Etymology: Diagramma: Greek, diagramma = mark out by lines (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 1 - 170 m (Ref. 12260), usually 1 - 50 m (Ref. 37816). Tropical; 35°N - 35°S, 25°E - 170°E

Length at first maturity / Size / Weight / Age
Maturity: Lm 31.8, range 32 - ? cm
Max length : 100.0 cm FL male/unsexed; (Ref. 3678); common length : 55.0 cm TL male/unsexed; (Ref. 5450); max. published weight: 6.3 kg (Ref. 4699)
Typically found solitary or in groups, often in turbid water. on open muddy, sandy or silty substrates in protected bays or estuaries, around rock outcrops, wreckage and debris (Ref. 48635, 90102). Also in shallow coastal areas and coral reefs (Ref. 30573). Juveniles are found in weedy areas (Ref. 2799). Feeds on benthic invertebrates and fishes (Ref. 30573). Reportedly ciguatoxic in some areas (Ref. 2799). Marketed fresh and frozen (Ref. 9987). Five subspecies recognized across Indo-Pacific region including D. p. labiosum and D. p. pictum (Ref. 90102)
Distinct pairing during breeding (Ref. 205).
