He initially thought he had captured an albino lobster, but on closer inspection realised his catch was a unique blue and cream colour.

“This one was not all the way white and not all the way blue,” he told The Portsmouth Herald.

“I’ve never seen anything like it. Usually, the stronger lobster are usually the reddish brown colour but this one had a hard shell.”

He gave the rare crustacean to the Seacoast Science Center to study and put on display.

Last year, a massive 'sea monster' lobster was caught by a stunned fisherman after a hurricane.
