Cancridae is a family of crabs. It comprises six extant genera, and ten exclusively fossil genera, in two subfamilies:
Extant Genera Cancrinae Latreille, 1802 Anatolikos Schweitzer & Feldmann, 2000 Cancer Linnaeus, 1758 Glebocarcinus Nations, 1975 Metacarcinus A. Milne-Edwards, 1862 Platepistoma Rathbun, 1906 Romaleon Gistel, 1848
Fossils Cancrinae Latreille, 1802 †Anisospinos Schweitzer & Feldmann, 2000 †Ceronnectes De Angeli & Beschin, 1998 †Cyclocancer Beurlen, 1958 †Microdium Reuss, 1867 †Notocarcinus Schweitzer & Feldmann, 2000 †Santeecarcinus Blow & Manning, 1996 †Sarahcarcinus Blow & Manning, 1996 †Lobocarcininae Beurlen, 1930 †Lobocarcinus Reuss, 1857 †Miocyclus Müller, 1978 †Nicoliscarcinus Beschin, Busulini, Tessier & Zorzin, 2016 †Ramacarcinus De Angeli & Ceccon, 2017 †Tasadia Müller in Janssen & Müller, 1984 Until 2000, the extant species were all classified in genus Cancer. After an analysis of new fossil material, the subgenera were elevated to the rank of genus, and three new genera were erected. Most of the family's current diversity is found in temperate waters of the Northern Hemisphere.
