Key identification features
- Slender, elongate body, golden-bronze with faint wavy dark lines and small dark specks scattered along the back
- Small barbels along the edge of the lower jaw, usually several tiny fringing points
- Inferior (underslung) mouth suited for bottom feeding on worms and small invertebrates
- Slightly rounded tail fin and a spiny, saw-edged preopercle
- Grows to around 30-40 cm; produces an audible croaking or drumming sound when handled
Common look-alikes
- Spot croaker: shows a single dark spot behind the gill cover and clean diagonal bars, and it lacks chin barbels.
- Black drum juveniles: have larger, more numerous barbels and bold vertical bars rather than wavy speckled lines.
- Silver perch: lacks any chin barbels and has a plainer, more uniform silvery body without wavy dark markings.
Where you'll see one
Atlantic croaker are common in shallow coastal waters, estuaries, and bays along the western Atlantic and Gulf of Mexico, over mud or sand bottoms, moving offshore into deeper water during cooler months.
