توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 10; شعاع نرم باله پشتي (کل) : 13 - 14; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 8. This species is distinguished by the following set of characters: D X, 14 (13-14); A III, 8; body depth 2.4-2.8 in SL; eye 3.7-4.8 in HL; interorbital 5.6-7.4 in HL; scale rows above lateral line rising obliquely toward dorsal profile; predorsal scales extend forward to middle of interorbital; preopercular notch and interopercular knob are weakly developed; vomer with narrow, crescentic, V-shaped patch of granular teeth without a medial posterior extension; caudal fin slightly emarginate. Colouration when fresh or in life reddish brown, grey-brown, or olive-brown on head, back, and upper sides; the lower sides and belly reddish brown or silvery pink in adults and brownish white in juveniles; dorsal, caudal, anal, and pelvic fins are reddish brown, with a black spot at base of uppermost pectoral-fin rays; two dark-brown stripes on the upper half of lateral body, first from upper end of operculum to posterior end of soft-dorsal-fin base, continuing to upper caudal-fin base and the second stripe from behind upper middle operculum straight to mid-base of caudal fin, preceded by a squarish dark blotch on upper operculum (Ref. 138536).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Inhabits coral-associated rocky reefs, mostly at about 3-20 m depth from where it is mostly fished. Juveniles often found in shallower waters, in less than 5 m. It is not known to occur in estuarine areas or in soft bottom trawling grounds. This species is the most frequently caught snapper (lutjanid), regularly seen in hand-line catches and occasionally in bottom-set gill net catches around Zinjira Island, Bangladesh. Associated species in catches are Lutjanus indicus, L. johnii, L. lunulatus, Lethrinus sp., Paranibea semiluctuosa, and Pomadasys guoraca, among others (Ref. 138536).
