The invertebrates form all of the major divisions of the animal kingdom called phyla, with the exception of vertebrates.Invertebrates include the sponges, coelenterates, flatworms, nematodes, annelids, arthropods, molluscs, and echinoderm. Effects of TBT on Crassostrea gigas mollusks The first adverse effects of TBT on mollusks were observed in Crassostrea gigas at the Bay of Arcachon, one of the European centers of oyster aquaculture, with ball-shaped shell deformations in adults and a decline of annual spatfall [11]. Chemically, most ecdysones are the same as the active hormone of insects (20-hydroxyecdysone) and can cause molting in crustaceans and insects.

As You know: Invertebrates are animals without a backbone. 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. There is some evidence also for the existence of a molt-accelerating hormone of neural origin, whose actions may parallel that of the insect brain hormone. Hypothalamus Gland.
