Identification. A small species of Clupeidae (maximum TL about 100 mm); body deep, laterally compressed and strongly keeled from isthmus to anus; mouth small inferior; last dorsal fin ray not filamentous; lower gill rak- ers 54–96 (on first gill arch; data from Whitehead 1985); longest gill rakers on lower part of arch less than corresponding gill filaments; posterior edges of scales in- dented, the indentations smaller than gaps between them; body silver, back darker; a large, dark, ovoid mark behind upper part of gill opening, covering about four scales. Fins mostly translucent ( Whitehead 1985).

Anodontostoma chacunda can be distinguished from other clupeids collected by its deep body, high number of lower gill rakers and a conspicuous large dark ovoid mark behind upper part of gill opening. Anodontostoma chacunda is a predominantly coastal marine species and one of the most common species of Clupeidae occurring in brackish ecosystems of this region (e.g., Tongnunui et al. 2002; this study). Otherwise, distributed in

the Indo-West Pacific region, from the Persian Gulf to Australia ( Whitehead 1985).
