Molting occurs in all animals with exoskeletons, due to the fact that such animals cannot grow bigger than their shell without replacing their shell with a bigger one. That is the general idea
Molting occurs in animals with exoskeletons because their rigid outer shell does not grow. To accommodate growth, these animals shed their old exoskeleton and create a new, larger one. This process is controlled by specific hormones and is crucial for their development and survival.
