PLYMOUTH, Mass. – A Massachusetts lobsterman made an incredibly rare catch while fishing off the coast of Cape Cod.

Wayne Nickerson, owner and captain of the FV Windsong in Plymouth, spotted the lobster in his trap on Monday.

His wife, Jan Nickerson, posted a photo of the lobster on the Old Colony Memorial Facebook page, and it has been shared more than 1,900 times.

“He let out a loud exclamation of excitement,” Jan told ABC News. “He was very clear about how excited he was.”

The 2-pound rare blue lobster was only the second one Wayne has caught in his 35-year career.

The first time he caught one was in 1990.

According to the Lobster Institute at the University of Maine, “only an estimated one in 2 million lobsters is blue.”

“The lobster went to a nice cool tank, so he wouldn’t die. He is fine, healthy and happy,” Jan said in a comment.

Jan said the couple hopes to be able to share the lobster – named “Bleu” – with a local aquarium.
