Cancridae

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 †Lobocarcininae Beurlen, 1930 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.
