During proecdysis the ecdysone is already there - it has already been produced. When they are removed from very young males, the organs that should become testes produce eggs instead of sperm. The crustaceans are extremely diverse and species-rich group of arthropods as do insects and other arthropods. In other . Advances in the study of invertebrate endocrine systems have lagged behind those in vertebrate endocrinology, largely due to the problems associated with adapting investigative techniques that are appropriate for large vertebrate animals to small invertebrates.

As simple sugars, these are absorbed from the GE system into the body. The endocrine system is composed of glands that synthesize and secrete products, called hormones, directly into the blood rather than through a duct. Osmoregulation is the process of physiological adjustment of the volume of water and the concentrations of solutes in the cells and body fluids of organisms, including the vertebrates. annelids.
