Etymology: Drepane: Greek, drepane = sickle (Ref. 45335). More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; reef-associated; amphidromous (Ref. 51243); depth range 10 - 49 m (Ref. 86942). Subtropical; 32°N - 26°S, 32°E - 160°W
Indo-West Pacific: temperate and tropical waters from India to northern Australia, New Guinea, Indonesia, Philippines, Taiwan and Japan.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 25 - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 9710); common length : 25.0 cm TL male/unsexed; (Ref. 3283)
(total): 8 - 10;
soft rays: 17 - 19. Color generally silvery with greenish tinge above. Pectoral fins long and pointed. Similar to D. longimana but differs in having 4 - 11 vertical gray spots on the upper half of the sides, and generally 8 dorsal spines (against none (spots) and generally 9 spines in D. longimana).
Occurs in various inshore habitats: sand or mud bottoms, reefs, estuaries and harbors (Ref. 9800). Found near coral and rock reefs at temperatures ranging from 26° to 29°C. Feeds on invertebrates and benthic fishes (Ref. 5213). Generally marketed fresh (Ref. 5284).
