The Grapsidae are a family of crabs known variously as marsh crabs, shore crabs, or talon crabs.[1] The family has not been confirmed to form a monophyletic group and some taxa may belong in other families.[2] 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 the Varunidae and Plagusiidae.[3] Ten genera remain in the family, two of them known only from fossils:[3]

Geograpsus Stimpson, 1858
Goniopsis De Haan, 1833
Grapsus Lamarck, 1801
Leptograpsodes Montgomery, 1931

Litograpsus † Schweitzer & Karasawa, 2004
