Length at first maturity / Taille / Poids / Âge
Maturity: Lm 21.0  range ? - ? cm
Max length : 31.6 cm TL mâle / non sexé; (Ref. 121654)
Épines dorsales (Total) : 9; Rayons mous dorsaux (Total) : 21 - 22; Épines anales: 3; Rayons mous anaux: 17 - 18. This species is easily recognized by its long pelvic fin which fit into a groove along the midline of the belly when depressed. Scutes are present along its straight lateral line. Adult males have prolonged middle rays in the soft dorsal and anal fins. This species attains 25 cm in SL.
Adults are common in shallow coastal waters where they often swim near the surface. They feed mainly on shrimps, copepods, decapod crustaceans and small fish.
