Grapsidae is a family of crabs known variously as ''marsh crabs'', ''shore crabs'' or ''talon crabs''.〔 It is not confirmed that the family forms a monophyletic group and some taxa may belong in other families. They are found along the shore among rocks, in estuaries, marshes, and in some cases pelagic among drifting seaweeds and flotsam. ==Genera== A number of taxa, formerly treated as subfamilies of the family Grapsidae are now considered families in their own right, including Varunidae and Plagusiidae. Ten genera remain in the family, two of them known only from fossils:〔 *''Geograpsus'' Stimpson, 1858 *''Goniopsis'' De Haan, 1833 *''Grapsus'' Lamarck, 1801 *''Leptograpsodes'' Montgomery, 1931 *''Leptograpsus'' H. Milne Edwards, 1853 *''Litograpsus'' † Schweitzer & Karasawa, 2004 *''Metopograpsus'' H. Milne Edwards, 1853 *''Miograpsus'' † Fleming, 1981 *''Pachygrapsus'' Randall, 1840 *''Planes'' Bowdich, 1825 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Grapsidae」の詳細全文を読む スポンサード リンク
