Molting from "summary" of BEAUTIFUL SWIMMERS by WILLIAM W. WARNER
"Molting is the crab's means of growth and renewal. It is a process that all crabs must undergo throughout their lives, shedding their outer shell in order to make room for new growth. This shedding of the shell, or exoskeleton, is a necessary and transformative process, allowing the crab to grow larger and develop new tissues. The process of molting is a vulnerable time for the crab, as they are left soft and unprotected until their new shell hardens. During molting, the crab's body secretes enzymes that soften the old shell, allowing it to be shed. The crab then wriggles out of its old shell, leaving behind a perfect replica of its former self. Once free of the old shell, the crab is left in a delicate state, with its new shell still soft and pliable. It is during this time that the crab must retreat to a safe place, away from predators, to allow its new shell to harden. The frequency of molting varies among different species of crabs, with some molting more frequently than others. Young crabs may molt several times a year, while older crabs may only molt once a year. The process of molting is a crucial aspect of a crab's life cycle, allowing them to grow, regenerate lost limbs, and reproduce. Molting is a natural and necessary process for crabs, allowing them to continue growing and thriving in their environment. It is a process that requires patience, vulnerability, and resilience on the part of the crab. Through molting, the crab is able to shed its old self and emerge renewed, ready to face the challenges of its environment with a fresh perspective and a strengthened shell."
