Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 14-15; Anal spines: 3; Anal soft rays: 8. Small juveniles (<8 cm) with small hexagonal spots on head and body becoming larger posteriorly and on vertical fins (Ref. 37816); distinguished by pale yellowish brown color with five vertical series of irregular dark brown blotches; head, body and fins with numerous close-set, small brown spots; caudal peduncle with small black saddle dorsally; cycloid scales except ctenoid in juvenile; body with auxiliary scales; moderately deep bodied, greatest depth 2.6-2.9 in SL; pelvic fins 2.1-2.4 in head length (Ref. 90102); further characterized by having head length 2.3-2.5 times in SL; flat or slightly concave interorbital area; adults dorsal head profile indented at eyes and distinctly convex from there to origin of dorsal fin; rounded preopercle, finely serrate; distinctly convex upper edge of operculum, descending almost vertically to rear end of operculum; deeply indented anterior edge of preorbital bone below nostrils; triangular posterior nostrils, 4-7 times larger than anterior nostrils in adults; maxilla extends well posterior to eye; 3-4 rows of teeth on midlateral part of lower jaw, inner teeth twice as long compared to outer teeth; canines inconspicuous; nostrils are close together (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Occurs in lagoon pinnacles, channels, and outer reef slopes, in coral-rich (Ref. 1937) areas and with clear waters. Juveniles in seagrass beds (Ref. 30573, 41878). Feeds on fishes, crabs, and cephalopods. May be ciguatoxic in some areas (Ref. 1602). Mainly active at dusk (Ref. 48635). Palau fishers increase their drop-line and spear-gun catches through knowledge of reproductive cycle of remochel, one of most important species in the area (Ref. 2928). Cultured under experimental conditions in the Philippines; a candidate for aquaculture in Singapore. In Hong Kong live fish markets (Ref. 27253).
