Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 7; Spine anali: 0; Raggi anali molli: 18 - 22; Vertebre: 51. Palatal teeth in two oblique, oval patches; one on each side of palate, well separated. Snout acute; lips fleshy, crenulate; lower jaw truncate. Head shield granular; dorsomedian head groove lanceolate, narrow distally. Eye large, 17-28% HL. Large, flattened serrae along inner margin of pectoral spine; caudal fin lobes slender, acute. Rakers present along posterior face of all gill arches. Distinct, blackish margin on dorsal, pectoral and inner caudal fins (Ref. 40908).
Found in coastal waters, estuaries and rivers within tidal influence; among mangroves (Ref. 40908).
