Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 8; Μαλακές ραχιαίες ακτίνες (συνολικά) : 9 - 10; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 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).
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)
