The Majoidea are a superfamily of crabs which includes the various spider crabs .
Taxonomy [ edit ]
In "A classification of living and fossil genera of decapod crustaceans " De Grave and colleagues divided Majoidea into six families:[1]
The classification has since been revised, with subfamilies Epialtinae and Mithracinae being elevated to families and Hymenosomatidae being moved to its own superfamily. The family composition according to the World Register of Marine Species is as follows:[2]
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
Hyas great spider crab (Hyas araneus ), found in the Atlantic and the North Sea.
Maja squinado
Australian majid spider crab , found off Tasmania, are known to pile up on each other, the faster-moving crabs clambering over the smaller, slower ones.[3]
There is one fossil family, Priscinachidae, represented by a single species, Priscinachus elongatus Cenomanian of France.[4]
