Having an exoskeleton provides protection against predators and physical damage, but it can also limit flexibility and restrict growth. The rigid outer covering of an exoskeleton provides a strong barrier against threats, but it must be shed and regrown as the organism grows, which can be a time-consuming and energy-intensive process.
