Description

The leather carp, also called nude carp, is the almost scaleless form of the common carp (Cyprinus carpio). Its thick, leathery skin is bare, apart from at most a few scales near the dorsal fin or tail root. It is not a mirror carp without scales: the form arises from a different genetic combination, with the same N allele that also produces the linear carp and lowers viability. Leather carp are the rarest carp form in Dutch waters. Otherwise the leather carp lives like any carp: a bottom-rooting omnivore of still and slow-flowing, nutrient-rich water that can reach about 120 cm.
