The orangespotted sunfish (Lepomis humilis) is a North American species of freshwater fish in the sunfish family (Centrarchidae). These fish are widely distributed across the middle and eastern United States, from the Rocky Mountains to the east, from the Great Lakes south into the Gulf Coast. The orangespotted sunfish is ecologically unique and thrives in turbid, shallow systems that have few predators and low oxygen contents. The species prefers vegetated areas in sluggish backwaters or lakes, and can also be found in turbid rivers. The orangespotted sunfish can extend its range in lower-quality waters, which is not characteristic to other sunfish. Orangespotted sunfish vary in total length and age for different river basin originations, but can be found to live four to seven years, and recorded lengths are up to 15 cm (5.9 in). Males make grunting noises to attract females to mate. and are known to nest in ‘colonies’ or aggregations. Spawning patterns are similar to those of other sunfish. Due to the wide distribution of this fish, the species is not endangered and management plans are almost nonexistent presently. The orangespotted sunfish has been introduced to many habitats, such as rivers in Florida, Alabama, Texas, Colorado, Michigan, and Canada.
