Source-derived summary

The redear sunfish (Lepomis microlophus), also known as the shellcracker, Georgia bream, cherry gill, chinquapin, stumpknocker, and sun perch, is a freshwater fish in the family Centrarchidae and is native to the southeastern United States. Due to its popularity as a sport fish, it has been widely introduced across North America.

Description

Redear sunfish generally resemble bluegill except for coloration and somewhat larger maximum size. The redear sunfish also has faint vertical bars traveling downwards from its dorsal. It is dark-colored dorsally and yellow-green ventrally. Unlike bluegill, the male has a cherry-red edge on its operculum; females have orange coloration in this area. The adult fish are between 20 and 24 cm (7.9 and 9.4 in) in length. Max length is 43.2 cm (17.0 in), compared to a maximum of about 40 cm (16 in) for the bluegill. Redear sunfish on average reach about 0.45 kg (0.99 lb), also larger than the average bluegill.

Habitat and range

Redear sunfish are native to the southeastern United States.

Editorial summary

The public source identifies “Redear sunfish” as species of fish. This brief keeps that definition visible, then builds a research path around Redear, sunfish and species.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 166-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Redear, sunfish and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Redear sunfish”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jan 28, 2026. The linked authority identifier is Q2741147. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
