How does an orangespotted sunfish eat?

The orangespotted sunfish feeds primarily on small invertebrates, such as zooplankton, crustaceans, and insect larvae. It uses its small, protrusible mouth to suction in prey, often hovering in the water column or near the substrate. The sunfish may also filter feed by swimming with its mouth open to capture suspended food particles. This feeding strategy allows it to efficiently harvest food in its freshwater habitat.
