                                A 3-ounce serving of cooked snow crab claws contains just 60 calories, while a single bear claw pastry can pack over 500 calories. The question of how many calories are in a claw depends entirely on the type of food you are referring to, with vast differences between a seafood entree and a bakery treat.
