Hermit Crab Molting Explained | The Biology Behind the Process
What Is Molting? Molting (ecdysis) is the biological process by which a crustacean sheds its exoskeleton in order to grow. Land hermit crabs, like all arthropods, do not grow continuously. Their rigid outer shell must be replaced periodically with a larger one. Molting is not a single event. It is a hormonally regulated, multi-stage physiological cycle involving the nervous system, endocrine system, epidermis, and internal tissues. Understanding molting properly requires understanding the internal control system that drives it. The Hormonal Control of Molting Molting is regulated by a balance between inhibitory and stimulatory hormones. The key components are: The X-organ–sinus gland complex in the eyestalk produces Molt-Inhibiting Hormone (MIH), which suppresses molting during the intermolt phase. TheRead More →
