A genetic mutation occasionally occurs in lobsters that creates an excessive amount of a particular protein, giving them a vibrant blue exoskeleton. Though blue lobsters are rare, they aren't uncommon either. An estimated 2 million lobsters are blue. Having a Smurf-like complexion isn't necessarily a bad thing if you're a lobster, either. They are often spared from the cooking pot due to their unusual coloration.
A lobsterman in Plymouth, Massachusetts, recently pulled up one of these sapphire-hued crustaceans. It weighed two pounds and was nicknamed Bleu, according to The Boston Globe.
