3.1. Crab moult stage and morphometric features
An observation of the exopodite tips demonstrated that the crabs used in this study were all in the intermoult stage. Indeed, many setae and chromatophores were visible (Fig. 2A), and the epidermis appeared closely joined to the cuticle without any epidermal retraction (Fig. 2B,C).
