Some genera previously included in the family are now treated as members of separate families in the superfamily Ocypodoidea, such as the Dotillidae and Macrophthalmidae. In 2016, the genus Uca was split into 13 genera by elevating its subgenera to genus rank, among other things.[1] Further refinements have been made to the organization of the family, which has 4 subfamilies, about 13 extant genera, and about 180 described species as of 2020.[2][3][4]

The majority of the Ocypodidae species are fiddler crabs, the exceptions being the members of the genus Ocypode, ghost crabs, and the genus Ucides, mangrove crabs.[2][3]


These genera belong to the family Ocypodidae:[2][5][6]
