Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 8 - 10; Dorsale zachte stralen (totaal) : 20 - 22; Anale stekels: 3; Anale zachte stralen: 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).
