Jumbo Lump: Jumbo lump crab is easily recognizable because the name describes it perfectly. Jumbo lump crabmeat comes from the crab's swimmer fin muscles and because crabs only have two, there's not much to be had from an average crab. It's a creamy white color and is the most expensive grade. You may also see it labeled "colossal." Lump:  Lump crab meat is also creamy white, but has smaller flakes than jumbo lump. It comes from the body of a crab, works well for crab cakes and is less expensive than jumbo. Backfin:  Backfin crab meat, also known as "special" crab meat, is also off-white and comes from the body of a crab. It's very flaky and also works for crab crakes. Claw:  Claw meat is dark in color with a strong flavor. It's the least expensive and can be used for crab cakes, but you won't have the lovely creamy color.
