(total): 6 - 7;
soft rays: 11. Body with a series of 6 vertically-elongate dusky blotches along lower side of body, with a horizontal series of dark brown dots or short dark brown lines on each dusky blotch forming a row from beneath upper part of pectoral fin to mid-base of caudal fin; a series of less distinct dusky blotches dorsally on body, not in alignment with lower blotches, and numerous small dark brown dots which tend to form groups on the dusky blotches. [Specimens from the SW Pacific and dark habitats, such as on volcanic sand, may have continuous dark lines on the body]. A large dark brown blotch containing a small bright yellow spot above base of pectoral fin. A narrow, vertical, dark brown to black bar on cheek below centre of eye (sometimes with 1 or 2 short oblique side branches); a narrow black bar usually present in line with or just anterior to rear edge of pupil. An oblique dark mark on opercle. A dusky stripe on pectoral-fin base at level of 6th to 7th rays and extending onto proximal part of fin. Dorsal and caudal fins with numerous small brown spots. Large adults with a long brown streak on each inter-radial membrane of second dorsal fin and with numerous dark dots on pectoral fins. Cheek anterior to dark bar below the eye usually with a few small scales. Prepelvic scales extending to vertical at rear margin of preopercle. Mouth slightly inferior, gape slightly oblique. Scales in longitudinal series 30. Transverse scale series 9.5. Pseudobranch filaments 6 (Ref. 41653).
Indo-Pacific: Red Sea and East Africa to the Hawaiian, Marquesan and Society islands.
Solitary or in loose groups in sand (Ref. 90102). Inhabits shallow coastal bays and estuaries on silty sandy substrates with sparse algae-reef or seagrasses (Ref. 48637). Benthic (Ref. 58302).
