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).
