and Hopkin 1989; Štrus et al. 1995). Frequent moulting is an important characteristic of juvenile and adult oniscideans and is related to growth, renewal of the cuticle and reproduction in mature females.
