Micropterus punctulatus, commonly known as the spotted bass, is a freshwater fish native to North American rivers and lakes. It features a robust body with a dark lateral stripe and distinct spots on the lower sides. Known for its aggressive feeding habits, it thrives in clear, warm waters with rocky or gravelly substrates.

Micropterus punctulatus, commonly known as the spotted bass, is native to North America. It is predominantly found in the central and southeastern United States. Its geographical distribution includes the Mississippi River basin, extending from southern Ohio and West Virginia to southeastern Kansas and northeastern Texas, and southward into the Gulf Coast drainages.

The spotted bass typically inhabits freshwater environments such as rivers, streams, and reservoirs. It favors clear, slow-moving waters with moderate to low current and is often found in areas with rocky or gravelly substrates. The species thrives in temperate climates, where water temperatures range from 10°C to 28°C (50°F to 82°F).

Spotted bass are part of the centrarchid family and occupy a niche as both predator and prey within their ecosystem. They primarily feed on smaller fish, insects, and crustaceans. Their role as a top predator in some freshwater systems helps to control the populations of their prey species, maintaining the ecological balance.
