Lobsterman Bill Coppersmith was in for a major surprise last Friday when he noticed an iridescent, opal-like creature in his hull in Maine’s Casco Bay. He had caught a cotton candy lobster, the odds of which are about 1 in 100 million.

Coppersmith, who has been fishing for 40 years, named the lobster “Haddie” after his granddaughter, and immediately alerted Mark Murrell, CEO of the Portland-based seafood company Get Maine Lobster, of his catch. With no intention to sell or cook the lobster, Coppersmith sent Haddie to stay in one of Get Maine Lobster’s tanks while he looked for an aquarium to adopt her.

On Wednesday, Get Maine Lobster confirmed that Haddie had found her permanent home with the Seacoast Science Center in Rye, New Hampshire, which is also home to other rare lobsters.
