Two lobstermen in Maine have caught a pair of rare albino lobsters within a week.

Bret Philbrick caught the crustacean off of Owls Head on Thursday and Joe Bates caught one off the Rockland breakwater days earlier.

Albino lobsters are believed to be about one in 100 million.

“The chances of catching an albino lobster is only one in 100 million,” announced the Lobster Institute at the University of Maine.

“That white is the rarest of all the lobster’s color mutations. You see all different shades of blue, yellow. I’ve seen blue. I think that’s the rarest one you can find”, added Alexandra Knight, from the Owls Head Lobster Company

The lobsters are in a crate at Owls Head Lobster Co. One of the lobsters will go to the Maine State Aquarium in Boothbay Harbor and the other to Brooks Trap Mill in Thomaston.

The lobsters are below the legal size, which normally means that they had to be returned to the ocean so they could mature for another one to two years but the Marine Patrol made an exception.

Bates also caught a one-in-30 million yellow lobster on Monday.

Earlier this year, one lobsterman caught a calico lobster which sported bright orange and dark blue spots in New Hampshire. The lobster is the second rarest of lobsters, according to an Explore the Ocean World Oceanarium spokesperson. A bright yellow lobster, whose origin isn’t known, was also bought from a supermarket in Florida.

University of Maine’s Lobster Institute executive director Bob Bayer said that some unusual breeding may be happening if more similar-looking lobsters turn up in the area.

As for the lobsters caught this week, Bayer said he would like to see them stay around for a while and get fed food high in carotenoids, like crab and periwinkles. Such food will darken the shell, if they’re not albino.
