anomura การใช้

• Among the Anomura, there is considerable variation in the number of larval stages.
• The larvae of Dromiacea resemble those of the Anomura more closely than those of other crabs.
• Once considered the oldest true crab, it is now considered to be an early member of the Anomura.
• It is the oldest known fossil from the infraorder Anomura, and is most closely related to " Eocarcinus praecursor ".
• From 1988 to 1998, supported by subsequent programs of CNR, she studied Brachyura and Anomura from the East African mangrove swamps.
• There is wide acceptance from molecular data that Anomura and Brachyura ( true crabs ) are sister taxa, together making up the clade Meiura.
• The oldest fossil attributed to Anomura is " Platykotta ", from the Norian Rhaetian ( Late Triassic ) Period in the United Arab Emirates.
• In the Anomura ( hermit crabs and related animals ), the fifth pair of pereiopods is often hidden inside the branchial chamber, where they are used to clean the gills.
• The superfamily Eocarcinoidea, containing " Eocarcinus " and " Platykotta ", was previously considered to be a member of the Dromiacea, but has since been transferred to the Anomura.
• Although they are classified as crabs, the larvae of Dromiacea are similar to those of the Anomura, which led many scientists to place dromiacean crabs in the Anomura, rather than with the other crabs.
• Although they are classified as crabs, the larvae of Dromiacea are similar to those of the Anomura, which led many scientists to place dromiacean crabs in the Anomura, rather than with the other crabs.
• "Porcellanopagurus " is unusual among hermit crabs in that the body is largely L . A . Borradaile interpreted " Porcellanopagurus " as being an independent instance of carcinisation among the Anomura.
• Any organs which are absent from the adults do not generally appear in the larvae, although there are a few exceptions, such as the Lucifer ", and some pleopods in certain Anomura and crabs.
• Members of the family Aeglidae and " Clibanarius fonticola " are also restricted to freshwater, but these " crab-like " crustaceans are members of the infraorder Anomura ( true crabs are Brachyura ).
• There certainly should be one " main " page for " Crab "; the present page may be well-written; I don't know to what extent its remarks apply only to Brachyura or to Anomura as well; perhaps this should be addressed in the main article.
• The decapods are further subdivided on the basis of the gill structure into two suborders Dendrobranchiata ( prawns ) and Pleocyemata, which is further subdivided into several infraorders, such as the Caridea ( " true shrimp " ), the Stenopodidea ( boxer shrimp ) and the Anomura and the Brachyura ( crabs ) and so forth.
