Arthropod - Exoskeleton and molting Britannica

Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa. Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed. The remnants of the old, empty exoskeleton are called exuviae. After moulting, an … Zobacz więcej The term ecdysis comes from Ancient Greek ἐκδύω (ekduo) 'to take off, strip off'.
