Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 11; Các vây lưng mềm (tổng cộng) : 15 - 17; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 8. This species is distinguished by the following characters: body depth 2.8-3.5 in SL (10-17 cm SL individuals); head length 2.5-2.6 in SL; preopercle rounded, ventral serrae slightly enlarged; upper edge of operculum convex; midlateral part of lower jaw with 3-5 rows of teeth; gill rakers of first gill arch 7-9 + 17-19; dorsal spines 5th-9th subequal (2.5-2.8 in HL); second anal spine 2.1-2.5 in HL, distinctly longer than third spine or depth of peduncle; caudal fin rounded; pectoral-fin rays 17-19, fin length 1.6-1.9 in HL; pelvic fins 1.8-2.1 in HL; lateral-line scales 61-70; lateral scale series 93 to 114. Colour: head and body covered with polygonal (mostly hexagonal) brown spots that tend to merge, leaving only conspicuous triangular white dots at corners of the polygons; dark spots on belly and ventral part of head more rounded and separated, and often reddish brown; 4 or 5 brownish black saddle blotches (formed by groups of darker spots) on dorsal part of body and caudal peduncle, the first 4 extending onto base of dorsal fin; irregular dark bar, formed by darker polygonal spots, on lower part of body below each saddle blotch; large brown or olive spot just behind eye, often joined to similar spot on opercle; fins with close-set dark brown or reddish brown spots and white dots, except distal half of pectoral fins with faint dark spots and no white dots; pelvic and anal fins with pale edge and dark brown submarginal band; interspinous dorsal-fin membranes with dark brown triangle and short white or pale yellow filament behind tip of each spine (Ref. 39231, 90102).

Sinh học     Tự điển (thí dụ epibenthic)

Common in exposed outer-reef areas in relatively shallow water. Well-camouflaged grouper, solitary (Ref 37816). Feeds mainly on fishes and crustaceans (stomatopods and brachyuran crabs) (Ref. 5222). This fish is too small to be of commercial importance except as a food fish in artisanal fisheries. It is caught with hook-and-line, traps, spear, and gill nets (Ref. 39231).
