Etymology: Alepes: Greek, alepis, -idos = without scales (Ref. 45335). More on author: Forsskål.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; amphidromous (Ref. 51243). Subtropical; 46°N - 37°S, 19°E - 138°W
Indo-Pacific: Red Sea and East Africa (Ref. 12484) to the Hawaiian Islands, north to Japan, south to Australia. Immigrant to the eastern Mediterranean through the Suez Canal, wetward to Malta (Ref. 33971).
Length at first maturity / Size / Weight / Age
Maturity: Lm 16.3  range ? - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 11228); common length : 25.0 cm FL male/unsexed; (Ref. 3397); max. published weight: 124.00 g (Ref. 4883)
Adults form large schools near inshore reefs (Ref. 30573). Feed on shrimps, copepods, decapod larvae and other crustacean larvae and small fish (Ref. 5213, 90102). Eggs are pelagic (Ref. 4233). Often caught by ski-boat anglers in southern Africa (Ref. 12484).
