In any organism, there are always finite or limited biological resources to allocate to the various functions and organs of the body. For example, if you had two hearts instead of just one, that could help you to survive a heart attack. If your bones were thicker, they would be harder to break. If you had eight eyes instead of two, arranged all around your head, you could see in all directions simultaneously. If your teeth were bigger and sharper, they would be more effective weapons. If your skin were thicker, it would offer more protection. But everything has a cost. The process of evolution produces an organism in which there is a functional cost-benefit ratio for the various design elements of that organism.

Additionally, human epidermis often contains melanocytes responsible for pigmentation, which is not typically present in invertebrate epidermis.
