The structure of the more active and most predominant form of the hormone was subsequently determined to be 20-hydroxyecdysone (20E). The endocrine systems of some animal phyla have been studied in detail, but the endocrine systems of only a few species are well known. Nemertine worms are primitive marine animals that lack a coelom (body cavity) but differ from other acoelomates (animals that lack a coelom) by having a complete digestive tract. Endocrine Disruptors Certain compounds are likely to act as endocrine disruptors not only by a direct binding to receptorsacting as hormone-mimics (agonists) or as antihormones (antagonists)but also indirectly by modulating endogenous hormone levels by interfering with biochemical processes associated with the production, availability, or metabolism of hormones or also by the modulation of receptors.
