The '''Grapsidae''' are a [family](/source/Family_(taxonomy)) of [crab](/source/crab)s known variously as '''marsh crabs''', '''shore crabs''', or '''talon crabs'''.<ref name="ITIS"/> The family has not been confirmed to form a [monophyletic group](/source/monophyletic_group) and some [taxa](/source/Taxon) may belong in other families.<ref name="Schubart">{{cite journal |author1=C.

==Genera==
A number of taxa, formerly treated as [subfamilies](/source/subfamily) of the family Grapsidae are now considered [families](/source/Family_(taxonomy)) in their own right, including the [Varunidae](/source/Varunidae) and [Plagusiidae](/source/Plagusiidae).<ref name="Grave">{{cite journal|journal=[Raffles Bulletin of Zoology](/source/Raffles_Bulletin_of_Zoology) |year=2009 |volume=Suppl. 21 |pages=1–109 |title=A classification of living and fossil genera of decapod crustaceans |author1=Sammy De Grave |author2=N.
