Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 11 - 12; Épines anales: 0; Rayons mous anaux: 12 - 13; Vertèbres: 42 - 43. Upper jaw distinctly wider than long. Snout uniform brown without any dark band on the midline. Pectoral fin shorter than head length. Lower jaw much shorter than head. Sixth and seventh anal rays of adult males greatly thickened and elongated, both rays reaching beyond the caudal base. Either dorsal ray 4 or 5 or both elongated and thickened.
Body shape (shape guide): elongated; Cross section: oval.
Inhabit shallow water around mangrove in sheltered bays (Ref. 26367). Early juveniles are neustonic and float on the surface of estuarine mangroves (Ref. 43081).
