Define ecdysis in biology
WebA spider that has a small abdomen can be undernourished but is mostly because the spider must have recently undergone ecdysis. In long-lived insects, maturation of the organism's structure and the new exoskeleton's coloration might take several days or weeks. Hence sometimes it is hard to identify the organism if it has undergone ecdysis recently. 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 arthropod is described as teneral, a callow; it is "fresh", pal…
