A rare blue-colored red king crab has been caught.
Frank McFarland found the crab in his pot July 4. The crab is being kept alive at the Norton Sound Seafood Center. People show up to have their photos taken with it.
Scott Kent, with the Alaska Department of Fish and Game, says he has no idea why the red king crab is blue. He suspects it's just a mutation.
Kent says a blue crab "turns up once in a blue moon."
Critical thinking challenge: What does once in a blue moon mean? How often is the moon blue?
