Carp

Carp are freshwater fishes commonly associated with rivers, lakes and ponds, including the common carp and related forms. Many search the bottom for plant material, invertebrates and other foods. Mouth shape and feeding habits vary within the broad common-name grouping. Common carp have barbels near the mouth that assist investigation of food. Domestic ornamental koi are forms of carp selected for color and pattern. Introduced carp can alter habitats through their feeding and movements, though effects depend on the species and setting.
