Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 8 - 10; Rayons mous dorsaux (Total) : 20 - 22; Épines anales: 3; Rayons mous anaux: 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).
Body shape (shape guide): short and / or deep; Cross section: compressed.
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).
