Examples of representatives in Euarthropoda with grasping structures. A Red swamp crayfish Procambarus clarkii (Decapoda: Astacidae), anterior view, with chela, one-fixed-finger-one-movable-finger configuration; simplified after Kranking (2018, pp. 6–7). B Anterior body of praying mantis Hierodula transcaucasica (Dictyoptera: Mantodea), ventral view, with sub-chela, jackknife configuration; simplified after Ehrmann and Borer (2015, Fig. 35 right, p. 257). C Head of larva of an owllion (Neuroptera: Myrmeleontiformia), dorsal view, two-movable-fingers configuration of the mouthparts (stylets); based on specimen ZMH 62882 (collection of the Centrum für Naturkunde (CeNak), Leibniz-Institut zur Analyse des Biodiversitätswandels (LIB), Hamburg). D Head of a dragonfly larva (Odonatoptera: Odonata), ventro-lateral view, two-movable-fingers configuration of the palps of the labium (“mask”); simplified after Haug (2020, Fig. 4, p. 182). E Earwig (Polyneoptera: Dermaptera), dorso-lateral view, two-movable-fingers configuration of the cerci; simplified after Országh et al., (2010, fig. on title page)
