If you're feeling blue there's a lobster that can match your mood in Massachusetts. Arnold's Lobster & Clam Bar in Eastham, says someone brought in a blue lobster that they caught in the Atlantic Ocean. The restaurant is keeping the lobster on display, inviting members of the public to come visit it until it is either freed back into the ocean or is donated to the New England Aquarium. The University of Maine's Lobster Institute said only about one in two million lobsters feature the unusual blue coloration, which results from a genetic defect.
