Majoidea is a superfamily of crabs which includes the various spider crabs. It comprises five or six Recent families:[1]

The families "Pisidae" and "Tychidae" are now treated as the subfamilies Pisinae and Tychinae of the family Epialtidae, and "Mithracidae" is now treated as the subfamily Mithracinae of the family Majidae.[1]

Notable species within the superfamily include:

  • Japanese spider crab (Macrocheira kaempferi), the largest living species of crab, found on the bottom of the Pacific Ocean.
  • Libinia emarginata, the portly spider crab, a species of crab found in estuarine habitats on the east coast of North America.
  • Hyas, a genus of spider crabs, including the great spider crab (Hyas araneus), found in the Atlantic and the North Sea.
  • Maja squinado, sometimes called the "European long leg crab or pie faced crab" because of the way its face is shaped.

There is one fossil family, Priscinachidae, represented by a single species, Priscinachus elongatus, from the Cenomanian of France.[3]
