Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 7 - 9; Radios blandos dorsales (total) : 12 - 14; Espinas anales: 0; Radios blandos anales: 10 - 12. Four preopercular spines, the uppermost curved upward (Ref. 559). Supraocular cirrus simple (Ref. 559). Pelvic fin united with belly by means of a wide dermal fold (Ref. 559).
Common in the littoral zone at depths up to 30 m. Probably spawns in the littoral zone and its larvae and fry are transported to river estuaries in tides (Ref. 26949).
