We all know the primary purpose of a lobster shell. Because a lobster’s body is soft and vulnerable, the exoskeleton or carapace is the lobster’s main source of protection. The hard shell acts as armor against predators and physical damage.
But once the delicious Maine lobster meat has been extracted and the shells lie in a heap in a bowl, what other uses would one have for them? Turns out, there are a variety of secondary uses for lobster shells you probably didn’t even know about!
