The spotted bass (Micropterus punctulatus) is a freshwater fish native to the central and southeastern United States. The species closely resembles largemouth and smallmouth bass but can be distinguished by a more streamlined body, a smaller mouth that does not extend past the eye, and a distinct row of dark spots along its lower sides. Spotted bass typically grow between 12 and 24 inches in length and weigh up to 5 pounds, though larger specimens have been recorded.

This species prefers clear, flowing waters such as rivers, reservoirs, and deep lakes with rocky or sandy bottoms. It is an opportunistic predator, feeding on small fish, crayfish, and insects. Compared to largemouth bass, spotted bass are more tolerant of strong currents and are often found in deeper water. Spawning occurs in late spring when males build nests in shallow areas and guard the eggs until they hatch. Spotted bass are known to be aggressive fighters, making them a popular target for sport fishing. They have been introduced to various regions outside their native range, sometimes competing with native fish species. While not as well-known as largemouth bass, the spotted bass is a resilient and adaptable species, thriving in a variety of aquatic environments.

Fun Fact: Spotted bass can hybridize with other bass species! In areas with overlapping ranges, it can interbreed with large- and smallmouth bass.
