    • GDESC:  頭胸甲近圓方形,甲面稍隆。額緣呈波浪形四短鈍齒,兩側齒較尖銳。前側緣含眼窩外齒共四齒,大小由前往後依序遞減,末齒僅留痕跡或為不明顯小刺。螯足掌部內、外側面密生絨毛,並擴生至指節基部及腕節末部。步足的長、腕節背緣及末兩節的背、腹緣均具剛毛。全身呈墨綠至黑褐色,步足指節末端乳白色至米黃色。最大體型甲寬7公分。本種蟹為有名的食用蟹,但為肺吸蟲的第二中間宿主,食用前必須充分煮熟,以免病從口入。
        分布於東亞,台灣、廣東、福建、日本及朝鮮半島均有發現。成蟹棲息於淡水河川,於秋冬之際降河入海交配繁殖,每逢繁殖期在河口域潮間帶均可發現,常藏身於岩石下。孵出的幼體在海中發育至大眼幼體後,即溯溪而上回到河川成長。
