Antidiuretic hormone (ADH) and oxytocin are produced in the hypothalamus and transported by axons to the posterior pituitary where they are dumped into the blood. 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
