Length at first maturity / Size / Gewicht / Alter
Maturity: Lm ?, range 25 - ? cm
Max length : 50.0 cm TL Männchen/unbestimmt; (Ref. 9710); common length : 25.0 cm TL Männchen/unbestimmt; (Ref. 3283)
Rückenflossenstacheln (insgesamt) : 8 - 10; Rückenflossenweichstrahlen (insgesamt) : 20 - 22; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 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).
