Key identification features
- Deep-bodied, moderately compressed silvery fish with a slightly humped back
- A single, bold black spot at the base of the pectoral fin, the species' most reliable field mark
- No barbel on the chin
- Blunt, rounded snout with a small, low mouth suited to digging in sand
- Typically 12-18 inches, heavier-bodied than most other local croakers
- High, arched dorsal profile and fairly broad, rounded fins compared to slimmer surf croakers
- Overall bright silvery sheen that can look almost metallic when fresh out of the water
Common look-alikes
- Yellowfin croaker: shows diagonal wavy stripes and yellow-tinged fins but no black pectoral spot
- California corbina: has a single long chin barbel and a plain slate-gray back, lacking the pectoral spot entirely
- Black croaker: overall dusky to blackish body coloration rather than bright silvery sides with an isolated spot
Where you'll see one
Common along sandy surf beaches and shallow bays of southern California and Baja California, often feeding in the wash close to shore alongside corbina and yellowfin croaker in mixed schools.
