An exoskeleton is a hard external skeleton that provides protection and support for the organism. Most invertebrates have exoskeletons. Like on the insect above the exoskeleton presents places of attachment for the muscles that move the appendages. In the early stages of an insect’s life it needs to molt or shed its exoskeleton because of its frequent growth spurts. Depending on the type of insect, shedding of the exoskeleton can occur 5 to 60 times in a single life span. When an exoskeleton is first shed it is soft and vulnerable, but as it matures and exposed to the elements of nature, it hardens.
