Cyprinus carpio carpio is a subspecies of the common carp that is commonly found in Europe. They are native to much of Europe and can also be found in the Caucasus and Central Asia. Mitochondrial DNA analysis shows a difference between C. carpio carpio and Cyprinus rubrofuscus. They are omnivorous in nature and feed on mollusks, insects, crustaceans and seeds. Though dark in color, there are some wild caught specimens which are colored orange. This subspecies has also been domesticated in European ponds for hundreds of years. They are considered as a naturalized species in most US states.
