The blackfin jumper, or Moxostoma cervinum, is a freshwater fish from the sucker family. It lives in rivers of southeastern North America and can jump out of the water when in danger.
The blackfin jumper differs from other suckers by black fin tips. It is important for river ecosystems because it processes bottom sediments and serves as food for larger fish.
Collects food with its lower mouth-sucker from stones and ground.
Immature form that undergoes metamorphosis before adulthood.
