Invertebrates constitute more than 95% of all known species in the animal kingdom, They play a very important part of the global biodiversity with key species for the structure and function of aquatic and terrestrial ecosystems. In males, it causes the testes to produce a hormone that regulates sperm production.Adrenocorticotropic hormone (ACTH) stimulates the adrenal gland to produce steroid hormones. In their groups, have the students write . The invertebrates form all of the major divisions of the animal kingdom called phyla, with the exception of vertebrates. When they are removed from very young males, the organs that should become testes produce eggs instead of sperm. The corpora allatais surgically removed in the early in development to get adults that are smaller in size. A group of endocrine glands which produces various hormones is called an endocrine system. MF is secreted by the mandibular organ There is some evidence that MF may have a role in larval development by acting as a hormone that retards development (a juvenilizing factor) In adults, MF may function in a reproductive capacity. 27.
