单词	brachyuran
释义	brachyuran /ˌbrakēˈyo͝orən / noun A crab belonging to the brachyura suborder of crustaceans.This feature is present in crayfish, thalassinids, and anomalans but is presumably lost in brachyurans.... The taxon is unique among brachyurans due to its distinctive dorsal carapace ornamentation. Based upon the morphology of the chela and appendages and the orientation of the appendages with respect to the carapace, the new material is not referable to any macruran groups and must be a brachyuran.
