''Carassius ''is a genus in the ray-finned fish family (biology), family Cyprinidae. Most species in this genus are commonly known as Crucian carp, crucian carps, though this term often specifically refers to ''Carassius carassius, C. carassius''. The most well known is the goldfish (''C. auratus''). They have a Eurasian distribution, apparently originating further to the west than the typical carps (''Cyprinus''), which include the common carp (''C. carpio''). Species of ''Carassius'' are not particularly close relatives of the typical carps of ''Cyprinus'', but rather form a more basal (evolution), basal lineage of the subfamily Cyprininae.de Graaf, Martin; Megens, Hendrik-Jan; Samallo, Johannis & Sibbing, Ferdinand A.
