Environment / Climate / Range
Marine; pelagic-neritic; depth range 0 - 50 m (Ref. 188). Tropical; 30°N - 23°S, 39°E - 129°E (Ref. 188)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 23.0 cm SL male/unsexed; (Ref. 188); common length : 18.0 cm SL male/unsexed; (Ref. 188)
soft rays: 12 - 23. Body moderately slender, belly rather rounded, scutes not prominent. Distinguished from A. sirm by the absence of spots along the flank (gold in life, black on preservation) and fewer lower gill rakers. Closely resembles A. clupeoides, which has fewer lower gill rakers.
