Characteristic Dorsal fin with IX spines and 14 to 16 rays, the fin origin over rear end of operculum; dorsal-fin membranes not (adults) or slightly (juveniles) incised between the spines, dorsal-fin spines slender, the dorsal-fin spines not much thicker than the dorsal-fin rays; anal fin with III spines and 9 or 10 rays, anal-fin spines slender; pectoral fins rounded, with 18-1 9 rays, the middle rays longest; pectoral fins slightly longer than pelvic fins; pelvic fins not reaching anus: caudal fin truncate to slightly emarginate, with 8 branched rays and 9 to 10 procurrent rays in upper part and 7 branched rays and9 to 10 procurrent rays in lower part. Midlateral-body scales ctenoid, with numerous auxiliary scales; lateral-line scales 66 to 76; lateral-scale series 101 to 114. Supraneural bones distinct, the posterior one more than half length of first one; epipleural ribs on vertebrae 1 to 9; dorsal fin with the posterior 3 to 5 pterygiophores trisegmental; posterior 3 to 4 pterygiophores of anal fin trisegmental; rear edge of first dorsal-fin pterygiophore not excavated for tip of third neural spine; cranium broad, its greatest width more than half its length; least interorbital width more than 25% of cranium length; supraoccipital crest and parietal crests not extending onto frontals; frontopterotic ridges extend past midpoint of orbit; mesethmoid pit deep and cancellous; parietals with a prominent lateral process extending posteriorly over the pterotic bone. Colour: Adults greenish or reddish brown to brownish grey, with several narrow curved dark bars on midlateral part of body and dark brown spot midlaterally on caudal peduncle; 3 to 5 blue lines (often broken into spots) across the head (the upper 2 lines may serve as margins for a mask-like dark band from snout to end of opercle, enclosing the eye); region under maxilla and along edge of gill opening often orange; soft dorsal and anal fins with narrow blue margin; upper and lower edges of caudal fin darker than rest of fin. A transient colour phase has the caudal peduncle white, with a prominent black spot, and a large white area flanked by black areas on dorsal part of body. Juveniles brown or violet, with a bright reddish orange stripe in dorsal and anal fins and along upper and lower edges of caudal peduncle and fin.
habitats G. albomarginata is an active swimmer that roams over the reef; it is usually foundon the outer reef slope in depths of 15 to 120 m. It is an uncommon and (like most groupers) usually solitary species, but Myers (1989) reports occasional sightings  
Distribution northern Mozambique to French Polynesia. In the western Pacific it ranges from Okinawa to the northern Great Barrier Reef. Most records are from islands and off shore coral reefs, including Zanzibar, Comoros, Seychelles, Chagos, Mauritius, Reunion, Maldiv 
Utility Not abundance for food species, edible, palatable.
