(CNN) — A fisherman off the coast of Maine pulled in an incredibly rare two-toned lobster on Friday. It's a one in 50 million find.

The lobster's color is bifurcated straight down the middle -- meaning it's partly black and partly red. The unique color pattern is likely due to a rare genetic mutation, fisheries scientist Matt Thaluhauser said.

Captain Daryl Dunham, the fisherman who found the two-toned crustacean near Stonington, a cluster of islands southwest of Bar Harbor, is donating it to the Maine Center for Coastal Fisheries.

It won't be alone.

The bicolored male will complete a quartet of colorful crustaceans already on display at the Maine center. He'll live with two calico lobsters -- they're one in 30 million -- and a blue lobster that's one in 2 million.

Oh, and in case you're counting -- the odds of this crew all sharing a tank together are around one in 90 octillion, the scientist said.
