The emerald shiner is a small freshwater fish up to 10 centimeters long. It has a silvery body with a bright green stripe along its side that shimmers in the water.
The emerald shiner plays an important role in water bodies as food for large predatory fish. Large schools of this fish help transport nutrients and serve as an indicator of water purity.
Immature form that undergoes metamorphosis before adulthood.
