Galatheoidea
The Galatheoidea are a superfamily of decapod crustaceans comprising the porcelain crabs and some squat lobsters. Squat lobsters within the three families of the superfamily Chirostyloidea are not closely related to the squat lobsters within the Galatheoidea. The fossil record of the superfamily extends back to the Middle Jurassic genus '' Palaeomunidopsis''. Classification These families and genera are included: ;Galatheidae Samouelle, 1819 *† ''Acanthogalathea'' Müller & Collins, 1991 – Upper Eocene * ''Alainius'' Baba, 1991 * ''Allogalathea'' Baba, 1969 * ''Allomunida'' Baba, 1988 * ''Coralliogalathea'' Baba & Javed, 1974 * ''Fennerogalathea'' Baba, 1988 * ''Galathea'' Fabricius, 1793 * ''Janetogalathea'' Baba & Wicksten, 1997 * ''Lauriea'' Baba, 1971 *† '' Lessinigalathea'' De Angeli & Garassino, 2002 – Lower Eocene *† '' Lophoraninella'' Glaessner, 1945 – Upper Cretaceous *† '' Luisogalathea'' Karasawa & Hayakawa, 2000 – Upper Cretaceous * '' Macrothea'' M ...

Squat Lobster
Squat lobsters are dorsoventrally flattened crustaceans with long tails held curled beneath the cephalothorax. They are found in the two superfamilies Galatheoidea and Chirostyloidea, which form part of the decapod infraorder Anomura, alongside groups including the hermit crabs and mole crabs. They are distributed worldwide in the oceans, and occur from near the surface to deep sea hydrothermal vents, with one species occupying caves above sea level. More than 900 species have been described, in around 60 genera. Some species form dense aggregations, either on the sea floor or in the water column, and a small number are commercially fished. Description The two main groups of squat lobsters share most features of their morphology. They resemble true lobsters in some ways, but are somewhat flattened dorsoventrally, and are typically smaller. Squat lobsters vary in carapace length (measured from the eye socket to the rear edge), from in the case of ''Munidopsis aries'', down to o ...

Porcelain Crab
Porcelain crabs are decapod crustaceans in the widespread family Porcellanidae, which superficially resemble true crabs. They have flattened bodies as an adaptation for living in rock crevices. They are delicate, readily losing limbs when attacked, and use their large claws for maintaining territories. They first appeared in the Tithonian age of the Late Jurassic epoch, 145–152 million years ago. Description Porcelain crabs are small, usually with body widths less than . They share the general body plan of a squat lobster, but their bodies are more compact and flattened, an adaptation for living and hiding under rocks. Porcelain crabs are quite fragile animals, and often shed their limbs to escape predators, hence their name. The lost appendage can grow back over several moults. Porcelain crabs have large chelae (claws), which are used for territorial struggles, but not for catching food. The fifth pair of pereiopods is reduced and used for cleaning.

Chirostyloidea
Chirostyloidea is an anomuran superfamily with squat lobster-like representatives. It comprises the three families Chirostylidae, Eumunididae and Kiwaidae. Although representatives of Chirostyloidea are superficially similar to galatheoid squat lobsters, they are more closely related to Lomisoidea and Aegloidea together forming the clade Australopoda. No fossils can be confidently assigned to the Chirostyloidea, although '' Pristinaspina'' may belong either in the family Kiwaidae or Chirostylidae.

Munididae
The Munididae are a family of squat lobsters, taxonomically separated from the family Galatheidae in 2010. Description and ecology The squat lobsters in the family Munididae can be distinguished from other families by the presence of a trispinose frontal edge to the carapace, as well as a central rostrum, and two spines extend forward from above the eyes. Although a few species enter shallow water, the majority of species in the Munididae are deep-water taxa, in contrast to the mostly shallow-water Galatheidae. Taxonomy The genera now included in the family Munididae had previously been included in a wider Galatheidae. When originally described , the family contained these genera: *'' Agononida'' Baba & de Saint Laurent, 1996 *''Anomoeomunida'' Baba, 1993 *'' Anoplonida'' Baba & de Saint Laurent, 1996 *'' Babamunida'' Cabezas, Macpherson & Machordom, 2008 *'' Bathymunida'' Balss, 1914 *''Cervimunida'' Benedict, 1902 *† '' Cretagalathea'' Garassino, De Angeli & Pasini, 2008 ...

Decapoda
The Decapoda or decapods (literally "ten-footed") are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crabs, lobsters, crayfish, shrimp and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp (about 3,000 species) and Anomura including hermit crabs, porcelain crabs, squat lobsters (about 2500 species) making up the bulk of the remainder. The earliest fossil decapod is the Devonian ''Palaeopalaemon''. Anatomy Decapods can have as many as 38 appendages, arranged in one pair per body segment. As the name Decapoda (from the Greek , ', "ten", and , '' -pod'', "foot") implies, ten of these appendages are considered legs. They are the pereiopods, found on the last five thoracic segments. In many decapods, one pair of these "legs" has enlarged pincers, called chelae, with the legs be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
