Orangespotted Sunfish

Orangespotted Sunfish

The Orangespotted Sunfish is one of the smallest members of the sunfish family found throughout Illinois, a native species that is common statewide and thrives in conditions that challenge other sunfish - they have exceptional tolerance for turbid, shallow waters with low oxygen content and high pollution levels.

Scientific Name: Lepomis humilis

Physical Characteristics:
  • Typically averaging 4 inches in length with a maximum of about 6 inches.
  • Their compressed body features distinctive rust-colored or orange spots on the lower sides, with breeding males displaying vibrant red eyes and orange-red coloration.
  • The species has a relatively large mouth that extends to the front of the eye.
  • The species displays remarkable phenotypic plasticity - those feeding on small planktonic prey develop more elongated bodies with angled snouts, while those eating larger prey form deeper bodies with blunt snouts.

What to know

Habitat Distribution

  • Common statewide throughout Illinois.
  • Prefer backwaters, overflow pools, slow-moving streams, and areas with little current, often inhabiting waters too degraded for other sunfish species.

Key Locations

  • Mississippi and Illinois rivers, the Kankakee River system and similar floodplain waters.

Specific Spots

  • Focus on turbid backwaters, overflow pools along rivers, and shallow areas of lakes and ponds with minimal current.
  • Target areas with scattered cover like fallen branches, wood piles, and vegetation edges in 1-3 feet of water.
