Etymology: Aprion: Greek, a = without + Greek, prion = saw (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 180 m (Ref. 9710). Tropical; 35°N - 31°S, 33°E - 134°W (Ref. 55)
Indo-Pacific: East Africa to the Hawaiian Islands, north to southern Japan, south to Australia.
Length at first maturity / Size / Weight / Age
Maturity: Lm 44.9, range 42 - 50 cm
Max length : 112 cm TL male/unsexed; (Ref. 7196); common length : 90.0 cm TL male/unsexed; (Ref. 5450); max. published weight: 15.4 kg (Ref. 40637)
Adults inhabit open waters of deep lagoons, channels, or seaward reefs (Ref. 9710). Benthopelagic (Ref. 58302). Usually seen singly, but also in groups. Feed mainly on fishes, but also on shrimps, crabs, cephalopods and planktonic organisms (Ref. 30573, 48635). Mainly marketed fresh but also dried and salted. Excellent eating. Large individuals may be ciguatoxic (Ref. 37816).
