Well-fed D. magna undergo their first ecdysis about 20 h after their release from the brood chambers of their mothers (Anderson and Jenkins, 1942; Anderson, 1946). Some carapaces were observed on the bottom of the beaker after 24 h. The D. magna were checked for ecdysis 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.
