There are some hormones that are only found in invertebrates such as arthropods and are not shared with vertebrates. For example, the steroid hormone ecdysone controls molting in arthropods. Ecdysone is produced by special molting glands in arthropods. Factors such as environmental conditions and internal signals cause hormone-secreting cells in the brain to act on the molting gland to release ecdysone.
