EASTHAM - Weighing a pound and three-quarters, Fiona is rare for a 7-year-old, but not because of her girth and weight.With a spotted orange-and-yellow coloration, the lobster is perhaps one in about 30 million, specialists say. Caught in recent weeks off the coast of Prince Edward Island in Canada, the rare crustacean is now in a tank with nearly 100 other lobsters at Arnold’s Lobster and Clam Bar in Eastham.
