Quillback, or Carpiodes cyprinus, is a freshwater fish from the sucker family. It lives in rivers and lakes of North America and has a very long first ray in the dorsal fin that resembles a feather.
Quillback differs from other suckers by its very long first ray of the dorsal fin. This fish is important for nature because it processes detritus on the bottom of water bodies and serves as food for predatory fish.
Immature form that undergoes metamorphosis before adulthood.
