Galatheoidea
Encyclopedia
Galatheoidea is a superfamily of decapod
crustacean
s comprising some squat lobster
s and the porcelain crab
s. Two other families of squat lobsters, Chirostylidae and Kiwaidae
, are not closely related to the members of Galatheoidea, and are now placed in other superfamilies. The fossil record of the group extends back to the Middle Jurassic
genus Palaeomunidopsis.
The following genera are included:
Galatheidae Samouelle, 1819
Munididae Ahyong et al., 2010
Munidopsidae Ortmann, 1898
Porcellanidae Haworth, 1825
Two further fossil taxa may be included in the superfamily, but were not considered in the latest synopsis. The family Retrorsichelidae contains the single species, Retrorsichela laevis from the Campanian
, which was tentatively placed in Galatheoidea by its authors. The Eocene
genus Ovocarcinus, containing only O. elongatus, was originally placed incertae sedis
.
Decapoda
The decapods or Decapoda are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crayfish, crabs, lobsters, prawns and shrimp. Most decapods are scavengers. It is estimated that the order contains nearly 15,000 species in around 2,700 genera, with...
crustacean
Crustacean
Crustaceans form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 50,000 described species range in size from Stygotantulus stocki at , to the Japanese spider crab with a leg span...
s comprising some squat lobster
Squat lobster
Squat lobsters are decapod crustaceans of the families Galatheidae, Chirostylidae and Kiwaidae, including the common genera Galathea and Munida. They are not lobsters at all, but are more closely related to porcelain crabs, hermit crabs and then, more distantly, true crabs...

Porcelain crab
Porcelain crabs are decapod crustaceans in the widespread family Porcellanidae, which superficially resemble true crabs. They are typically less than wide, and have flattened bodies as an adaptation for living in rock crevices...
