Affiliation 1 Southern Illinois University School of Medicine, Carbondale, Illinois, USA. Glands of ectodermal and endodermal origin produce peptide and amine hormones; mesodermal-origin glands secrete hormones based on lipids. Steroid hormones are not as common - ecdysone is one of the few sterol derived hormones in invertebrates. Growth in Crustaceans Occurs through molting = ecdysis Stages of molting Proecdysis - preparation for molting epidermal cells separate from the old cuticle (apolysis) and divide forming the new exoskeleton Calcium removed from old exoskeleton hepatopancreas - release of energy reserves from storage (animal stops feeding) Ecdysis shedding of the old exoskeleton cuticle is soft - rapid uptake of water Metecdysis Mineral deposition into the new cuticle Endocuticle formation Feeding begins again New tissue formation follows Increased DNA and protein synthesis tissue replaces water Intermolt As skeleton and tissue growth nears completion metabolism is shifted to storage of energy reserves into the hepatopancreas Regulation of many processes is involved Metabolism Water /mineral balance Molting process.
