Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 9 - 10; Épines anales: 3; Rayons mous anaux: 9 - 11. Diagnosis: Ambassis ambassis has the following combination of characters: a single supraorbital spine; rostral spine absent; preopercle ridge and rear margin serrate; interopercle edge smooth except for few small serrae at angle; 2-3 rows of cheek scales; predorsal scales 13-18; lateral line continuous (normally); lower gill rakers 19-23; pectoral-fin rays 14-15 (Ref. 50956).
Body shape (shape guide): short and / or deep; Cross section: oval.
Tolerant of freshwater when water temperature is within 7-32°C (Ref. 7248, 79840). Tends to be more tolerant of lower temperatures in water of low salinity (2ppt) than in seawater (Ref. 7248). Feeds at night on crustaceans, fish fry and larvae and insects (Ref. 7248). Salt dried and eaten in some countries (Ref. 12484)
